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

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.
