Gold Opal and Seed Pearl Pendant

Opal (hydrated amorphous silica, SiO₂·nH₂O) with natural pearls (mostly aragonite, CaCO₃) in a gold setting

AI-generated identification · may be incorrect

The central cabochon appears to be pale precious opal with possible play-of-color, surrounded by seed pearls and gold-colored metal. Opal hardness is about 5.5–6.5 Mohs, vitreous to waxy luster, and amorphous structure; pearls are about 2.5–4.5 Mohs with nacreous luster.

Physical properties

Formation & geological history

Opal forms when silica-rich groundwater fills cavities and fractures, commonly in volcanic or sedimentary settings, generally during the Cenozoic. Pearls form as nacre around irritants in mollusks; the pendant itself is a human-crafted jewelry specimen.

Uses & applications

Used primarily as jewelry and collectible art; opal and pearls have ornamental value, while gold contributes durability and resale value.

Geological facts

Opal can lose water and craze under severe drying or heat. Natural seed pearls are typically irregular and much smaller than cultured pearls.

Field identification & locations

Identify opal by its low hardness, curved fracture, and—if precious—flashing spectral play-of-color; pearls show layered nacre and a gritty feel when gently rubbed against teeth (do not damage valuable jewelry). Common sources include Australia, Ethiopia, Mexico, and historic pearl fisheries worldwide.
