An octagon pendant - eight sides, architectural precision - with an emerald-cut green CZ at its center surrounded by a white CZ halo, the geometric outer frame giving the pendant a strong, intentional silhouette that reads clearly from across a room. The octagon form references Art Deco geometry while the color CZ center and CZ halo frame bring it into current fashion territory. In 14K gold over sterling silver on a 16-inch chain with lobster claw clasp and extender. The emerald cut in the center is the right choice for this application: its stepped facets display the green color broadly, making the color legible within the complex geometry of the octagon surround.
