Oh, that’s a very good question! Here are some suggestions:

“Identifying Precious and Semi-Precious Gemstones” (web page), from the

Mineralogical Association of Canada

“Gemstone Identification” (PDF document), by Larry Zvolensky and Tim Specht of Naturichards, who offer online gem testing services

“Determining the origin of non-precious gemstones (Nongems)” (PDF document), by

Thank you for the information. Do you know what characteristics are used to identify gems?

I don’t really know much about it, sorry.  I can tell you that in the US, the US Customs and Border Protection website has a page titled “Identifying Diamond and Jewelry Gems” that you can look at for general information on characteristics of gems and stones.

Okay. Do you know how I distinguish gems based on color?

That’s a good question, maybe something about that information is in that US Customs and Border Protection document?  I don’t know of any easy rules of thumb
