先把不符合严选标准的排除,我用红色标示了超标的。table,depth查那么一点还是可以考虑,但是最重要的是pavilion和crown的角度,这个要卡死。排除的就用斜体标示,不再考虑了,这样其实只有4个可以考虑。再看c、p角度,最好互补,35配40.6,34配41.0,34.5配40.8,大概这个趋势,那第一个是最好(用了绿色),看HCA值也是适中,girdle稍有不足但是不是硬伤。相比之下,5和最后一个HCA值有点偏大,考虑到最后一个的depth深,table小,基本不用考虑。6的HCA虽然不错,但是又比1贵,又girdle跨这么多级别,c、p配合还不如1。所以我觉得1最好。最好check一下杂质分布和类型,没有硬伤就它吧。你报一下1和6的直径,看查多少。PS下次标个号,我写的时候数得好辛苦。。。 x
你沒存stocking no?很可能啊,各方面都好的好像走得蠻快的,而且好像bn的貨源和其他下游商家共享的,如果一個jewler來挑,肯定挑得快準狠啊。所以不能拖好幾天的,最多三天,保險起見都打電話hold住先。 直徑那個不需要解釋。table外的雜質比較不容易看出來,table內的雜質比較容易看到;明顯程度 in general cloud>feather>crystal>pinpoint,最前2個也看大小啦
这么小的就不要讲求E色了,经济实惠点,买G-H色的好,侧面肉眼G根本看不出,H够大的话,懂行的才能看出一点感觉来。你要不要换color重新挑过?这个价位vs2够了,拿到手确认下eye clear就可以。girdle多数都是faceted啊,我随便查的:A girdle may be faceted (a series of tiny polished sides going around the diamond), bruted (a single continuous unpolished surface going round the diamond; no longer common), or polished (a bruted girdle that has been polished smooth). Whether a girdle is faceted, bruted, or polished usually has no impact on the appearance or value of the diamond.——出处http://www.lumeradiamonds.com/diamond-education/diamond-girdle
也就第二颗(尾数3198)和第三颗(9215)中间选了,我不知道价格,所以你结合我点评的自己选一个:2的角度比例都比较好,唯一缺点是girdle厚薄不均,如果选halo的setting就问题不大,否则最好选6爪的,保护一下thin的部分,strong blue fluor你不介意就好,我见过版上有mm专门买带强蓝荧光的,觉得阳光下看起来很酷。3的偏明亮一点,但是depth比2大,所以也没有直径上的优势,但是没荧光,polish是vg不是ex。

看到mm有很多考量的数据bluenile上面都没有 比如 crown angle,crown height percentage,pavilion angle等等 这些是可以自己算的吗?
第一次看mm的帖子的小白请包涵
BN Stock #: LD05233664
Stock #: LD05241077
Stock #: LD05119989
之前在你的black friday贴子里请你帮忙选过钻的
现在钻买回来了,才发现了girdle reflection这个东西,侧面看好明显的一条线啊,有点膈应,请问真的是每个钻石都有的吗?
谢谢~
我周末去店里看了看 觉得自己可以接受到 ICOLOR
LD05111973
我都沒注意到這個耶,可能是我自己的鑽戒setting在那個部位有個圈圍起來了,看不到。反正我簡單查了一下,是很普遍恨正常的現象。給你個pricescope論壇上的一個帖子看看,http://www.pricescope.com/forum/rockytalky/girdle-reflection-question-t80878.html
建議最低還是H吧。這顆已經不available了,不過看了一下,crown%稍小,其他還不錯,就這個價位來說可以買。
汗。。。那我换一个吧。。。
这个呢
纯看CUT怎么样?
61.4
58
34
40.6
girdle: slightly thick to thick (faceted 4.5%)
I got a HCA of 0.8, but it says its only "very good" cut on blue nile... is it becuz of the girdle????
我自己也research过了,虽然大家都说是正常的,但还是忍不住来问问你才放心。
除了这条线,其他都还挺满意的,就是觉得之间纠结净度什么的都没意义了,反正都有这么明显的线了
我看到这里问的都是大颗的。。。其实有点尴尬。。。希望不要介意。
我不想浪费男友钱。。按经济。。所以挑了小的。。
麻烦有空的话帮忙看看。。感激>__<
纠结了。。。好多天
而且。。不会在GIA里看暇疵。。。。不知哪个部份是囧。。请指教。。
感谢感谢!

