Twenty-three carat precious stones represent the absolute pinnacle of natural perfection – existing at such extraordinary rarity that many varieties have produced fewer than 2 documented specimens of this size in gem quality throughout human history. Their remarkable presence elevates them beyond conventional collectibles to important scientific specimens worthy of perpetual preservation. Natural, untreated gems of this magnitude represent serious investments that have consistently demonstrated exceptional appreciation, with fine examples establishing price records that remain unbroken for generations at prestigious international auctions.
