Is this Selenite?

0 votes

I have taken a few pics of a large piece that we have. We found it and don't know who it belonged to, probably my MIL or FIL. Is this selenite? or Kernite?alt text

took more pics of a piece I broke off and it doesn't bend. Breaks into spears/splinters/blades. Will post pics below of chunk, a piece of crystal and the blade I broke off.

Doesnt look like Kernite. Are the fibers able to be bent? If so it would be selenite. May also be calcite.

no, fibers cannot be bent, they break off easily, most of the time

This is not selenite, as selenite fibers are much thinner. Can you push your fingernail in the stone?

I think it is a nice piece of rock crystal.

The last pic and this one show a small blade broken off the big chunk, not bendable, and with a rock crystal that we have, for comparison.

If its calcite - here is a way to test it. See if you can get a hold of a strong acid - such as lime out (you can get this in most hardware and home supply stores). Them apply a dab of it to the stone and see if it bubbles up (effervesces).

Maybe it is anhydrite?

It could be Satin Spar Calcite