我找到一颗数据不错的:
2.01克拉,F,VVS1, 无荧光
table: 56%
Depth: 61.8%
Girdle: medium - slightly thick
Cutlet: none
Crown angle: 34.5
Crown depth: 15%
Pavilion angle: 40.8
Pavilion depth: 43%
HCA: 1.3 (E/E/E/VG)
但是商家不能提供photomicrograph or optical light performance profile.
他们给了一张钻石本身的照片:
这有什么用吗?照片中心的地方为啥不对称啊?
关键问题是数据这么好的石头,实物有问题的可能性大吗?我很怕买了又退,太麻烦
Carat Weight: 1.01c
Color Grade: G
Clarity Grade: VVS2
Cut Grade: Excellent
Finish
Polish: Excellent
Symmetry: Excellent
Fluorescence: None
Inclusions:
Needle (台面边缘一个)
Pinpoint (底部同一个facet边缘两点)
Total Depth: 61.3%
Table Percentage: 57%
Crown Angle: 34.5
Crown Height: 14.5% (貌似这个偏短)
Pavilion Angle: 40.8
Pavilion Depth: 43%
Star facet length: 50% (不好?)
Lower Girdle Facet: 75%
Girdle: medium-slightly thick (faceted) 3.5% (貌似有点偏厚)
Culet: None
这个是陪一朋友去看的,是C家的。朋友决定要品牌的,至少1ct,但资金有限,F色太贵了,VS1/VS2看过觉得inclusion偏多。
mm觉得这款还行么?
最后问一下mm,如果以下5颗呢?
最后5强。。。价格都只差几百rmb。。
GIA report:2161604990 (这颗就是前几天 mm说有点扁的那颗0.31ct)
GIA report:1189161788 -0.33ct
GIA report:2176850157 -0.30ct (只有这个girdle是medium,就是是faceted的,请问影响大吗?因为网上找了说是解为有许多单个的刻面。。。说没有光滑的好?)
以上2颗是退一步选了F色的。。
GIA report:2186167808 -0.35ct
GIA report:2186222234 -0.33ct
以上2颗是同是E色的但是净度是VS2的,
想问一下mm,其实这么小颗是先选 颜色 还是净度呢?
谢谢 迫到内伤了 不懂但天天看。。。。
基本抓住pavilion看。。每个都是medium~slightly thick。。。。吐血
再次谢谢mm的帮忙!
根据你提供的信息,我在bluenile选了几颗钻石,想让你看看那个比较好一些,这些HCA评分都是三个excellent,最后一个vg,麻烦你了,谢谢谢谢!附上图片
土豪姑姑真土豪的话,就不要降了,反正要什么照着买呗。
要是有budget的话,这2个参数不动,也没什么能动的了,低于1ct,有荧光什么的土豪心态更接受不了了。。。

3ex 是啥意思?
数据基本都在严选范围内,除了star% 是50%。但是爬完整个楼看到MM评价过一颗类似的石头,说太扁了。请问太扁了的坏处在哪呢?
Thank you, lzmm!
哪颗比较好呢?还是说应该再找找?我们budget 7000
谢谢!
感谢! 多问一句, 怎么看扁不扁呢? 是指常和宽的DIAMETER不同? 还是说depth不够? 自己初选的时候怎么选择呢?
谢谢mm!
555.... 我好笨, 那几颗有没好点?
LD05320431;LD05348184;LD05399949;LD02212585
有。最后一颗crown %太低,out。第三个角度什么的还不错,不过girdle不太爽。第二个不错,可放心买,就是VVS级别自然稍贵。第一个cut还可以,但是偏长,girdle不是很好,杂质有一团在table内,有点是便宜1000多。不考虑budget推荐的话还是第二
谢谢
都到这边上了,无所谓,但是这个cut不太好,应该会有我第一页里讲deep cut不好的那个效果,中间一圈漏光明显。而且那么偏长,total depth都超严选,强烈不建议买
现在看中两颗石头
第一个是
Carat weight: 1.16
Shape:Round
Cut:Ideal
Color:I
Clarity:VS1
Length/width ratio:1.00
Depth %:62.5%
Table %:56.0%
Polish:Excellent

Girdle:Medium to Slightly Thick
Culet:None
Fluorescence: Strong
冠角:35
亭角:40.8
HCA:1.6
另一颗是:
Carat weight:1.15
Shape:Round
Cut:Ideal
Color:I
Clarity:VS2
Length/width ratio:1.00
Depth %:61.8%
Table %:57.0%
Polish:Excellent
Symmetry:Excellent
Girdle:Medium to Slightly Thick, Faceted
Culet:None
Fluorescence:Strong
冠角:35.5
亭角:40.6
HCA:1.4
价格都是5200左右。你觉得I色的会很暗淡么?另外,如果要选,上面这两颗选哪个比较好?谢谢!!
第二个crown非严选,直接out,第一个depth超标,角度倒还可以。如果你是要1.1ct的话可能是要牺牲点颜色,不过你如果选1.0Xct,而girgle不是这样厚,slightly thin-medium的,而且crown和pavilion角度都是偏小的,其实直径不会比你这个1.1X的小。ps我的id你打错了,不过你不是第一个人。。。。

谢谢您,麻烦您指导一下。
本来已经认真看过三百多石头,挑了七个准备再进一步缩小范围的,结果一刷新,都不见了。。。郁闷半天。
非常感谢lz这么详细的资料。收藏先!
谢谢您的及时回复,我准备再严选。
全部打回去重选
第一个:除了girdle不大好,其他貌似还不错, 请您看看是否可以
HCA 是 0.9
一个 f vs1 hca:ex ex ex vg 0.6 直径6.66-6.69
(1)冠角35.5 不在严选范围,但是亭角40.6 HCA 是EXEXEXVG 1.3 见过一些35.5冠角的也在bn的signature ideal中的,但是是不是漏光的可能性增大了
(2)全深 62.3 但是这个是1.1克拉,比上面那个1.0克拉直径还是大多了的
又选择了个,感觉比较完美了,至少看了60-70个钻石了,吐血。。。。
D色,vs1,台面一个小crystal(会有影响吗?),除了girdle是thin-medium,其他均在严选范围里面。
HCA:0.5 EX EX EX EX
AGS 得分是0
同时也符合BN自己Signature ideal的标准
