A beautiful graduated natural pearl with a diamond set platinum clasp set necklace from the first period of the 20th century. Exceptionally rare and precious, these Natural Pearls, would have been discovered by divers searching wild Oysters for this prized gem. A natural pearl occurs by chance with no interference by man, which is what differentiates them from a Cultured Pearl. Natural pearls are rarely seen for sale, as it is now illegal to harvest wild oysters, so necklaces such as this are truly special as only antique pieces are available. This heirloom necklace features pearls of graduating size from the tiny 1mm spacer pearls that sit between the larger 1.6-4.5mm pearls. Each pearl enjoys an individual shape with a lovely ivory white colour, beautiful lustre and shimmering orient. The necklace measures 16 inches and the pearls have been verified by a leading Pearl expert as 100% Natural Saltwater Pearls, rather than cultured or fresh-water pearls. The 9k Gold push-in marquise shape antique clasp has a sapphire and rose-cut diamonds..This necklace is part of our pre-owned collection, which we restore back to good condition by gently cleansing the pearls and polishing the clasp to its original shine. We use a reputable restringing service to restring the pearls on natural silk, so you can enjoy many years of wear.
