Colombianite Silver Pendant Necklace

A very deep green toned Colombianite which has been free form hand cut by ourselves and set in a copper & fine silver formed textured setting for an unusual, more organic look. 

The pendant is approximately 2.4 x 1.3 cms at its widest points and is hung on an 18” sterling silver rhodium plated chain. 

Colombianite, also known as Piedra Rayo, is a form of Obsidian glass that closely resembles a Tektite (Hence its Pseudotektite classification). Piedra Rayo translates to “Lightning Stone '' and is believed to have been the “Cintamani Stone” from sanskrit teachings and literature. It was estimated that these stones are around 30 million years old. Most Colombianite forms in small ovals and spheres with irregular grooves along the outside that look nearly identical to the “hedgehog” makeup of Moldavite. Upon first glance, you may think that this is a solid, bold stone that is unable to be penetrated by light. However, shining a light through Colombianite will result in the black exterior being overwhelmed by a smoky or yellow transparent color that shines through. Pieces are generally sold by the gram due to their rarity and can usually range from a quarter-inch in size to up to a few inches. Local villagers and tribespeople make a living by hand mining these pieces. There are only a few known deposits in regions of Colombia coming out of the area of Cauca
