London Calling: Serving busy OEMs pays off

London Calling: Serving busy OEMs pays off


Silicon & Software Systems Ltd. otherwise known as S3 Group, has been a center of IC design in Dublin, Ireland, for more than 25 years. But the fast pace of technological and business change in the semiconductor business means that longevity is no guarantee of success. However, longevity does indicate a company that is prepared to adapt to survive.

As a company S3 does more than design circuits. It has business units in digital TV software and telehealth systems, which in a way reflect the origins of the company. It was originally set up by Philips Semiconductors as a remote design base in Dublin, so that it didn't have to keep relocating graduate engineers from Ireland to Eindhoven in the Netherlands.

S3 has been independent of Philips and supplying mixed-signal IP and IC design services for many years but it has to remain flexible and be ready to adapt, Dermot Barry, vice president of silicon, told me in a recent telephone conversation.

Barry relates how 2008, a good year for S3, was followed by very poor 2009. He reckons that IP licensing enquiries had started to pick up again in 4Q09 but that the IC design service business took longer, until mid-2010. And there was a change that helped S3 climb back up. "The traditional customer base is semiconductor IDMs and fabless chip companies. That's changed. We started to go after the OEM companies," said Barry.

He makes the point that semiconductor companies have been under enormous pressure to reduce the cost of their chips for many consumer and mobile applications and that pressure has been pushed up stream. And in the design services business large Indian and Asian service providers, such as Wipro, have been driving down cost.

"We had to focus on our expertise in mixed-signal IP and looked to help OEMs who have electronic products but only in relatively low volume." These OEMs, used to taking standard components from distribution channels could not go to system-chip because they lacked the expertise and access to foundry, said Barry.

"By a mix of integration of repartitioning systems we've been able to achieve bill of materials savings." The volumes remain small but S3 works with foundry access aggregators such as eSilicon, Open-Silicon and Delta Microelectronics to help the OEMs get access to appropriate foundry processes and production volumes.

Barry makes the point that when talking with IDMs and fabless companies that are familiar with the design process the discussion can get focused on the price whereas with negotiations with OEMs can revolve around the value created in terms of savings in the system BOM.

It all goes to show that as an engineer, in terms of achieving the best return on your efforts, it is not only what you do that matters but also for whom you do it. And that taking the system and user-case point of view usually yields far more efficient and cost-effective solutions.

Globalfoundries' FinFET wafers set to roll

Globalfoundries' FinFET wafers set to roll



LONDON – The first multiproject wafer runs for customers testing Globalfoundries' 14-nm FinFET manufacturing process technology could start as soon as the first quarter of 2013, according to Mike Noonen, executive vice president of worldwide marketing and sales at the foundry chip maker.

Globalfoundries Inc. (Milpitas, Calif.) is pushing hard to get customers into volume production with chips on its14XM process in 2014, just one year after introducing a 20-nm process. In part it is trying to do this by reusing the middle and back-end processes from the 20-nm process while replacing planar transistors with FinFETs thereby making for an easier transition. A move from 20LPM to 14XM is expected to produce improved power and performance albeit at approximately the same die area.

Noonen said that 14XM mutiproject wafer (MPW) runs could take place in the first or second quarters of 2013 and would be used by early adopters of the process to run test circuits. Globalfoundries started offering early physical design kits for 14XM in September.

When asked if the 14XM process was still liable to receive tweaks as a process, or even to major changes such as the use of silicon-on-insulator (SOI) wafers as a starting point to improve manufacturability Noonen said: "14XM is a bulk process."

However, Noonen added that Globalfoundries does have experience in other process technologies that make use of SOI wafers. "We have additional strong alliances on fully-depleted SOI. We are the manufacturing partner for STMicroelectronics for FDSOI at 28-nm and 20-nm. We have aligned ourselves with the thought leaders in all the manufacturing processes."

FDSOI uses planar transistors but it could be that logical road-map for both process technologies merges at some point in the future. There has been discussion as to whether the use of SOI can reduce the variability of FinFETs and improve performance at 14-nm. Some think it can while others have cited potential problems with floating-body effects and self-heating.

