GR29 - Mediterranean Marquise Shape RingDESCRIPTION Gerochristo Collection. This ring fully utilizes the brand's openwork technique on a large oval motif. Not only the top motif, but also the sides of the ring are hollow and openworked, creating a ring that is seemingly large, but also shows delicate craftsmanship. The design, which could never be created by wax casting alone, is unique to GEROCHRISTO.
