EMERALD

EMERALD

Reference stone from the laboratory archive. This page is for species recognition; it is not a numbered GRA report.

Gem experts differ on the degree of green that makes one stone an emerald rather than a green beryl. Clarity enhancement is common in the trade and must be disclosed on laboratory documents.

GRA reports record identity and treatments so emerald can be described the same way from cutter to retailer. Color, clarity characteristics and fillings are not guessed from a photograph alone.

This Featured page is educational. A numbered certificate is verified separately under Certificate.
