This radiant ring features a GIA certified Fancy Vivid Yellow diamond of Zimmi origin. Zimmi diamonds come from a specific alluvial deposit in southern Sierra Leone. Unlike most diamonds sourced from kimberlite pipes deep within the earth, Zimmi diamonds are recovered from riverbed and sediment deposits. They are rare Type Ib diamonds, in which a single nitrogen atom replaces a single carbon atom; that nitrogen atom absorbs violet and blue light, resulting in a rich canary yellow color. The ring is beautifully crafted in 18kt white and 22kt yellow gold, and is part of a suite with matching earrings.
