Natural Citrine 12.05 ct – Cushion, Heated, ČGL Certified

Citrine is a yellow to golden-orange variety of quartz, appreciated for its warm color tones and natural clarity. Within the quartz family, it is valued for its brightness and versatility, with colors ranging from pale lemon to deeper honey shades, depending on natural conditions and treatment.
Chemically composed of silicon dioxide (SiO₂), citrine belongs to the silicate mineral group and crystallizes in the trigonal crystal system, like other quartz varieties. In gem-quality material, it typically displays a vitreous luster with transparent clarity.
The refractive index of citrine generally ranges from 1.544 to 1.553, producing a soft, even brilliance rather than pronounced dispersion. Natural citrine is found in several regions worldwide, with typical sources including Brazil, Madagascar, Spain, and parts of Africa.

With a hardness of 7 on the Mohs scale, citrine offers good durability suitable for everyday jewelry when properly set and worn with standard care. It performs reliably in a wide range of designs, including rings, pendants, earrings, and bracelets.
As with other quartz varieties, citrine benefits from protective settings in rings, particularly for larger stones. Its combination of durability, availability in generous sizes, and warm, approachable color makes citrine a practical and visually appealing choice for both everyday jewelry and expressive, statement-oriented designs.

Natural citrine is relatively rare. A significant portion of citrine available on the market is produced by heat-treating amethyst or smoky quartz, a practice that is widely accepted within the gem trade when clearly 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.
