Answer:
This one only test for metal,and diamonds and moissanite,and I like it and it's very accurate,the tool for gemstone it's a refractometer,and a spectrometer,and I have both,and they are very hard to use at least for me,I've been collecting stones for at least 15 years,and most of the time I can recognize them without any tools,even the most exotic ones,I'll be honest with you I am way more lost with the tools,but you can buy them and judge for yourself,but there is no tool like this one to test gemstones,I wish that was,because it would make life easier on everybody.You can also buy books on gemstones with pictures,that helps a lot to give you a general idea of what they look like.Hope this help.
