Pippa Small - 18-Karat Gold, Kyanite And Tanzanite Ring - 6

Pippa Small's ring is inspired by work of James Turrell, a leader of California's 'Light and Space' movement in the '60s. Cast from 18-karat gold, it's set with uneven, hand-cut Brazilian kyanite and Tanzanian tanzanite that nod to the sensual, light-filled blues used by the artist.
