This 14K rose gold Pascale Monvoisin Orso No. 1 moonstone diamond pendant necklace has been crafted in France. Featuring an adjustable 14K rose gold link chain, this piece has a round cut diamond set within a moonstone on a 9K rose gold pendant and a lobster clasp fastening. Wilkie Collins wrote a novel called The Moonstone, which is a work of exemplary detective fiction. And this Pascale Monvoisin moonstone necklace is worthy of similar praise - as a piece of exemplary jewellery.
