Tinzenite
Tinzenite is named after its discovery locality, at Tinzen, Grischun, Switzerland.
Tinzenite forms transparent to translucent yellow, brownish yellow-green, orange, red prismatic crystals to 5 mm or masses with vitreous lustre.
Tinzenite makes attractive faceted stones that can be used in the jewellery.
