[QUOTE="Brumble-Gum, post: 418807, member: 1569"] I have tried this test and it appears that this is double refracted. It is a little hard with the green "knobby" bit sticking out and it is not clear as the ones on the website. But you can see that words are blurred under it. I need to have this cut with a lap saw to remove the knobby bit. As for the rock hardness, it is not soft at all. It is quite hard, I actually had to use a bit of granite to remove the calcite (or whatever) from its origin. Both green and white/clear are about as hard as quartz crystals. [/QUOTE]
