Auro & Co Moment

The appeal of a geode is partly the contrast between the rough, unremarkable outer rock and the crystal interior. The black exterior of this piece makes that contrast particularly sharp. It reads as a plain rock until displayed open, at which point the purple interior is the entire point.

Pairs naturally with a crystal cluster, an amethyst tumble stone, or a wooden display stand.

FAQ

Is the colour natural?
No. The purple colour is artificially enhanced through a dyeing process. The calcite crystal formation and geode structure are natural.
