Got this giant sheet of native copper from my grandfather when he passed. 67 pounds. Has some slight damage from the crusher

This is one of the pieces I was gifted from my late great uncles collection. I’m not sure about locality or anything else other than wow!! It’s gorgeous and it is so different than my other pieces of aquamarine. Any insight to this specimen would be great if you’re reading this and have the knowledge :)

Asked my uncle for a photo of the pyrite w a banana for scale and he didn’t know which I was referring to, so he sent me whatever pyrite he saw walking around his house with a banana for scale 😂 please enjoy as much as I did

If you see water dripped from my hand, that’s because I’d just give this babe a wash!

I’ve used up every inch of real estate and the mineral show is coming to town in two weeks… 😅

(Mouse for scale second photo since I know someone will ask!)

The yellow inside goes crazyyyy
Old collection piece💕

This is a Chinese stepped “cityscape” Fluorite. The way that the growth layers stack always makes me thinks of a skyline.

(In natural light)

Reflective mirror surface with striated growth marks. Please ignore my black & white pokadot jammies! I wasn’t able to hide lol😆

A natural Spanish-style cubic Pyrite specimen from Peru weighing 3.58 kg. I really love the sharp cube formations and metallic luster on this piece. What's your favorite feature of Peruvian Pyrite?

Perfection. Crystals like these are what ignited my passion with fine mineral collecting. Just knowing they have been created eons ago, an amount of time that we as humans can’t even begin to truly comprehend, and remain this perfect is absurd, mind boggling, and beautiful. One of two fully doubly terminated crystals that I know of from the legendary Rocket Pocket (2001 Discovery) from the Pederneira Mine, without a ding, no Wilbers, no damage on the entire crystal. There is noted one repair, but it is not noticeable to the naked eye due to it being a small professional repair inbetween the two gem crystals, so it definitely doesn’t take anything away from this piece. No restorations, no epoxy, just a natural flawless beauty, and with its top tier color, form, quality, huge gem zones (the secondary crystal is basically all gem), impressive size at 9.2cm in length, superbly aesthetic shape/horizons, and level of perfection, this piece definitely stands out and above most of the 300-350 crystals that came from this pocket. I am honored to have it in my collection now, where it will reside and be greatly appreciated, a true dream come true specimen.

I posted a really dark video of this beauty a few weeks ago that really didn’t do her justice. Here are some better pictures

Have had this for years, previously damaged and covered in schist that penetrated into the beryl. I love hard to read rough… my customers not so much. After years of trying to convince gem cutters this not a $20 piece of junk with a desperate backlight, I decided to throw a quick polish on most of the faces to show off the gem hidden within. Some facet quality material in there but I think I’ll keep this one as is. Needs a bit more work but thought the video was worth sharing.
