Rutilated Quartz
A variety of Quartz
What is Rutilated Quartz?
Rutilated Quartz is a species of quartz, generally gold but occasionally silvery, coppery, or even black. Every individual stone has a unique pattern. While inclusions usually lower the value of a gemstone, rutilated Quartz is an exception in this regard; the imperfections add to its desirability and consequent value.

Health & Safety Information
- ⚠️Harm Reason: Rutilated Quartz in powdered form can be toxic due to its Crystalline Silica content.
- ⚠️Physical Toxicity: Quartz, silica, crystalline silica and flint are non-toxic materials, but very fine dust containing quartz, known as respirable crystalline silicon (RCS), can cause serious and fatal lung disease. Lapidaries should exercise caution when cutting silica.
