Faceted purple-blue beads, likely synthetic glass or treated gemstone

Indeterminate; possible synthetic corundum, synthetic spinel, or dyed quartz (SiO₂)

AI-generated identification · may be incorrect

Faceted, strongly transparent beads with vivid blue-purple color and vitreous luster; apparent hardness cannot be determined from the image. Small gold-colored spacer beads are non-geological jewelry components.

AI Estimated Value

Approximately $5–$40 for a common costume strand; $50–$300+ if confirmed as quality natural sapphire, amethyst, or another valuable gemstone with precious-metal findings.

Physical properties

Formation & geological history

The material appears manufactured or color-treated rather than naturally formed; if quartz, it is crystalline SiO₂, while synthetic corundum is Al₂O₃. Geological age is not applicable to the finished beads.

Uses & applications

Used in costume or fashion jewelry; value depends on confirmed material, treatments, uniformity, and metal content. The gold-colored spacers may be plated base metal rather than solid gold.

Geological facts

Strongly uniform color, repeated faceting, and bead drilling suggest commercial production. A gemological refractometer, polariscope, microscope, and specific-gravity testing are needed for identification.

Field identification & locations

Inspect inclusions, facet wear, bubbles, and color concentration around drill holes; glass commonly shows round gas bubbles, while natural stones often show irregular inclusions. The image alone cannot distinguish glass from synthetic or treated gemstones.
