Polished honey-colored chalcedony cabochon ring

Microcrystalline quartz (SiO₂), likely yellow/orange chalcedony or agate

AI-generated identification · may be incorrect

Mohs hardness 6.5–7; translucent honey-yellow body, waxy to vitreous luster, cryptocrystalline quartz with no visible cleavage, and specific gravity about 2.60–2.65. The stone is a polished cabochon set in metal; exact identity cannot be confirmed from the image alone.

Physical properties

Mohs hardness 6.5–7; translucent honey-yellow body, waxy to vitreous luster, cryptocrystalline quartz with no visible cleavage, and specific gravity about 2.60–2.65. The stone is a polished cabochon set in metal; exact identity cannot be confirmed from the image alone.

Formation & geological history

Chalcedony forms when silica-rich fluids fill cavities and fractures, commonly in volcanic rocks; coloration may result from iron compounds or dyeing. Deposits range from Cenozoic to much older volcanic-hosted formations.

Uses & applications

Used for rings, cabochons, beads, carvings, and ornamental objects; durable enough for everyday jewelry. Commercial value is usually modest unless color, translucency, pattern, or provenance is exceptional.

Geological facts

Honey chalcedony is often marketed as yellow agate, citrine-like chalcedony, or bumblebee-style material, though names can be inconsistent. A refractive-index or specific-gravity test can separate it from glass and many imitations.

Field identification & locations

Identify by its waxy appearance, fine texture, lack of cleavage, and resistance to scratching by steel; glass may show bubbles or conchoidal fractures. Common sources include Brazil, Uruguay, India, Madagascar, and Mexico.
