Jeweler Monique Pean made her name with sliced wooly mammoth, sustainable gemstones and recycled materials. But you wouldn't know it by just looking. Pean's engagement rings might be a far cry from fossilized ivory culled from the ice-caps, but they're just as unique and just as striking. Exquisitely set and unusually cut diamonds in crystal clear, pale yellow and dense black surrounded by her signature strand of tiny diamonds manage to marry her thoroughly modern esthetic with a raw, unfettered abandon. Pean's herkimer diamond caught in a cage of diamonds is like the elegant taming the wild. Beauty and the beast. His yin to your yang. A perfect marriage.
