Tumbled pale-blue quartz, possibly aquamarine

Quartz (SiO₂), with a possible beryl (aquamarine) alternative

AI-generated identification · may be incorrect

Small translucent, pale blue-green, glassy specimen with rounded/tumbled surfaces. Quartz hardness is Mohs 7, no cleavage, conchoidal fracture, vitreous luster, and specific gravity about 2.65; aquamarine is beryl (Be₃Al₂Si₆O₁₈), hardness 7.5–8, typically hexagonal.

Common name: Tumbled pale-blue quartz, possibly aquamarine
Scientific name: Quartz (SiO₂), with a possible beryl (aquamarine) alternative
Category: mineral
Identified: September 18, 2026
Method: Standard

AI Estimated Value

About $1–$10 as a common tumbled quartz fragment; roughly $5–$30 if confirmed as attractive low-grade aquamarine. Gem-quality value requires clarity, saturation, and cutting potential.

Physical properties

Formation & geological history

Likely a naturally rounded or human-tumbled fragment from a hydrothermal vein or pegmatite. Exact age cannot be determined visually; both quartz and beryl commonly form in granitic pegmatites.

Uses & applications

Quartz is used in glass, electronics, abrasives, and collections; gem-quality blue quartz is uncommon. Aquamarine is a jewelry gemstone, but this piece appears too small and included for significant gem value.

Geological facts

The image alone cannot reliably distinguish pale blue quartz from aquamarine; visible crystal faces, hardness, refractive index, and specific gravity tests would help.

Field identification & locations

At about 34.5°N, 69.3°E, pegmatite-related quartz and beryl are geologically plausible in the broader Hindu Kush region. Test with a steel file: quartz should resist scratching; a jeweler’s loupe may reveal hexagonal beryl form.
