Helvine included in Quartz (rare)

Item Description

RARE, rich phantoms of bright yellow Helvine microcrystals are clearly visible within the sharp water-clear termination of this complete all-around quartz crystal from the famous Yaogangxian Mine. The quartz crystal is transparent to translucent with both glass-clear and satin luster faces. Helvine is a Be-Mn-silicate with sulfur and is found in granites, pegmatites, gneisses, contact zones and skarns (MINDAT). Contacts on two sides of the quartz and a bit of edge bruising hardly matter, as this specimen is not about the quartz quality, except for the termination clarity which permits a really good view of the helvine phantoms through three termination faces. A rich and rare combination rarity from the locale from small finds in 2020.
