3.5" Rutilated Smoky Quartz Crystal Cluster - Brazil

This is a rutilated smoky quartz crystal cluster that was collected from Brazil. It measures 3.5" wide and contains sprays of golden rutile throughout the specimen. There is a botryoidal mineral on what could be considered the back of the cluster, likely goethite.

Rutilated quartz is a form of quartz that is characterized by needle-like inclusions of rutile within the structure of the quartz crystal. These inclusions mostly look golden, but they also can look silver, copper red or deep black.

Rutile is a titanium dioxide mineral, and sometimes contains large quantities of iron oxide.

Smoky quartz is a grey-brown to black variety of quartz. This common name is derived from from the appearance of smoke within the quartz crystal. Dependent on the location and the chemicals present during formation, smoky quartz can appear opaque black, however it’s typically translucent to some extent. It’s believed that the quartz gains this color from a combination of natural irradiation and aluminum impurities.
