I bought a lot of Prehnite; almost half was dime size or smaller so I decided to tumble a batch.
This stuff was a challenge. After about 2 days it was real foamy and after the third day I couldn't hear the rocks tumbling. Two times I scooped out think foam and added water. Then I added borax and rock salt. That helped, but still foamy. It took about 2 months from start to finish. The AO wasn't two foamy but I let it roll for about 2 and half weeks.
The color ranged from a yellow to a mint green. The black stuff was a mineral called epidote
Some pieces really let the sun in and have a cool "glow". These seem big enough to have faceted. Anyone do faceting? send me a pm. I got these and some bigger pieces that look pretty clean.
Enjoy; any advice on the foamy stuff feel free to post.
