Chinese Bangle

Deep forest green with swirls of lighter green running through like a pond at dusk.

This agate bangle is from China. Agate is a banded form of chalcedony, a fine-grained quartz, and its layers formed as silica was deposited in cavities in rock. Wide, shallow bangle in glossy dark green with streaks and swirling bands of lighter green and yellow. The inside and outside are smooth and mirror-bright, and the edges are softly rounded. It is 0.5 inches high and 3 in diameter.

Glossy, swirled, and dignified as a pond.
