Vintage 47-Carat Aquamarine, Pearl Diamond Platinum Choker Necklace

A Vivid Natural Aquamarine Framed by Diamonds and Luminous Cultured Pearls An exceptional jewel of dramatic scale, this vintage platinum choker necklace centers upon a magnificent natural aquamarine weighing approximately 47.00 carats. Its vivid blue saturation and medium tone give the gemstone remarkable depth and presence, while its substantial rectangular form creates an unforgettable focal point. Measuring approximately 28.0 × 21.22 × 11.70 mm, the faceted aquamarine is secured within an elaborate geometric platinum mounting accented by natural diamonds. Milgrain details, circular diamond motifs and angular architectural elements bring a distinct Art Deco influence to the centerpiece without making a definitive claim about the necklace’s period. Multiple strands of luminous round cultured pearls, measuring approximately 4.21 mm, form the necklace’s wide, graceful silhouette. Their soft iridescence provides an elegant contrast to the intense blue aquamarine. Diamond-set platinum spacer bars organize the pearl strands and give the composition structure, balance and brilliance. Throughout the necklace, 83 natural diamonds totaling approximately 4.20 carats embellish the aquamarine surround, spacer bars and clasp. According to the AGI New York appraisal, the diamonds are graded G–H color and VS–SI clarity, with good polish and symmetry. Crafted in platinum, the necklace combines the softness and refinement of pearls with the exceptional color of a large aquamarine and the crisp brilliance of diamonds. The result is a sophisticated statement jewel with the presence of a couture creation. The necklace is documented by AGI New York Gemstone Appraisal Report No. DC26038201201.
