Physical properties

Hardness: 6.5 to 7 on Mohs scale. Color: Bright orange-yellow to golden. Luster: Vitreous to waxy. Transparency: Translucent to semi-opaque. Cleavage: None. Specific gravity: ~2.6.

Formation & geological history

Formed through low-temperature hydrothermal deposition of silica within cavities of volcanic and sedimentary rocks.

Uses & applications

Used primarily in jewelry making for bead bracelets, necklaces, carved figurines, and decorative lapidary arts.

Geological facts

Yellow chalcedony, often marketed as yellow jade or orange aventurine, is a microcrystalline form of quartz. Highly polished round beads like these are very popular in holistic healing and crystal jewelry.

Field identification & locations

Identified by its warm orange-yellow translucent appearance, smooth polished finish, and hardness that easily resists scratching by a steel blade. Commonly mined in Brazil, India, Madagascar, and Uruguay.
