Antique Colombian Emerald and Diamond Cluster Ring 

The Cosette ring is an authentic vintage emerald and diamond ring from the Victorian Era circa 1890. The ring centers a GIA-certified Octagonal Step Cut Colombian Emerald of moderate clarity enhancement weighing approximately 1.20-carats. Surrounding the center stone is a halo of 12 Old Mine Cut diamonds of approximately I-J color, VS-I clarity combining for roughly 0.60-carats. The stones are set in an 18kt yellow gold engraved setting. The ring is currently size 7.75 and can be resized!

Why We Love It

Intricate, chunky gold plays beautifully with a perfectly hued emerald center stone and a shimmery halo of old mine-cut diamonds in this golden antique piece. She lays flat to the finger for a low-profile fit.

The dimensions of the center stone are 6.55 x 6.23 x 4.27.
