Are the rubies in this collection heated?

Each listing states whether the stone is heated. Where the stone's laboratory report carries a treatment entry, we give it exactly as printed.

Where do these rubies come from?

Each listing states it. Where a GIA report gives a geographic origin, we print it with GIA's caveat that any statement on geographic origin is an expert opinion. Where a stone's report gives no origin opinion, the listing says so, and any origin we name is our own sourcing record, not a laboratory finding.

How can I check a ruby's laboratory report?

Where a stone has a GIA report, its number is on the listing and can be checked on GIA's own Report Check service at reportcheck.gia.edu. Ask us for anything else you want to see before you buy.

红宝石裸石

关于红宝石

红宝石是红色的刚玉，与蓝宝石同属一个矿物种，红色主要来自微量的铬。本系列的红宝石均以裸石出售，可交由您的珠宝师镶嵌成戒指或吊坠；设计镶座时请以该颗宝石页面上的尺寸为准。颜色偏粉的刚玉请浏览粉色蓝宝石，或浏览全部宝石。

每件商品页面列明的内容

本系列每颗宝石单独上架，附有该宝石本身的照片和视频，以及检测报告所载的重量、尺寸、形状、切工和颜色等资料。每件商品页面注明该宝石是否经过加热；若检测报告载有处理项，我们按报告原文照录。价值较高的宝石附有美国宝石研究院（GIA）报告，商品页面列出报告编号；由其他实验室出具的报告，页面会注明实验室名称。

产地与采购

Crescent Gems 自2000年起在斯里兰卡采购宝石，大部分由自家工坊切磨。商品页面所列产地，若来自GIA产地报告，即为实验室的专家意见；如报告未载产地意见，页面所列产地是我们自己的采购记录，并非实验室结论。
