@MineralCup@mastodon.social Graphite is a workhorse compared to the flashy pyromorphite, but it sometimes shows it's more picturesque side. First image, graphite crystals from Sterling Hill, NJ (photo Michigan Technological University). Second image crystals on matrix from Olmsteadville, NY (photo from Well Arranged Molecules). The second specimen is currently available for purchase.
