Physical properties

Polished, rounded beads in blue, gray, and brown tones. Quartz has Mohs hardness 7, vitreous luster, and a trigonal crystal structure; the other beads’ properties are uncertain.

Formation & geological history

Quartz forms in many geological settings, commonly crystallizing from silica-rich fluids in fractures and cavities. The bracelet may combine stones from different sources and ages.

Uses & applications

Primarily worn as jewelry; gemstone beads are also used in craftwork and collecting.

Geological facts

The handwritten note appears to mention blue quartz, but the photograph does not establish that every bead is quartz or verify any specific stone varieties.

Field identification & locations

The polished beads indicate worked geological materials, but color and appearance alone are insufficient for field identification; inspect translucency, hardness, and internal features, or have a gemologist test them.
