Jet (Ignite) Black Amber

View our range of beautifully handcrafted jet (ignite) black amber gemstone jewellery.

Jet is a geological material and is considered to be a minor gemstone. Jet is not considered a true mineral, but rather a mineraloid as it has an organic origin, being derived from decaying wood under extreme pressure. The English noun "jet" derives from the French word for the same material: jaiet.[1] Jet is either black or dark brown, but may contain pyrite inclusions,[2] which are of brassy colour and metallic lustre. The adjective "jet-black", meaning as dark a black as possible, derives from this material.