Noonen said Globalfoundries is already able to run the full 20-nm manufacturing process flow at its recently completed Fab 8 in Malta, New York. Noonen declined to say whether Fab 8 was already running commercial, high volume production of 20-nm circuits for customers.

“There’s an army of unsung engineers who helped invent Ethernet,” says Bob Metcalfe, taking a long drag on his cigarette as he ruminates about the now ubiquitous network technology he described in a memo to colleagues at Xerox PARC on May 22, 1973.

As the smoke curls around his head some of the names and the stories begin to emerge from the distant past. The first is David Boggs, a Stanford grad student who in 1973 was working in the next lab over from Metcalfe at PARC.

Android cutting deeper into iPad's market share

Android cutting deeper into iPad's market share

SAN FRANCISCO—Apple Inc.' share of the media tablet market fell to 55 percent in the third quarter, the lowest it has been since the company launched the iPad and defined the category in 2010, according to new data from ABI Research Inc.

While Apple has maintained its dominance in the tablet market for 10 straight quarters, the firm surrendered 14 points of market share in the third quarter, mainly to Android-based offerings from Amazon, Google and Samsung, ABI (Oyster Bay, N.Y.) said.

"With the introduction of a smaller, lower-cost iPad mini, Apple has acknowledged Android’s beachhead of 7-inch-class tablets, though at the same time, it has failed to deliver a knock-out punch through innovation, pricing, and availability during the most critical selling period of the year," said Jeff Orr, senior practice director at ABI.

ABI analysts don't believe that the iPad mini has challenged 7-inch Android tablets for market share. Instead, the firm said, analysts believe iPad mini has caused demand for standard iPad models to shift down-market. Limited availability of iPad mini could be the saving grace as end-of-year buying ramps, ABI said.

Android now powers more than 44 percent of all tablets shipped, ABI said.

"As the OS of choice for the majority of device OEMs, we expect the Android ecosystem to continue growing in numbers—new manufacturers, better device choices for reaching more markets and more developers finding value from apps and content," Orr said.

Time for engineers to weigh in on immigration

Time for engineers to weigh in on immigration


SAN JOSE, Calif. – Immigration is poised to be the big political issue of 2013, and it’s time engineers weigh in on it.

I know, it seems premature to be calling for a debate about what’s likely to be next year’s big congressional issue. Florida has barely finished counting its ballots from the presidential elections. Most of us are still picking Thanksgiving turkey out of our teeth, and legislators have yet to decide in which direction we will go rolling off the fiscal cliff.

That didn’t stop the IEEE-USA from chiming in on the issue. In a 28-page report released Tuesday (Nov. 26) it argued the current system using a lottery geared to opening the door to a diverse set of nations has outlived its purpose. In its place, the U.S. should make the possession of a science, technology, engineering or math (STEM) degree the key criteria, it suggested.

“The data indicates that swapping the visa lottery for STEM green cards will not diminish the diversity of America’s immigration sources,” the IEEE-USA wrote. “By prioritizing skills it will create and keep jobs in the US,” it said.

The report is timed to give a boost to Republican-sponsored bill in the U.S. House of Representatives. That bill would replace the current lottery system for 55,000 immigration visas with one based on STEM degrees.

I suspect management in the electronics industry will hail the report. When he was CEO of Intel, Craig Barrett used to say a green card ought to get stapled to every STEM degree from a U.S. university.

I assume engineers seeking green cards will support a plan that would put them at the head of the line. Those out of a job or worried about their job security may see such a bill as a threat. But is there a more nuanced debate EEs ought to be having now?

A significant percentage of minority voters in the recent presidential election cast their ballots overwhelmingly for the Democratic ticket. Their votes shifted the debate from whether to how to enact immigration reform.

So like it or not, it’s time to start a thoughtful discussion of the very real complexities of the issues. The IEE-USA decided the place to begin is with a proposal that a technical degree become the key to getting a U.S. green card.

What do you think?

