3D3DHigh purity crystals. (External Sample)
These are industrially produced high-purity calcium crystals of the highest grade. They are shiny, soft enough to tear apart by hand, and sealed in a glass ampule because they would react with air and tarnish within seconds. Unfortunately I cannot reveal their location as the company that makes and uses them in their work is very sensitive about trade secrets: I had them on loan for a few weeks to photograph for a film project, then sadly they were destined to be turned into something quite a bit less beautiful.
