Hedyphane is named from the Greek which is loosely translated as "pleasant appearance". It was first described from the famous Langban Mine in Varmland, Sweden where many unique and exotic minerals have been found. Hedyphane is one of the uncommon members of the Apatite Group of minerals; whose members include the much more common apatites, vanadinite, pyromorphite and mimetite.


  • Color is typically white, gray, bluish or yellowish, but can also be red-violet and green.