HP Labs sees ARM, Atom, memristors in server future

HP Labs sees ARM, Atom, memristors in server future

SAN JOSE, Calif. – HP Labs continues to make progress on its long term vision of smart memories based on its memristors as alternatives to server CPUs. The devices are one of several new categories of chips likely to seize the moment of disruptive changes in data center technologies and workloads ahead, said an HP Labs researcher.

Separately, Hewlett-Packard Co. is expected to announce within weeks the next steps in its Project Moonshot, its work on ARM- and Atom-based servers. HP is working with a broad group of companies including processor providers AMD, Applied Micro, Calxeda, Cavium and Intel on the project.

So far HP has announced an Atom-based server using Intel’s Centerton processor. It suggested it would use cartridges to flexibly upgrade a single server chassis for a wide range of ARM- and Atom-based chips in 2013 and beyond.

On a three-to-five year horizon, HP Labs is working on what it calls "nanostores." The chips combine memristors and logic that could challenge microprocessors in a new era of designs based on novel system architectures and memory hierarchies, said Parthasarathy Ranganathan, an HP Labs researcher in a keynote at the Server Design Summit here.

“We have the opportunity for new building block,” said Ranganathan. “It’s really a 3-D stack amenable to traditional workloads and even more so to new workloads, really changing the game with potentially a hundred-fold increase in performance per watt."

HP Labs continues to conduct experiments on the nanostore concept with promising results. But Ranganathan declined to provide any specifics, noting the work is still as much as three years from commercial products.

Such devices could ride a confluence of multiple waves of change. “The technology changes and workloads inflections ahead are incredibly interesting for system design,” he said.

In computing, he noted processors made a “sharp right turn” in about 2005 when performance gains for single core processors plateaued and multicore architectures took off.

In storage, disk drive capacity has outpaced data access times. DRAM capacity growth has taken a “soft right turn” from traditional levels of 60 percent a year to about 25 percent a year, he noted.

The rise of server SoCs and eventually 3-D stacks along with flash memory in server designs could help breakthrough such bottlenecks. The changes come about the same time that networking is shifting more deeply from copper to optical links.

Separately, data growth is far outpacing Moore’s Law, driving new workloads. The researcher noted a “growing complexity and dynamism of data access.” Today’s searches increasingly involve accessing multiple real-time and static databases as well as overlaid sources of personal and contextual information.

“Compared to a simple click, which once was just to a single Web server, we now have very sophisticated data analysis from multiple repositories with complex cross correlations,” he said. “It’s big data, but it’s also fast data from multiple streams with deep analytics."

Secret to Eliminating ESD Damage? Read Your Datasheet

Secret to Eliminating ESD Damage? Read Your Datasheet

The scourge of electronic devices -- electrostatic discharge (ESD) -- can be virtually eliminated by designers doing one simple task: reading their datasheets.

Experts advise to read them slowly, carefully, and all the way down to the fine print. Don't overlook a single word, they say. The result could be the elimination of functional failure, shock, or even fire in an electronic device.

"Sometimes designers move too fast and assume they know what something means," Chad Marak, director of technical marketing for Littelfuse Inc., said in an interview. "But without reading all the way down to the fine print, they may find out that the information on that datasheet doesn't mean what they think it means."

A typical IEC 61000-4-2 ESD waveform is characterized by its sub-nanosecond rise time and its short (~100 ns) duration.

London Calling: Pass me that 100 billion euro note

London Calling: Pass me that 100 billion euro note


If it wants to remain competitive in the world Europe needs to find and spend 100 billion euros (about $130 billion) on coordinated nanoelectronics research over the next eight years, according to the organizations Aeneas and Catrene.

An annual spend of more than 10 billion euro would be a considerable increase on what Europe's spending on nanoelectronics has been over the last several years but that is what it is going to take according to a positioning document recently put out jointly by the two organizations called Innovation for the future of Europe: Nanoelectronics beyond 2020.

Aeneas and Catrene are a couple of those typically European organizations set up to represent and influence interests in spending pooled resources on worthy goals, in this case the advancement of nanoelectroncs in Europe. So it should be no surprise that for them the answer is more money.

