Pink faceted gemstone, likely synthetic cubic zirconia or pink sapphire

Uncertain from image; possible zirconium dioxide (cubic zirconia, ZrO₂) or corundum (pink sapphire, Al₂O₃)

AI-generated identification · may be incorrect

Oval brilliant/faceted cut with pink-lavender color, vitreous-to-adamantine luster, and strong brilliance; hardness is approximately Mohs 8–8.5 for cubic zirconia or 9 for sapphire. Mounted in a ring, so cleavage and specific gravity cannot be determined visually.

Physical properties

Formation & geological history

If cubic zirconia, it is laboratory-grown rather than geologically formed; pink sapphire forms naturally in metamorphic or igneous environments through trace-element coloration. Geological age depends on its source and cannot be established from the photograph.

Uses & applications

Used primarily in jewelry as a diamond simulant or colored gemstone; the surrounding metal appears to be a ring setting.

Geological facts

The large, very bright oval and abundant rainbow-like dispersion are especially consistent with cubic zirconia, though identification requires testing. Pink sapphire generally has less dispersion and higher durability.

Field identification & locations

Check with a loupe for inclusions, use a refractometer or thermal/electrical tester, and avoid relying on color alone; a gemologist can distinguish the alternatives. Similar stones occur worldwide, while synthetic cubic zirconia is manufactured globally.
