Smoky Quartz

This dark brown rectangular shaped natural quartz, originally from Brazil, ranges in size from 7.80x5.80 mm to 8.10x6.10 mm, and weighs between 1.40 and 1.70 carats. With clarity without visible inclusions and treatment applied to accentuate the color, this specimen retains a deep and uniform dark brown hue. The rectangular shape and finish make this quartz suitable for use in understated and elegant jewelry, such as rings and pendants, lending a contemporary and refined look. Dark brown quartz provides a great visual contrast, emphasizing a modern and sophisticated design.

The chemical composition of quartz is silicon dioxide (SiO₂). This type of treated quartz is predominantly mined in Brazil, recognized for its high-quality quartz deposits. Other important extraction locations include Madagascar, Switzerland (Swiss Alps) and the United States (Colorado).
