Physical properties
The earring appears to contain transparent, colorless faceted stones, likely quartz; visual identification is uncertain. Quartz has Mohs hardness 7, a vitreous luster, and a trigonal crystal structure; the metal setting is not geological material.
Formation & geological history
Quartz crystallizes from silica-rich fluids and magma in many geological environments, over a wide range of geological ages.
Uses & applications
Quartz is used in jewelry and, industrially, in glassmaking and electronics. This small set stone has modest value unless testing or provenance identifies a rarer gem.
Geological facts
The photograph does not show diagnostic features sufficient to distinguish quartz from glass or other clear gemstones.
Field identification & locations
Look for hardness, crystal inclusions, and natural growth features; identification may require gemological testing. Common sources include Brazil, Madagascar, and the United States.
