Negative crystal in spinel
Vietnam
Field of view = 2.9mm • Depth of field = 0.85mm

It's not uncommon for spinel to form negative crystals within, but this is one of the most shockingly perfect negative crystals I have come across. The way the light races across its terminations and ghosts the inner cavity with a confusion of color makes this negative space one of the most exciting pieces in my collection.
