Item Description South Sea Pearl & Diamond Ring | Pt900 Platinum | 12.07 × 11.83 mm Natural Pearl | JGL Certified | Japan A luminous and refined platinum ring centred on a certified natural South Sea pearl — one of the ocean's most coveted gems — accompanied by a Japan Gem Laboratory identification report confirming its authenticity and natural origin. The South Sea pearl measures 12.07 × 11.83 mm, placing it firmly in the large-pearl category that collectors and connoisseurs prize. Its body colour is a distinguished light silvery grey — a naturally occurring and highly sought-after tone produced by the silver-lipped oyster (Pinctada maxima) in the warm waters of Australia, Indonesia, and the Philippines. The pearl displays characteristic fluorescence under both long-wave and short-wave UV light, and surface magnification confirms the authentic pearl structure, as documented in the accompanying JGL report (Certificate No. A90387). Specific gravity measurement could not be performed due to the ring setting, as noted in the certificate. Framing the pearl on either side is a graceful spray of natural diamonds set in a floral marquise-and-round-brilliant cluster arrangement — a design that captures light from every angle and gives the piece the presence of a fine jewellery house creation. The setting and shank are crafted in platinum hallmarked Pt900 (90% platinum) on the inner shank, the standard of choice for high-end Japanese jewellery. A reference stamp "069" also appears on the inner shank. Total weight of the ring is 9.94 g. This ring is accompanied by an original Japan Gem Laboratory (日本宝石研究センター, JGL) Gem Identification Report, No. A90387, identifying the centre stone as a natural South Sea pearl.
