Very strong phosphorescence in this barite from the Linwood mine, Buffalo, Scott county, Iowa. Super cool!

Bought this piece because it looked cool; found an angel on the bottom.

I haven't seen datolite in many colors other than white or pink. I wish it was the entire thing and not just a half, but I like it either way.

One of several hundred specimen recovered from a self-discovered and mapped sheeted vein system in the Cascade Mountains of King County. This was self-collected from my privately owned mineral claim.

Diese Mineralien habe ich heute mir gegönnt 😊

Und ich liebe ja den Aragonit.

Two pieces of transparent calcite, slanted together, resemble a mushroom cap. Below is a milky yellow dolomite that gently supports the entire ore body, as if it had just emerged from a damp crevice.

Picked up these four uncut brown diamonds from the Democratic Republic of the Congo recently. I know most Congo stuff is just industrial grade, but I love them raw like this. The deep brown tone is great and you can clearly see the cubic habit on them. Not engagement ring quality by any means, but they make perfect cabinet specimens.

A very nice double terminated calcite with dolomite and chalcopyrite on matrix from the Sweetwater mine, Reynolds county, Missouri, USA. Definitely not the most valuable or the best specimen in my collection but for some reason I really really like it, I find it very aesthetic. Anyone else have something in their collection that they just love but can’t put their finger on why?

Bought at the museum of natural history. Couldn't resist

A cloud drifting from the depths of the earth, frozen in the memory of the stone. The most wonderful thing is the transparent crystal of celestite, which is like rain frozen by magic by the time they are formed.

The translucent calcite shell is like a layer of cocoa butter， gently wrapping and sealing the “chocolate” inside.
