Black Obsidian Crystal Beaded Necklace

Black Obsidian

Obsidian is the name given to volcanic glass – a rock rather than a mineral, it is a mixture of cryptocrystalline grains of silica minerals in a glass-like suspension and displays a conchoidal fracture. Obsidian forms during the last stage of volcanic activity, close to the earths surface cooling occurs too quickly for crystals to grow. Natural obsidian varieties include black, bluish, mahogany, gold & silver sheen, rainbow, etc. – the colors due largely to refraction by microscopic bubbles (and microscopic mineral inclusions such as magnetite in “Rainbow Obsidian”). Lustre: Vitreous

These necklaces are deisgned to be both practical and beautiful.

Each individual faceted crystal is carefully drilled and then beaded on an 18 inch stainless steel cable with a nylon overlay.

With a  base metal clasp and a 5cm extension chain, it enables the wearer to lengthen the chain slightly.
