The amethyst quartz specimens from this old Murcia mine are highly prized among collectors. In this specimen, we can see various doubly terminated quartz crystals, with the amethyst color showing some zoning, more intense at the tips. The luster is very good. 615h52
Group of galena crystals with very rounded cube-ocathedral shapes and dotted with numerous brilliant sphalerite crystals with hexagonal very rare shape. Very curious.
