Excellent and aesthetic small galena crystals on quartz base and with singenetically developed black sphalerite-marmatite crystals. Galena is presented by well developed shiny galena crystals, some of them with pseudohexagonal symmetry, typical for galena crystals, twined in spinel law twin. Galena is with rounded edges most likely result of dissolvation.
Funny specimen showing two calcite and quartz covered calcite scalenohedral crystals twined in „fishtail“ law, developed on quartz crystals and looking like one of them is trying to swallow the other
Very well developed floater formed by group of pseudohexagonal galena crystals, due to twining in Spinel law twin.
A spectacular specimen of transparent quartz on the mother rock with very large for Bulgaria clearly displeyed Japanese law twin.
Small qartz crystalz on the matrix. Almost every one of them is twined fallowing Japanese law . Some of nthe twins has joined their corners forming something like „buterfly“
Perfectly situated Japanes law twin in transparent quartz on the matrix
