2" Polished Snowflake Obsidian Sphere - Utah

This is a 2" wide, polished sphere made from snowflake obsidian collected near Sevier Lake in Millard County, Utah. Nice polishing work on this piece and it comes with the pictured display stand.

Snowflake obsidian is found near Sevier Lake in Millard County, Utah. It is a natural volcanic "glass" that forms when molten rock cools so quickly that that atoms do not have enough time to arrange themselves into crystals. Instead, the molten material solidifies into an amorphous solid called a glass. The "snowflakes" in the obsidian are small, white, radially clustered crystals of cristobalite, a mineral polymorph of silica.

Obsidian was important material for many ancient people. It was used for making tools, weapons, jewelry, and decorative items, and was a major barter material for Native Americans. When broken, its conchoidal fracturing results in extremely sharp edges, making it ideal for knives, scrapers, arrowheads and spearpoints. It is even occasionally used today to produce surgeons' scalpels, since the edges are several times sharper (only 3 nanometers) than the edges of steel blades.
