Russian 5 Ct Demantoid Fancy Colored Diamond Antique Ring

Buyer Protection Guaranteed

About

The ring is set with an exceedingly rare Ural demantoid garnet weighting 5.1 ct, encircled by a single row of six white and six fancy colored old cut diamonds with an approximate total weight 1.80 carats.

The ring comes with GIA and AGL reports. AGL - the demantoid is of Ural Mountains origin (Russia), has an excellent color stability, no clarity enhancement.

The dark grass green stone is full of valuable so-called "horsetails", inclusions found only in demantoids from the Urals.

First discovered in the Russia's Ural mountains in 1868, demantoid became immediately popular and was highly valued by Russian aristocracy.

Modern supply of the Uralian demantoids is very limited, making the stone one of the rarest and most valuable gems on earth.

Demantoids are usually found in sizes of less than a carat, larger stones are extremely rare.

The diamonds are set in silver over rose gold. The shank is a later replacement. Struck with Russian control marks for antique silver and gold.
