注意事项
请谨慎购买,以防买到仿造的宝玉石,如合
成立方氧化锆、合成碳硅石、人造金红石、钛酸
锶、无色托帕石、无色蓝宝石等。通过拿宝石去划
玻璃来辨别真假的做法是没有意义的,因为仿造的
宝石由于硬度高的原因同样的也可以划开玻璃,最
好是找到专业研究宝玉石的人士做一个详细的真假
辨别。如果您正要在一块大的宝玉石上面做巨额投
资,请在购买前先获取钻石的鉴定分级证书,且此
保证书必须由权威性的部门开出。
Reminder
Be aware of numerous imitations of diamonds: cubic zirconia,
synthetic moissianite, synthetic rutile, strontium titanate, colorless topaz,
colorless sapphire, and many others. Scratching glass is a useless test
as many imitations also scratch glass. Consult a professional, independent
retail jeweler to insure you are getting the real thing.
If you are making a large investment in a diamond, make sure
that you are getting a diamond grading report from a reputable gemological
laboratory.
