Diamond Prism Necklace

From $290

A bright white hexagonal rose cut diamond reminds us of a prism in the way it reflects and refracts light, separating white light into a spectrum of colors. In this unique design, the stone is prong set on a delicate 14k gold chain for a look that is both classic in its simplicity and modern in its approach. The Diamond Prism Necklace is an everyday piece that is anything but ordinary.

A prong-set rose cut hexagonal diamond (3.5mm, SI clarity, bright white color)

Solid 14k gold setting on a delicate 18” rope chain with a 2" station for length adjustment (available in yellow, rose, or white gold)

Limited Edition
