Purple has always been the color of something rare. This one-of-a-kind cushion-cut purple sapphire — deep, velvety, and wholly its own — is bezel-set in 18k yellow gold, with tiny diamonds dotting the band like punctuation marks on a love letter. An engagement ring for the romantic who sees the world in color.
