Snowflake Obsidian Rings
Obsidian is lava that has
cooled too rapidly for crystallization to occur. It is not a true mineral but is
sometimes classified as mineraloid. It has a smooth, glassy appearance and the
fracture edges are extremely sharp. Obsidian consists of at least 70 percent
silicon dioxide (SO2) but impurities can create a wide range of color and visual
effects. The "snowflakes" can be more accurately described as small inclusions of
radially clustered crystals of cristobalite, a polymorph of quartz and
tridymite.

Commercially cut 10x12 oval set in a fine silver bezel cup and mounted on a size 6½ hammered sterling silver band. I
usually have a few of these laying around the shop, so ask me if you need a different size.
