Small pale mineral fragment, likely quartz or calcite

Tentatively quartz (SiO₂) or calcite (CaCO₃); image resolution prevents confident identification

AI-generated identification · may be incorrect

Tiny cream-white, translucent to opaque, irregular crystalline piece with vitreous to pearly luster; quartz hardness 7 with no cleavage, calcite hardness 3 with prominent rhombohedral cleavage. Crystal structure and specific gravity cannot be determined reliably from the photograph.

AI Estimated Value

$0–$5 for a common tiny fragment; possibly $10–$30 if it proves to be an attractive, well-formed crystal.

Physical properties

Formation & geological history

Could form in hydrothermal veins, cavities, or sedimentary/limestone environments; geological age is indeterminate from the image.

Uses & applications

Quartz is used in glass, electronics, abrasives, and jewelry; calcite is used in cement, aggregate, lime, and as a collectible mineral.

Geological facts

A steel nail or knife can scratch calcite but not quartz; dilute vinegar may fizz on calcite, though testing a tiny specimen is inadvisable if it has collector value.

Field identification & locations

Look for quartz’s glassy fracture and hexagonal points versus calcite’s blocky/rhombohedral cleavage and vinegar reaction. Common worldwide, especially in quartz veins and carbonate rocks.
