The images don't do the stones justice.. although the lighting is acceptable, you're attempting to get to close to the subject.. I guess I'll have to write a few photo techniques and post them in a few days. keep trying, just don't try too hard. I think you can do better with the images.. see what natural sunlight can offer you.
Yes.. much. Thank you. I still don't see any clear evidence that you have any turquoise.. However as I stated above.. you have a nice treasure trove of Amazonte and a couple of pale Emeralds. Search for these images online and compare. Yes Amazonite can have cubic features.
