这脑洞，老外用图帮大家了解彩色宝石~
提到彩色宝石（简称“彩宝”）
除了能掏空钱包的价格外
大家肯定最关心的就是
宝石的品质好坏
由于宝石学是门系统科学
对于很少接触彩宝的普通消费者
判断一颗彩宝的好坏
时常弄得大家脑壳疼
太专业的术语容易晦涩难懂
太多的骗子又磨刀霍霍
真不知道如何判断一颗彩宝的好坏
旺财最近浏览
国际宝石权威机构Lotus Gem
也就是常被提到的莲花证书开具机构
他们家专业鉴定红、蓝宝和尖晶石XX年
用一些非常直观的图片
帮助大家把彩色宝石看了个光哈哈
下面旺财就一张张的介绍给大家

Which of the above people is most attractive? Most would agree that there is no right or wrong answer, that this is something an individual must personally decide. But when it comes to ranking colored stones, many gemologists (and some dealers) believe it is feasible to create such a ranking. Photos: Getty Images/iStockphoto
上文灰字是英文原文
英语好的宝宝请自行理解
下面是旺财对这段文字的解读
宝石有千面
每一颗宝石都是独特的存在
虽然宝石行业对宝石好坏
有成体系的标准
但在真正热爱宝石的人眼中
宝石没有美丑
你喜欢她
在你眼中她就是最好的
人无完人，石无完石
喜欢就好
The Lotus Gemology Saturation Scale. Note that the highest saturations are out-of-gamut, and so cannot be shown on a printed scale such as this. Saturation of faceted gems is, in most cases, judged by reference to the saturation of the average brilliancy flashes.
The Lotus Gemology Tone Scale. Note that, unlike saturation, tone is judged by the overall lightness/darkness of the stone.
上面的文字是对宝石颜色的描述
颜色好坏三要素是
饱和度、色调和明度
上图是颜色饱和度的描述
下图是色调的描述
饱和度是颜色的纯净度和浓淡
色调是颜色的种类
明度是颜色的亮暗
Clarity can be summarized in a single word: distraction. The degree of distraction can be seen by comparing the smiles above, where it increases as you move to the right. But real life is rarely so simple. With the two rubies above, each has different types of clarity problems. Choosing between them then becomes a personal preference.

这个就绝了哈哈
用牙齿来比喻宝石的净度
从左边的演员牙
到右边的漏风牙
套到宝石上可以理解为
宝石净度、杂质和矿缺的分布
演员牙是肉眼无暇的宝石
发黄牙是丰富包体的宝石
少颗槽牙是瑕疵位置不明显
大牙缝是瑕疵明显但不大
断牙是瑕疵和个头较明显
缺颗牙就是这也太明显了吧
Faceted gemstones display a combination of reflections largely determined by the angles of the pavilion (rear) facets. When pavilion angles are too shallow, light from above leaks through the bottom, creating a “window” (so-called because you can see through the stone). In contrast, if pavilion angles are too deep, light leaks out the side. Light from below also cannot enter, creating dark areas of “extinction.” Only when the angles are correct, does light return to the eye. These intensely colored areas are termed brilliance and in the yellow sapphire shown above, they are all the areas not outlined. Photo: Wimon Manorotkul
Differences between brilliant (left) and shallow (right) gems are vividly revealed above, with the stone on the right showing an obvious window. Just because a gem is shallow does not mean it is poorly cut. The job of the cutter is to return the most expensive stone possible, not necessarily the most beautiful. At times that means saving weight. The lapidary faces a constant battle between weight and beauty. Photo: Wimon Manorotkul
上图就是对切工的图示
切工的好坏包括
比例、对称性和抛光
三者都直接影响宝石美丑
图中很好的诠释了比例不好导致的
漏窗和暗域
对称性和抛光就比较直观了
脸歪了肯定影响颜值
皮肤糙肯定也不好看喽
Lighting can have a dramatic effect on the appearance of any colored gem. Incandescent lighting (left) is rich in red, orange and yellow wavelengths and thus pushes an object’s color in that direction. In contrast, skylight (right) is more balanced, pushing the color in the opposite direction. Illustration: Minolta
上图是光线对宝石颜色的影响
很多客户经常面对一个困惑
为什么照片、视频与实物不一样
为什么不同播放设备看宝石不一样
为什么室内和室外看宝石也不一样
首先需要跟大家说明
宝石本身展现的颜色靠的是光
不同的光源
宝石过滤后反馈出来的光线不一样
所以大家不同光源下看宝石不一样
而照片、视频和播放设备
直接影响宝石真实反馈光线的还原度
这也是旺财建议大家多看实物的原因
只有眼睛在不同光源下
看到拿在自己手里的宝石颜色
才是最真实的宝石颜色
Per carat auction records for ruby and sapphire as of October 2015.
Auction records (per ct) for ruby from 1979 through May 2015.
Sapphire auction records from 1979 through 2015.
噢噢噢
到了大家最关系的价格部分喽
上图以国际拍卖克拉单价记录为例
列举的红宝石、蓝宝石的价格差异
图1是红宝和彩蓝宝拍卖记录差异
图2是1979-2015年红宝石拍卖记录
图3是1979-2015年蓝宝石拍卖记录
大家可以看到
拍卖记录的价格逐年攀升
红宝石的价格远超蓝宝石
虽然红宝石高达120万美元/克拉
但红钻能达到500万+美元/克拉
