Hi everyone, I picked this up a few weeks ago because I really liked the interesting inclusions that I haven't seen before. The crystal itself is super clear but has a slight tint to it, with what looks like a hairline at the very bottom that's hard to see. The inclusions are a metallic shard that's quite shiny and iridescent, and a blood-colored phantom (it really looks like blood from a fresh cut). Could anyone help me identify what the inclusions might be? I did a bit of searching and I think Hematite also has this red coloring but it seems like it usually appears and little dots rather than in this manner?
A striking piece of lapidary work! As Reiner says, it looks like hematite (both the metallic base and the red inclusions) and quartz, although there are lots of other possibilities for the metallic part. Hematite inclusions in chalcedony often appear as little balls or dots, but continuous red films as you see in this piece certainly can result where iron-bearing solutions have seeped into fractures.
