Polished yellow gemstone fragments, likely citrine or yellow sapphire

Uncertain from image; likely quartz (SiO₂) if citrine, or corundum (Al₂O₃) if yellow sapphire

AI-generated identification · may be incorrect

Tiny transparent yellow faceted pieces with vitreous luster; citrine has Mohs hardness 7 and no cleavage, while yellow sapphire has hardness 9 and strong durability. Color and appearance alone cannot distinguish them reliably.

Physical properties

Formation & geological history

Citrine forms in silica-rich hydrothermal veins and pegmatites, commonly through heat-treated amethyst; sapphire crystallizes in aluminum-rich igneous or metamorphic rocks. Their ages vary widely by deposit.

Uses & applications

Used as jewelry stones and mineral specimens; sapphire generally has substantially greater gem value and durability.

Geological facts

The image is insufficient for confident identification because scale, optical behavior, inclusions, and testing are unavailable. Yellow stones may also be topaz, zircon, heliodor, or glass.

Field identification & locations

Check refractive index, specific gravity, hardness, and inclusions with gemological instruments; citrine is commonly found in Brazil, Madagascar, and Uruguay, while yellow sapphire occurs in Sri Lanka, Madagascar, and Tanzania.
