Physical properties

Formation & geological history

These are natural silica-rich lapidary materials formed by groundwater deposition, volcanic cavities, or silica replacement in rock; ages vary widely, commonly from Paleozoic to Cenozoic deposits. Their exact identities cannot be confirmed from the photograph alone.

Uses & applications

Used for jewelry, ornaments, and collecting; value depends on confirmed material, color, pattern, polish, and workmanship.

Geological facts

The bracelet appears mixed rather than a single uniform mineral, with several beads resembling ocean jasper or orbicular jasper and others resembling agate or moss agate.

Field identification & locations

Identify by translucency, waxy/vitreous luster, hardness, and natural patterning; a streak, loupe examination, and gemological testing can distinguish dyed or composite beads. Similar materials occur in Madagascar, Brazil, Uruguay, India, and Mexico.
