Agate / Crystal Geode

Deep plum rings and a glassy white heart, one half tall and stubby.

This is an agate and crystal geode. Agate is a banded variety of chalcedony, a microcrystalline form of quartz, and its layers often appear in bands of white, gray, blue or brown. Pair of halves with dark purple-grey bands, a thin ivory line and a pale smooth cavity. One half is broad and ochre-edged, the other narrower and tilted forward. The outer rind is tan and rough. It is 5.25 inches wide, 4.5 deep and 3.75 high.

Handsome, a little lopsided, and entirely unbothered.