Aeneas, the Association for European Nanoelectronics Activities, is a non-profit body formed in 2006 that represents about 100 companies and research institutes in Europe. Catrene, the Cluster for Application and Technology Research in Europe on Nanoelectronics, is a four-year collaborative research super project begun in 2008. Over its four years it has assigned about 4 billion euro (about $5 billion) of resources.

So it can be seen that the two bodies are looking for about a 10-fold expansion of that effort into nanoelectronics.

"Despite today's climate of austerity, investing in technologies that will sustain Europe throughout the 21st century and solve important societal challenges such as energy efficiency, security and the aging population, makes economic sense," said Enrico Villa, Chairman of Catrene, in a statement. "We firmly believe that with the right investment and Europe-wide program coordination, the European nanoelectronics ecosystem can increase Europe's worldwide revenues by over 200 billion euro per year and create an additional 250,000 direct and induced jobs in Europe."

Elsewhere in the statement Villa insists that positioning paper "has been put together and endorsed by all the major actors in the European nanoelectronics ecosystem, including large industrial companies, SMEs, research organizations and academic institutes."

That is as may be. Who would not seek to persuade member states and the European Commission of the need to spend more taxpayers' money to R&D. But it also touches on one of the major problems of the European Union.

Flexible electronics breakthrough claimed

Flexible electronics breakthrough claimed

SAN FRANCISCO—Researchers from the University of Pennsylvania have demonstrated the ability to coat nanoscale particles of the semiconducting material cadmium selenide on flexible plastics, a breakthrough that could lead to high-performance electronics on flexible substrates.

The research team, led by David Kim, a doctoral student at Penn's department of materials science and engineering, used spin coating to deposit cadmium selenide nanocrystals dispersed in an ink-like liquid on a flexible plastic sheet. Their work was recently published in the journal Nature Communications.

"We have a performance benchmark in amorphous silicon, which is the material that runs the display in your laptop, among other devices," Kagan said. "Here, we show that these cadmium selenide nanocrystal devices can move electrons 22 times faster than in amorphous silicon."

Besides speed, another advantage cadmium selenide nanocrystals have over amorphous silicon is the temperature at which they are deposited, according to the researchers. While amorphous silicon uses a process that operates at several hundred degrees, cadmium selenide nanocrystals can be deposited at room temperature and annealed at mild temperatures, opening up the possibility of using more flexible plastic foundations, according to the researchers.

  在各种颜色系列中,以绿色系列最佳,其次是黄色.在具体评价颜色好与差时应从四个方面进行观察分析,即浓度、纯度、鲜艳度和均匀度.浓度是指颜色的深浅,一般来讲以中等浓度最好,太深或太浅较差.纯度是指色调的纯正程度,当混入其它色调时,就不纯正了,或叫偏色了,显然,色调越纯正越好,混色时较差.鲜艳度是指颜色的明亮程度,也称色阳,当然,鲜艳程度越高越好.均匀度是指颜色分布的均匀程度,一般来讲,颜色越均匀越好,不均匀则差,但对某些岫玉品种则不然,如花玉,各种红、褐、橙、黄色调与变化多端的花纹,往往构成奇特美丽的画面,反而更加珍贵.

  2.透明度

  透明度对于五类来讲其重要性更加突出,因为单晶体宝石绝大多数都是透明的,差别不大,而王石则不然,明度差别很大,大多数为不透明、微透明或半透明,少数为透明或亚透明,因此透明度好显得更为珍贵.岫岩蛇纹石玉的一个突出特点是总体上透明度较高,不但比其它地区的蛇纹石王透明度高,而且比其它各种玉石的透明度也较高.从市场上各种岫玉雕件统计看,大多数为亚透明或半透明,少数为透明和微透明,不透明者很少.岫玉之所以被称为我国四大名王之一,应该说透明度好起了关键性作用.

