I've read through Jeff Graham's article here on apache tears and the other articles about glass/obsidian and the troubles with faceting, but I couldn't find a good answer to my question. For some reason, I'm not able to view the gem price guide to see obsidian prices (I've emailed support).
An inlaw gifted me a box of rocks and in it was about 20 apache tears ranging in size from about 1/2 inch to 1 inch, mostly round. All are quite translucent gray and some slightly smokey when under light but black in appearance otherwise. I've tried to attach a pic here.
I don't know what to do with these so I was wondering, are they more valuable to leave as-is, or do I risk trying to facet some of them? I would hate to end up destroying them if they have some measure of value or rarity as-is. I just don't know what people do with apache tears and they look pretty translucent to me - some have more bubbles than others. I've faceted man-made glass before without issues but that glass didn't really have bubbles or other inconsistencies in it like some of these apache tears do.
I'd appreciate your opinions and suggestions.
