Black Quartz Cluster
A black quartz cluster features several terminated points which have grown in every direction. Ranging from a few millimetres in size up to four centimetres, they're mostly tranlucent and all have a vitreous lustre.
Quartz is one of the most common minerals on Earth yet clusters of terminated points like this continue to amaze and fascinate us. This impressive black quartz mineral specimen comes from the Ouachita (wosh-i-taw) and Ozark mountains which stretch from West Central Arkansas to Southeastern Texas in the United States. The rock matrix on the underside of this quartz cluster is absolutely full of minute sparkling crystals.