  3.质地

  玉石的质地越细越好,越均匀越好.玉石是多晶集合体,晶体颗粒的大小决定了玉质的细腻和粗糙程度,即晶体颗粒度越小则玉质越细腻,晶体颗粒度越大则玉质越粗糙.一般用肉眼观察,如有明显的颗粒感,则玉质较粗,如无颗粒感,则玉质比较细腻,如在1Q倍放大镜下也无颗粒感,则玉质就非常细腻了.总体来讲,岫玉的质地大多数是比较细腻的,少数稍显粗糙.质地与透明度和抛旋旋光性有直接关系,即质地越细腻,其透明度越高,抛旋旋光性越好,表面反光也越强,增加了岫玉的美感,提高了岫王的质量.反之,质地越粗、透明度越差,抛旋旋光性越差,降低了岫玉的质量.

  4.净度

  净度是指宝玉石内部的干净程度、即含杂质和瑕疵的多少.岫玉由于透明度较好,肉眼观察即可看到内部的杂质和瑕疵,易于判断其净度的好坏.

冰种翡翠貔貅价格 保养 赏析 玉观音_玉貔貅_价格_图片_收藏_鉴赏—妙瑞可翡翠网


冰种翡翠貔貅价格

    虽然说冰种的质地是比较好的,但是冰种的翡翠貔貅,价格也是有高有低的,有的冰种翡翠貔貅就在一两千元以内,而有的冰种翡翠貔貅价格就可能在几万元甚至是上几十万元。

    在很多是神话书籍和很多玄幻等武侠小说中,都认为貔貅是是一种凶猛瑞兽,而且还分有雄性和雌性,雄性名为“貔”,雌性名为“貅”,就犹如翡翠一样,红翡就叫做是“雄的、公的”,绿翠则是叫成是“雌的、母的”。在《山海经》和《诸神异记》中记载,貔貅在古代的时候,是一种祥瑞之兽,而且这样的祥瑞神兽是有一角或两角之分的,有单角的称为“天禄”,两角称为“辟邪”。随着时代的变迁和历史结构的演化,现在的翡翠貔貅造型,多是以两角的形象出现。有时候为了表示招财进宝之意,就可以将翡翠貔貅雕琢成是可爱的类型。但翡翠貔貅在古代是可以用来表示哪些奋勇杀敌的战士的。曾有这样的一部京剧《失街亭·空城记·斩马谡》,在其中孔明曾有一句唱词“各为其主统貔貅”,这里的“貔貅”就是指百万雄师。

冰种翡翠貔貅保养

    现在的复古潮流开始复兴的时候,翡翠貔貅的造型开始变得丰富起来,人们也难以去详细的划分。现在比较流行的翡翠貔貅造型,就是翡翠貔貅形状头上是有一角或两角的,在精心细致的雕琢一下,也可以将翡翠貔貅的全身长鬃给雕琢卷起,有时候也会出现雕琢成飞天的翡翠貔貅造型,图案上貔貅是尾巴卷曲,背部生有双翼的。当我们佩戴翡翠貔貅挂坠的时候,我们要学会认的保养。因为翡翠貔貅挂坠是可以为佩戴的主人带来财运,并且是可以吸食四方财运而转嫁到主人身上的。我们在保养翡翠貔貅的时候,如果是翡翠摆件的话,则要让翡翠貔貅采用卧姿,并在翡翠貔貅的嘴巴放上古钱币,有时候也可以让翡翠貔貅趴在玉钱上的。如果是翡翠貔貅挂坠,则是用红线拴住貔貅口里的玉钱,或是将绳子拴在貔貅的尾巴上,用来佩带和把玩。最重要的一点就是不能让翡翠貔貅挂坠变脏,变脏的翡翠貔貅挂坠是不会有什么灵性的,不仅看起来脏脏的很难看,还有可能使主人的财运流失。

Andy Rubin: After rough start, Android goes viral

Andy Rubin: After rough start, Android goes viral


What eventually became Android, the fastest growing software platform to date, started its life as an idea for cameras. Andy Rubin had just left his first job as a chief executive at Danger, the startup that built the Sidekick handset.

