关于珍珠



南洋 South Sea 指 the Indian and Pacific Oceans, primarily in Australia, the Philippines, Indonesia and Myanmar,南洋珠的贝学名叫Pinctada maxima mollusk。其珍珠颜色有金色或者白色,因为贝大,人工放入的 implanted bead 大,,产的珠子平均13MM,而且一个贝一珠,珠的成长期大概要超过2年。

上图里的珠子大概有14 mm, 算大的了。


大溪地是Tahitian, ,其实珠子大部分是从French Polynesia法属殖民地所产,Tahitian 是一个销售中心。 贝学名叫black-lipped oyster ‘Pinctada margaritifera, 可重达10 LB. 这个品种的珠子是深色的,俗称黑珍珠,大小介于南洋和akoya之间。其实大部分颜色并不是全黑,带孔雀绿,灰的。真正的全黑很少很贵。miki喜欢称大溪地为南海黑珍珠,个人认为不准确。

上图包含了大溪地珍珠的颜色的几种。特别光洁的比有纹路的要贵好多,尽管不圆整的有时光泽很好。





Akoya是冷水海洋珠,贝小,所以珠子也小个,白色为主,日本中国沿海有产。一个akoya贝 可放5个仔,但平时最多放2个。在采珠后就死了。Akoya的特点是圆和亮。 做首饰最好。

说到贝,Pictada margaritifera 和 Pinctada maxima 一次可种一个nucleus, 可种好几次不死。如果某个贝产好珠, 就会被放生,把好的遗传因子发扬光大。
南海珠是珍珠里的KING. 和其它海珠比。它的珠层nacre 厚度 2 - 6 mm, 而AKOYA 才0.35 - 0.7 mm。


Akoya 的珠子被日本人规范化了。有统一的级别标准。但南海珍珠和大溪地的等级不统一。各个商家有不同标准。 珍珠的评级都是卖家自己评的,主观性很大,有多不良卖家就赌你不识货,也有些还挺靠谱。

珍珠要在大小、光泽、瑕疵这几个点做一个平衡,总有一点要妥协一下,除非你特别有钱。技术参数不一样的珍珠不好比,商家就是抓住这一点抬价,反正没有一模一样的,完全可比较的也不好找,所以你很难比较价格。

10mm以下的南海珠不要买,太小的南海珠珠层薄,光泽不可靠。南海不管淡金还是正金色都可以极漂亮,主要看光泽。它的光泽和akoya 不一样,akoya 像镜面一样锐利,南海珠子的光像上好的绸缎。

市场上的akoya珍珠基本上没有不经过浅染色的,miki也不例外,实际上,这种技术就是他家发明的。不过 这种处理是永久性的。非白色的akoya自然状态下其实很多,多是浅灰和香槟色,这种珠子达到珠宝级别的不多,再说主流审美还是喜欢白色的,南洋珠是不用染色的,市场上染过色地要么是淡水珠假冒,要么是不良商人为了加深金 珠的色调.
买珍珠不要看他们的评级,就用肉眼看就行了,好的珍珠那个光泽,看一次就忘不了,没经验就对比着看,珍珠在珠宝里面最容易入门了,肉眼多看就行,什么仪器都不需要。

CAN humanity exist in artifice

“Her” is one of those movies  that has long haunting effect on the viewers, it is also very funny, at times, painfully so, and erotic (in total black out). Definitely one of the films of the year.
 大部分人看了后都觉得是一部很妙的罗曼史,提到对人际关系的醒悟, 可我为啥看到的是某种无可奈何的悲哀, 人到了那时只能与机器对话才能插出花火,  OS( 操作系统)不但有声音, 有个性,有感情 ,并且她有能力跟你一起成长。 不要提她的智能和EQ可以超过大部分人, OS比你自己都懂你。除了没有血和肉。人性和智慧比一般人都要灵光的多了。

虽然电影的背景是在不远的将来,但人人都挂个电话之类的机器,一有空就喵一眼的场景现在也是到处可见。可以肯定如果技术继续发达,完全可以造出有肉的有情感的机器人。到时候,人和人的交往更困难了。最终社会和人类会不会被机器所掌握?被生产高智能的集团控制?

Tim always fleets away faster than you would like it to. Today is the first day of 2014, and also my birthday.  I don't want to promise any new year goal that I cannot meet, I only want to enjoy an easy day.
The weather is OK about 46F, not much wind like yesterday, My son was on the driver seat and we went to a nearby town Bethesda, we were able to walk on the street for about two hour.

Reading List of 2014

I probably can only read one book a month, so I have to make a choice  from Book Group Favorites:

Here is the list for myself:

MRS. POE

Lynn Cullen

 

Inspired by literature’s most haunting love triangle, award-winning author Lynn Cullen delivers a pitch-perfect rendering of Edgar Allan Poe, his mistress’s tantalizing confession, and his wife’s frightening obsession . . . in this “intelligent, sexy, and utterly addictive” (M. J. Rose) new masterpiece of historical fiction.
1845: New York City is a sprawling warren of gaslit streets and crowded avenues, bustling with new immigrants and old money, optimism and opportunity, poverty and crime. Edgar Allan Poe’s “The Raven” is all the rage—the success of which a struggling poet like Frances Osgood can only dream. As a mother trying to support two young children after her husband’s cruel betrayal, Frances jumps at the chance to meet the illustrious Mr. Poe at a small literary gathering, if only to help her fledgling career. Although not a great fan of Poe’s writing, she is nonetheless overwhelmed by his magnetic presence— and the surprising revelation that he admires her work.
 What follows is a flirtation, then a seduction, then an illicit affair . . . and with each clandestine encounter, Frances finds herself falling slowly and inexorably under the spell of her mysterious, complicated lover. But when Edgar’s frail wife Virginia insists on befriending Frances as well, the relationship becomes as dark and twisted as one of Poe’s tales. And like those gothic heroines whose fates are forever sealed, Frances begins to fear that deceiving Mrs. Poe may be as impossible as cheating death itself. . . .

Sweet Tooth

Ian McEvan


Cambridge student Serena Frome's beauty and intelligence make her the ideal recruit for M15. The year is 1972. The Cold War is far from over. England's legendary intelligence agency is determined to manipulate the cultural conversation by funding writers whose politics align with those of the government. The operation is code named "Sweet Tooth." Serena, a compulsive reader of novels, is the perfect candidate to infiltrate the literary circle of a promising young writer named Tom Haley. At first, she loves the stories. Then she begins to love the man. How long can she conceal her undercover life? To answer that question, Serena must abandon the first rule of espionage: trust no one.


Wild

From Lost to Found on the Pacific Crest Trail

Cheryl Strayed
A Best Book of the Year: NPR, The Boston GlobeEntertainment Weekly, Vogue, St. Louis Dispatch 

At twenty-two, Cheryl Strayed thought she had lost everything. In the wake of her mother’s death, her family scattered and her own marriage was soon destroyed. Four years later, with nothing more to lose, she made the most impulsive decision of her life. With no experience or training, driven only by blind will, she would hike more than a thousand miles of the Pacific Crest Trail from the Mojave Desert through California and Oregon to Washington State—and she would do it alone. Told with suspense and style, sparkling with warmth and humor, Wild powerfully captures the terrors and pleasures of one young woman forging ahead against all odds on a journey that maddened, strengthened, and ultimately healed her.
