A 19th century antique cabochon chrysoprase and rose cut diamond gold ring.

Chrysoprase is the most valuable variety of chalcedony gem stones. Because of its semi-opaque green color, chrysoprase is often mistaken for Imperial jadeite.

In Russia, the stone is mined in the Ural mountains.

This beautiful green cabochon chrysoprase is set in a fancy bezel encrusted with 82 rose cut diamonds.

The chrysoprase has some chips on the back which are not visible from the front.

US ring size 7 (17 mm)

The cabochon chrysoprase has an approximate weight of 3.25 ct.