“It was one of the first cellphones where you got a real Internet experience including instant messaging and browsing,” said Rubin in an interview in Building 45 of the Google campus as it was being outfitted to handle an expanding Android staff.

During a break in the Cayman Islands in 2003 to ponder what he wanted to do next, Rubin initially “set out to do the same thing for digital cameras, to create the concept of smart cameras like smartphones,” he said.

Upon further study he found the market for digital cameras was flat at about 30 million units a year. “We could give it a boost, but it wasn’t going to dramatically change things, so we rejiggered,” he said.

The idea for an open source operating system for smartphones emerged as the best shot at making a big splash. The name Android reflected Rubin’s lifelong passion for robotics. But back in Silicon Valley potential investors were unimpressed.

“They said he was trying to boil the ocean, that he would need 10 million phones running Android for this to make sense and they rolled their eyes as if that was absurd,” recalled Steve Perlman, a serial entrepreneur who helped introduce Rubin to potential investors and had been his senior at Apple and startups General Magic and Web TV.

At one point, things got so desperate for Rubin he was about to be evicted. He reached out to Perlman just down the street in Palo Alto, Calif., who walked over $10,000 in hundred dollar bills in a manila envelope as the first installment of a larger gift.

“Eventually, he got funding and returned the favor when he got acquired by Google and they paid my rent for next 18 months,” Perlman quipped.

Rubin recruited former colleagues to form his core team at his new startup. Chris White from Web TV was “a trusted innovator in user interfaces” and among the first to see the need to “get maps deeply integrated in the platform,” Rubin said.

Brian Swetland from Danger became “one of the best engineers on Android and created a lot of the architecture and frameworks for it,” said Rubin. “He’s a big advocate of open source and helped us figure out the right licenses to use--he has a great moral compass in open source,” he said.

Former colleagues Rich Miner and Nick Sears had backgrounds at carriers Orange and T-Mobile respectively, assets valuable in creating business and marketing strategies.

Ironically, the team’s decision to use Java but not the Java virtual machine developed by Sun Microsystems later landed it in a high profile court case. Oracle acquired Sun and claimed the Android team infringed its patent rights in a court case where the initial decisions went in Google’s favor.

Yoshida in China: Beijing patent push

Yoshida in China: Beijing patent push


PARIS—Cynics tend to mock the term “Chinese IPR” (intellectual property rights) as an oxymoron—like “future historians” and “military intelligence.”

But as the Financial Times reported recently, “the rapid rise in Chinese patent filings, which have been growing at a rate of more than 20 percent a year, reflects a profound change in cultural attitudes to property, and intellectual property in particular—even if the Chinese system for protecting IP rights still has many deficiencies.”

More important, the growth in Chinese patent filings is likely to affect foreign companies that may have been reluctant to file for patents in China. Instead of dismissing the Chinese patent system as being fatally flawed and Chinese patents as hopelessly defective, foreign companies might be better advised to invest time and resources in filing patents in China to compete with Chinese companies.

Chip market to fall in 2012, rise in 2013

Chip market to fall in 2012, rise in 2013


LONDON – The WSTS industry organization has revised its previous forecasts down and now predicts a weak end to the year for the global chip market.

As a result the global chip market will be worth $290 billion in 2012, down 3.2 percent from 2011 but will recover in 2013 rising by 4.5 percent, according to the World Semiconductor Trade Statistics (WSTS) organization.

WSTS has revised its forecasts for growth in 2012 and 2013 down from previous forecast given in June 2012 of 0.4 percent growth in 2012 and 7.2 percent growth in 2013 (see SIA, WSTS expect flat chips sales in 2012). The reduced expectations are mainly due to uncertainty in the world economy including a slowdown in the Chinese economy.

Other forecasters have been more optimistic recently (see Report: Rising GDP set to boost chip markets).

The 2012 market weakness is broad, WSTS said, with contraction in all geographical regions and all product categories except logic and optoelectronics.

WSTS anticipates the world market to grow 5.2 percent to $319 billion in 2014, with mid single-digit percentage growth across most geographical regions and semiconductor product categories, supported by a healthier global economy.

