Physical properties

Emerald has Mohs hardness 7.5–8, vitreous luster, and a hexagonal crystal structure; its green color comes mainly from chromium and/or vanadium. The image does not establish whether the stones are natural, treated, or synthetic.

Formation & geological history

Natural emeralds crystallize in beryllium-rich rocks and hydrothermal veins; deposits range from ancient to geologically recent. The pendant’s stones cannot be dated or assigned a source from the image.

Uses & applications

Geological facts

Emerald is a variety of beryl, not a separate mineral species; inclusions are common and often called a jardin.

Field identification & locations

The green faceted stones in the gold-colored setting suggest emerald, but appearance alone cannot confirm identity or natural origin; gemological testing is needed. Emeralds occur notably in Colombia, Zambia, Brazil, and Afghanistan.
