Beautiful saccharoid quartz geodes with brilliant crystals.
The price shown includes both parts of the geode.
Geodes are spherical or ellipsoidal cavities formed in the rocks in which some mineral has precipitated, forming sheets of crystals (quartz) or concentric bands (agate).
The piece you receive may differ slightly from the photo shown as the minerals are natural and no piece is identical. The size is approximate.