白底青翡翠

    白底青种翡翠是白色底子(有时候也叫地子)为主,并带有绿色的一种翡翠。所带有的绿色分布均匀或者是像云团装漂浮着,有时候也是绿色成云朵成团、成成块、成片或者是成岛屿状,但是这些绿色只是仅仅的漂浮在白色的底上,而没有正的和翡翠的底子融合在一起。白底青种翡翠大多数是的色泽是呈现斑状分布。白底青种翡翠质地极其细腻但不显温润,我们在自然光下,是可以用肉眼看到翡翠内部结晶体的结构轮廓的。白底青种翡翠的整体不是很透明,只有在很干净的底子部分,才会显得透明一些。用白底青种翡翠做成的首饰,具有如下特点:即是底色雪白,在敲击翡翠首饰品的时候,声音略显得清脆,就宛若金属的的声音一样。

白底青种翡翠用途

    白底青种翡翠质量很优质的话,是可以用来做成翡翠手镯的,做成的翡翠手镯价格多是在几万元到十几万元不等。但最主要的是用来制作成各种类型的翡翠摆件和翡翠手玩件,这就要考校雕刻师的工艺了。往往雕刻师在用白底青种翡翠来雕琢的时候,都要鞥很好的利用翡翠上面的各种形状的绿色进行创意雕工。主要是运用俏色的手法使雕刻的图案具有很美好的寓意,也更能彰显翡翠的质地和色泽。但因为白底青种翡翠质地略属于中等,颜色上也是缺乏厚重的感觉,所以白底青种翡翠雕刻的时候,一般不会去精雕细琢。这就造成了白底青种翡翠的雕刻品并不会具有太高的价值,常是用来做成家庭摆件或者是办公室陈列用品,而不会当成是顶级的收藏品来收藏。

    千元翡翠玉手镯在选购的时候,因为价格本身就属于中低档层次,所以又可能会存在棉柳石纹等瑕疵,这时候我们在选购的时候,要注意看翡翠的棉柳是否含带太多,是否是杂乱无章的,让人看起来觉得整款翡翠玉手镯有点“面目全非”的感觉,那么这样的千元翡翠玉手镯是不值得购买的。而石纹只要不是太多,也不是太明显的话,是可以忽略不计的。在选购千元翡翠玉手镯的时候,我们还要学会一点就是千元翡翠玉手镯的色泽多是淡雅秀丽的,色泽上或深或浅,有时候非常不也不是很均匀,这就要靠顾客朋友自身的把握了,如果色泽分布得比较均匀,色正艳丽的千元翡翠玉手镯,价格多是在七千元以上,万元以下。最后在选购千元翡翠玉手镯的时候,我们还要记住一点,就是千元的翡翠玉手镯的种质多是在糯冰种质地,偶尔也会出现冰种的千元翡翠玉手镯。知道种质后,我们就看看千元翡翠玉手镯的底子是否干净、水头是否足润、透明度的程度如何。只有先抓住千元翡翠玉手镯的这些特性,方能考虑千元翡翠玉手镯的做工。

    翡翠玉石传入中国后,为中国的玉石文化增添了更为丰富的内涵,贵称为玉石之王。翡翠和中国的玉石文化水乳交融之后,承载着我国的玉石文化滚滚向前发展。我们在保养千元翡翠玉手镯的时候,首先要知道,翡翠是具有灵性的玉石,也是具有灵魂的所在。我们要学会不能让翡翠过多的被油渍等污垢所沾染上太久的时间,防止翡翠玉手镯色泽变得黯淡。尤其是在洗衣服的时候,更是要学会不要让玉手镯被洗衣粉水给浸泡得太长的时间,因为翡翠是很怕和强酸强碱在一起的。最后我们要学会洗澡前先把千元翡翠玉手镯给摘取下来,然后再洗澡。如果没有摘取而沾染上洗发水等等化学物质的时候,那么在洗澡完后,就要尽快的用清水将千元翡翠玉手镯给冲洗,再用干净的棉布擦拭干净。
