This ring most likely dates from the Edwardian period. It is crafted in Platinum over Gold. It is set with (20) mine cut Diamonds. All the Diamonds are sparkly and eye-clean. An estimate grade would give them I-J color, and VS-SI clarity. An interesting feature of this ring is that the pearls appear to consist of almost totally nacre, instead of having just a thin layer. It is possible that they are natural pearls, rather than cultured. The Ring is a size 4, and can be sized.
