Colombianite
Columbianite is a volcanic glass - similar to obsidian, formed by the rapid cooling of molten lava on the Earth's surface. Its unique chemical composition and structure give it its characteristic appearance and properties. Columbianite is known for its translucent colour, which is tinted in grey-brown shades due to the presence of various minerals during its formation. Its surface is pitted, caused by the action of soil acids, similarly to Moldavites. Columbianite is often sought after for its beauty and exotic origins, making it a prized material for jewellery making and collecting. With columbianite, you acquire a unique piece of nature for your stone collection that impresses with its appearance and origin.
