A distinguished antique stickpin in 18ct yellow gold, dating to circa 1880, set with a fine natural saltwater pearl of 6.9 × 7.7 × 10.7mm — accompanied by a laboratory certificate confirming the pearl as natural saltwater origin. Natural saltwater pearls are among the rarest and most valuable of all pearl types, formed without human intervention over many years, and a certified example of this size is a genuinely significant find. The pearl's warm, organic lustre sits with quiet authority atop the 18ct gold pin.

A stickpin of real rarity and provenance — the laboratory certificate transforms this from a beautiful antique accessory into a piece of documented natural history, and a certified natural saltwater pearl of this dimension in an 18ct gold antique mount is a combination that is increasingly difficult to source.
