Some stuff I dug out of a mine here in Southern Nevada a few years ago. Unfortunately, this mine and another mine I used to find turquoise at have been taken over by gun ranges. This is naturally hard and none of this has been stabilized and does not need to be.    |

A number of years ago I purchased a lot of chrysocolla from a guy in AZ that was mining it.
Interesting, as so many different colors in this same batch
We slabbed some of the other day & one of the pieces had this beautiful spiderweb veins.
This particular one is quite soft and so I stabilized it.

This was one of my favorite pieces from here in Southern Nevada. It was about 4 inches long until a lady wanted to see what it would look like a bracelet. She put it on her wrist and it slipped off and fell on a tile floor breaking in to multiple pieces.  |

The differentiation between turquo0ise, phosphosiderite, variscite, chrsocolla, and various other gemstones in the phosphate/copper series requires laboratory analysis. It's not a "sight" ID. Some of the so-called Hubei "turquoise" from China looks identical to Nevada variscite/phosphosiderite. Some American stones identified as Turquoise seem to me to need lab ID. Here's one I love and have puzzled over for a long time and can't ID opmpletely other than the chrysocolla component. Those copper minerals love to "mix it up." This stone is hard, close to quartz. It took a brilliant polish at 8K.  |

True though that a lot of the minerals are hard to ID by site. Variscite you can use a chelsea filter for though to determine if it has chromium.

You have some SWEET material and to think you and Jax hounded it all yourself. Good deal! |

I think it's almost becomes overwhelming vegasjames , looking at all the different flavors & colors of turquoise you have. Really over the top, when as Tela mentioned, that you've hounded it all - thanks for showing it & naming them.

Do you happen to have a larger version of this? I downloaded it for reference, but it's a little small. If you do, you can PM it to me, if you want to. |
