Physical properties
Yellow, purple, and green round faceted stones with vitreous luster. Hardness and crystal structure cannot be determined visually; synthetic corundum is Mohs 9, while glass is about 5–6.
Formation & geological history
These appear cut and possibly lab-made or imitation; the image cannot establish their material or age. Natural corundum forms in metamorphic rocks and some igneous deposits.
Uses & applications
Used in jewelry, costume jewelry, or collecting; synthetic corundum is also used in technical applications.
Geological facts
Bright, uniform colors and similar cuts can occur in lab-grown stones, but appearance alone cannot distinguish them from natural gems or glass.
Field identification & locations
A gemological hardness, refractive-index, or laboratory test is needed for identification. Similar stones are produced worldwide; value depends strongly on confirmed material, size, and quality.
