A diamond necklace featuring a unique Japanese "twist plum" clasp. The diamond sparkles beautifully in the center of the elegant and beautiful plum motif. The slender prongs support the diamond, exuding delicate refinement and a charming beauty that resonates even today. Although not noticeable during wear, some gold color is visible due to the gold solder. The chain is modern, and the top is presumed to be either a modification of the hallmark or a remake. Considering the use of gold solder on platinum, we believe the top is not a contemporary piece, and the carat marking may not be accurate.
