Nice fluorite specimen, Mike!
My first thought was rather Surprise Mine / New Mexico, I've never seen something like that from Naica. But I know there are many different kinds of fluorite from Naica so I won't doubt that locality information.
I love the zoning inside of the crystals!

Regards
Tobi


The specimen came from an Australian collector. He didn't have the original label just his own label. The collection was amassed during the late 70's early 80's. The dealer was a little surprised at the locality. I think that you are correct and that it is from New Mexico not Naica. Looks a lot like this specimen:

I too was a little surprised at the locality stated for the piece.

Hi Mike,

Your recent fluorite is definitely from the Pine Canyon Deposit, New Mexico. It's similar to the Surprise mine material, but it has the rounded faces and more clear outer layer than what is usually found from the Surprise mine. It's also definitely not from Naica.

Between 4-5 mm for the crystal in the foreground and 3-4 mm for the one in the back.

I think I have never seen emerald together with fluorite. A wonderful combination of two great minerals!

Thanks Tobi! I had the same thought when I saw the specimen.
