A kyanite specimen made of fanned crystals, colored with a thin layer of something, maybe gold, to make it iridescent.

A large piece of chalcopyrite showing silver colouring as well as teals, blues, and purples.

A roughly teardrop shaped opal that is reddish with brilliant flecks of greens, blues and reds.

A small rounded triangle of fire agate, filled with small rounded segments that flash a rainbow of colours in direct light.

Seems like kind of a niche hobby on bluesky so far, but I made a feed for my mineral collection.

Here's a few of my more colourful specimens!
