Smoky Quartz

This caboson oval shaped smoky quartz from Brazil ranges in size from 15.80x12.00 mm to 16.00x12.20 mm and weighs between 8.90 and 12.25 carats. Characterized by its excellent clarity with no visible inclusions, this treated specimen maintains a uniform dark brown hue. The cabochon shape, with its smooth, domed surface, enhances the stone's depth and brilliance, making it ideal for use in fine jewelry such as rings, pendants and brooches. Smoky quartz adds a touch of sobriety and sophistication, combining an elegant look with a high-quality finish.

The chemical composition of smoky quartz is silicon dioxide (SiO₂). Treated smoky quartz is predominantly mined in Brazil, recognized for the superior quality of its quartz crystals. Other notable extraction regions include Switzerland (Swiss Alps), Madagascar and the United States (Colorado).
