Prehinite on trap-rock, Fredda. Probably from the N. Va quarries.

Thanks, guys. Wondering just what might be done with the prehinite part of that rock?

FYI--this should be spelled--prehnite. No wonder I couldn't find it.
fredda ;D

I have seen it cabbed. Yours definitely has a very nice color to it.

Fredda,
Most prehnite can be cabbed fairly easily and I have seen it advertised in faceted form but I think it would have to be much thicker than your piece for faceting. (Maybe cabbed with faceted top would work?) I have done the cabbing, it takes a decent polish and ends up looking sorta like pale jade. If the gemmy part is too thin, I have actually left a thin layer of the host rock to back it, rather like a natural doublet. It makes the cab much heavier but I figured better that than have the prehnite break apart. Hope this helps.

Fredda, Another idea, of course happening AFTER I hit the send button for my previous note.  I have seen some beautiful "cabs" with Drusy tops and your picture seems to show tiny crystals all over the place. Perhaps just cut out the shape(s) you want, touch up the edges a bit and leave the Drusy tops totally natural. Either set in a traditional bezel or perhaps wire-wrap it. With the nice color in your specimen, I bet that would turn out REALLY nice. Take care. |

Hi Emerald. I appreciate your suggestions. I'll be saving them for later as my rock stuff is packed for moving. Thanks. Kilrush-- You are not alone, heh, heh.  |
