Rutilated Quartz is found predominantly in Brazil and is characterized by its hair or needle like inclusions within the Quartz. There are a large number of varieties of this with the needles being coloured either silver, gold, copper, or black. The density or positioning is always different so no two pieces are the same. Sometimes if the needles are in the right combination of density and location they can form a cats-eye effect. Depending on its transparency it can be either cabbed or faceted. |
