Boghossian - 18-Karat White Gold Multi-Stone Ring - 4 3/4

Boghossian's 'Art of Inlay' is inspired by the ancient technique of carving stones, so they sit seamlessly together. Framed by tiny brilliant-cut diamonds, this 18-karat white gold ring is filled with pear-cut rock crystal and an aquamarine - notice how they're faceted for ultimate sparkle.
