A beautiful specimen of canary-yellow ettringite crystals growing on a small base from the famous NChwaning Mines, South Africa. It comes from the collection of Stephen J. Gerome, MA, USA, with a label. It features well shaped hexagonal ettringite crystals to 13mm. They are matt with a rich color. Colorless calcite crystals are seen too. The main ettringite crystal forms an excellent focal point. In very good condition – some small contacts. On acrylic base.

Aesthetic ettringite!
