Sphalerite and quartz cluster crystal from Bulgaria 198g

A natural sphalerite and quartz cluster from Bulgaria, measuring 105x68x29mm and weighing 198g. The piece shows sphalerite crystals with a characteristic resinous to sub-metallic luster in grey tones, growing alongside white to translucent quartz crystals on a shared matrix. The flat, elongated form of this specimen gives good display of both mineral species side by side.

A clean example of the sphalerite-quartz pairing typical of Bulgarian ore deposit specimens. Natural sphalerite specimen Bulgaria, quartz and sphalerite cluster, raw sphalerite crystal, Bulgarian sulfide mineral, sphalerite display piece, mineral collection Bulgaria, untreated natural specimen.
