Red faceted gemstone jewelry setting

Likely synthetic ruby or red spinel centerpiece with colorless accent stones; exact identification requires gemological testing

AI-generated identification · may be incorrect

The central stone is transparent, deep red, faceted, and strongly lustrous, surrounded by small colorless faceted stones in a metal setting. Ruby is corundum (Mohs 9, trigonal); spinel is MgAl₂O₄ (Mohs 7.5–8, cubic); appearance alone cannot distinguish them.

Physical properties

Formation & geological history

Natural ruby and spinel form in metamorphic rocks, generally over millions to billions of years; jewelry examples commonly use laboratory-grown or synthetic stones. The surrounding stones may be diamonds, zircon, cubic zirconia, or glass.

Uses & applications

Used primarily in jewelry and adornment; ruby has high jewelry value, while synthetic ruby, spinel, and cubic zirconia are economical alternatives.

Geological facts

A ruby’s red color is mainly caused by chromium, whereas red spinel is colored by chromium or iron. Faceting and mounting obscure diagnostic features such as inclusions, cleavage, and crystal habit.

Field identification & locations

Identify with a loupe, refractometer, polariscope, spectroscopy, and thermal/electrical testing; hardness tests should not be performed on mounted gems. Common sources include Myanmar, Mozambique, Sri Lanka, Vietnam, and Tanzania, but origin cannot be determined visually.
