Interesting color in this, like aquamarine. The lighter pic of just a slab is in natural light, the warmer color one is a compact florescent bulb. I found this in the mountains west of me where I stopped to eat a cookie, there was a string of opaque white quartz crystals in a row and then down at my feet this one, I couldn't tell if the color was from moss or not but I had my hammer and popped it off and stuck it in my pack, finally got around to messing with it.

Curious one. A hardness test would help to know if it is quartz/feldspar hard, calcite/fluorite soft, or somewhere in the middle like apatite. Appears to break (cleave) like feldspar.

I sawed it with my 10" and you can see how fractured it is, it's a mess not sure I'll be able to make anything with it.

The last image may be overexposed? There is nothing black in the pic. Can we see an image looking at the point of the big one?

It's more clear than the chunk of amazonite I have, here's a few more pics, side by side w/amazonite and a close up of it all lit up with a white LED. Cool rock eh?

Amazonite has grades. Not all are same quality.

Here's a view looking down on the point:

Here's the area and what's usually found over there: www.mindat.org/loc-8251.html

What wavelength UV light do you have?
