Agate / Crystal Geode

Tan and grey rings frame a violet pocket with a dash of gold.

This is an agate and crystal geode. A geode is a hollow rock lined with mineral crystals, and it forms when mineral-bearing water slowly deposits material inside a cavity over a very long time. Couple of rounded, slightly triangular halves with a brown outer band and pale inner ring. Dark purple points fill each cavity, while small golden flecks show in the lower corner of both. The crust is rough. It is 5 inches wide, 5 deep and 3.25 high.

A small treasure box with a glint at the hinge.
