Gemological overview

Technical and gemological information about this gemstone variety.

Gemological profile

Quartz is one of the most abundant and widely distributed minerals on Earth, valued in gem-quality form for its clarity, durability, and broad range of appearances. As a gemstone group, quartz encompasses many well-known varieties, as well as colorless and subtly toned material appreciated for its clean, understated character.
Chemically composed of silicon dioxide (SiO₂), quartz crystallizes in the trigonal crystal system and belongs to the silicate mineral group. In gem-quality specimens, it typically displays a vitreous luster with transparent to translucent clarity.
The refractive index of quartz generally ranges from 1.544 to 1.553, resulting in a soft, even brilliance rather than strong dispersion. Quartz is found worldwide, with notable sources including Brazil, Madagascar, Switzerland, the United States, and many other regions, reflecting its widespread geological occurrence.

Durability & suitability

With a hardness of 7 on the Mohs scale, quartz offers good durability suitable for everyday jewelry when properly set and worn with standard care. Its resistance to scratching and lack of cleavage contribute to reliable performance across a wide range of jewelry designs.
Quartz performs well in rings, pendants, earrings, and bracelets, particularly in settings that balance exposure with protection. Its durability, availability in larger sizes, and neutral visual character make quartz a versatile choice for both everyday jewelry and minimalist, design-focused pieces.

Treatments & authenticity

Quartz is commonly found in nature without the need for enhancement. Depending on the variety, treatments such as heat treatment or irradiation may be applied to modify color, practices that are widely accepted within the gem trade when properly disclosed.
Any treatments or enhancements are always clearly stated for each individual gemstone. Every stone is professionally examined, and transparent disclosure is regarded as a fundamental part of responsible gemological practice, allowing clients to make informed and confident decisions.
