How I can differentiate between obsidian and onyx accounts / cards?
Is there any evidence that I can do to know if black mineral chips that I have to make jewelry are of obsidian or onyx? Or any easy way to tell the difference? Thanks!
<> Probably the best way specific gravity would be … let me see if I can get more information … There seems to be differences in both specific gravity and hardness. Have no gemological knowledge, I'm not sure how to measure these and the sites I looked at do not give much information. I did, however, find this woman who seems to know their stuff … maybe she can help you: http://www.acstones.com/askbarbara.html
