I do enjoy a nice diaspore. It's an unusual (and certainly overhyped) but oddly attractive gem.

Yeah, I bought a faceted stone some years ago. Bug juice at best. Not my favorite.

I'd prefer to think of it as bug juice at its best :D

I am so sorry that you spend some money for this "gem" :roll:

Hope not to much...

I've spent a lot of money just to have something in my collection.
But, you're right Marlow. It's not something I take out to look at very often.

It's pretty easy to get smaller ones on the cheap (and I do mean The Cheap) if you are patient. As long as you aren't paying Fine Gemme prices for it it really is a lovely little curiosity. It's easy to appreciate a peacock blue sapphire; anyone off the street can do that. To love the more unusual, unique color ranges requires either broad tastes and a deep appreciation of gems and minerals or a suite of TV cameras, an audience of millions and a salary that depends on it.



(I do love these oddball stones, though--if you pair them up with the right stone they can look very nice in jewelry. Axinite for instance can really shine when you have something else to help emphasize one particular color in it).

From mr 'show & tell', I agree the material is a bug juice type of item, this stuff is said to be a single source stone, very hard to mine, even harder to cut for clean material, color change is not guaranteed but there are a small group of 'red carpet' stars who want to be unique in the lights and are asking to wear this stuff. Prices are high for the good color change stones but the market is not supplying the demand. The stone I have is a good example of cc diaspore, shown in daylight & candlelight-steve... 8)

Diaspore's CC is subtle to put it nicely. I don't know if it would be possible to actually capture it in a picture without some sort of shenanigans with white balance or what have you.

Forum, how about this picture, incandescent light, no background! this pic was shot in a dark room with the light as the only source, the pastel rose color comes out pretty nice?-steve... 8) I added a 2nd pic, also shot same, no added or tricks, just the light & tripod...

I don't think that's pleochroism we're seeing.
