PostPosted: Jun 03, 2019 07:52    Post subject: Help identify transparent green mineral.  

Hi, I found this in Tenerife about 30 years ago, and just rediscovered it during a clearout.
I vaguely remember finding it while doing some snorkelling in an extinct caldera.
I don't have the knowledge to test it (at the moment), so any info would be good.
Sorry for slight blur on the lit image, I have very shaky hands.
Thanks. :)

James,

The pitted and bubble like areas on the surface suggest glass or slag glass. Bob

I actually didn't notice the bubbles until I posted the images on here and saw them on a big screen.
Glass would seem to be likely. Still pretty though, and a nice childhood memory.
