17.42ct Emerald-Cut Zambian Emerald Three-Stone Ring with Trillion Diamonds, Platinum

A 17.42-Carat Zambian Emerald in Platinum

At the center of this ring is a 17.42-carat Zambian emerald in an emerald cut, the shape that was developed for this gemstone. Its long, stepped facets draw the eye into the depth of the green rather than scattering light, and its cut corners help protect the stone.

Two GIA-certified trillion-cut diamonds, 2.22 carats in total weight, flank the emerald, their triangular outlines widening the ring's profile across the finger, and pavé-set round diamonds continue along the band. Pointed double claw prongs hold each corner of the emerald, and the ring is made in platinum, whose naturally white color sets off both the green of the emerald and the brightness of the diamonds.

Zambia is one of the world's most important sources of fine emerald, and a center stone of this size makes this a one-of-a-kind piece. The ring is currently a size 6.25; ask us about sizing.

Emerald Treatment and Care

Like most emeralds, this stone has been clarity enhanced with oil, a long-standing practice in the emerald trade that makes tiny surface-reaching fissures less visible. Because the treatment is not permanent, keep the ring away from ultrasonic and steam cleaners, heat and harsh chemicals. Clean it with lukewarm water, mild soap and a soft brush, and have the prongs checked periodically.
