Cyan Yb:YAG 7.21 cts. 20.1 × 11.5 mm, Tribal Frosted

Yb:YAG — Ytterbium-doped Yttrium Aluminum Garnet — is a synthetic laser crystal that rarely finds its way into a gem setting, and this trillion is a testament to why it should. Cut in Marco Voltolini's Tribal design with frosted facets added at the pavilion junctions — a creative departure from the original — they radiate from the center in a starburst pattern, creating an optical illusion of sweeping curved lines through the stone's clear light cyan interior. Flashes of spectral color at the edges complete a gem that is equal parts science and art.
