Haüyne is a rare gemstone which famously comes in gem quality from an extinct volcano from primeval times in the Eifel Mountains. The haüyne occurs just in a small ring around the volcano in certainly distance in reach of crater. The ring of haüyne is now totally mined and exhausted. They wont be considerable discoveries in the future, so these offered haüynes will become very rare.
