Frequently Asked Questions

How do I identify laboratory-grown diamonds?


Because laboratory-grown diamonds are essentially chemically and optically the same as natural diamonds, traditional gemological observations and instrumentation are not able to tell them apart. GIA uses sophisticated devices like the GIA iD100® and other instrumentation to definitively identify natural diamonds. To confirm whether a diamond is natural or laboratory-grown, send it to a gemological laboratory for examination and advanced testing.
