Black diamonds, marble and jadeite are far from expected when it comes to wedding day jewels. The brother and sister design team behind the jewelry label Completed Works gravitate towards the unexpected. Their signature collection, Pillar, is inspired by architectural ruins, specifically the shapes of the classic columns. "Using specially selected marble and jadeite to complement the precious metal designs, the collection captures the fragility of constructions," says the label's artistic director and designer Anna Jewsbury. Muted and clean, Completed Works' sculptural designs are also extremely wearable works of art.
