Art Deco 47-Carat Aquamarine, Pearl Diamond Platinum Choker Necklace
An Art Deco Aquamarine Framed by Diamonds and Luminous Cultured Pearls
An exceptional Art Deco jewel of dramatic scale, this 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. Fine milgrain detailing, circular diamond motifs and angular architectural elements reflect the refined geometry and precise craftsmanship associated with Art Deco jewelry.
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, this impressive Art Deco 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 and craftsmanship of a couture creation.
The necklace is documented by AGI New York Gemstone Appraisal Report No. DC26038201201.

Collector’s Note
A natural aquamarine of approximately 47 carats gives this necklace exceptional visual importance, but it is the complete composition that makes the jewel especially compelling. The contrast between the aquamarine’s vivid blue color, the delicate luster of the cultured pearls and the architectural brilliance of the diamond-set platinum creates a sophisticated balance of softness and strength.
Large aquamarines are often presented as solitary pendants or cocktail jewels. Here, the gemstone becomes the centerpiece of an elaborate multi-strand pearl necklace, transformed through the geometry and refined craftsmanship of the Art Deco period into a fully realized statement jewel. Its impressive scale, fine materials and distinctive construction make this an extraordinary acquisition for a collector seeking an important Art Deco jewel with both elegance and commanding presence.
All gemstone weights and measurements are approximate and taken from the AGI New York appraisal report. Grading was performed as the mounting permitted. As stated in the report, gemstones are presumed to have been subjected to stable, commonly used and possibly undetectable enhancements.

How do I know a piece is authentic, and can I trust DSF?
Buying fine jewelry online takes trust, especially at this level. DSF Antique Jewelry is a New York–based dealer with over 50 years of fine jewelry expertise. Every piece is examined for authenticity and condition before it is listed — we assess hallmarks, maker's marks, metal content, gemstones, and construction consistent with the stated period or designer. For signed pieces such as Cartier, Buccellati, or Van Cleef & Arpels, we verify maker's marks and signatures. We're glad to send additional photographs of any hallmark, or speak with you directly, before you decide.
Why does antique gold look different, and is surface wear normal?
Antique pieces were often made in gold standards less common today, such as 15ct (used in Britain only between 1854 and 1932), 9ct, or higher-karat continental gold, which give a warmer tone than typical modern 14k. Light surface wear, softened edges, and a gentle patina are normal and expected on antique jewelry — they reflect the age and authenticity of the piece, not flaws. We describe the true condition of every item honestly in its listing.
What do the hallmarks and maker's marks mean?
Hallmarks are small stamped marks that identify the metal standard, and often the maker, assay office, and date. They are one of the best tools for authenticating antique jewelry. We identify and explain the marks we find on each piece in its description, and we're happy to send close-up photographs of any hallmark on request so you can see exactly what you're buying.
Can pieces be resized or adjusted?
It depends on the piece. Many antique rings can be resized, but bands with all-around engraving, thin shanks, or gemstones near the base may be limited in how far they can safely go, and some pieces are best left as-is to preserve their integrity. We list each item's measurements as they currently are. If you're unsure whether something can be safely adjusted, contact us before buying and we'll give you an honest assessment for that specific piece.
How should I care for and store fine jewelry?
Clean gently with a soft cloth, avoid harsh chemicals, ultrasonic cleaners, and chlorine, and store pieces separately so they don't scratch one another. Remove rings and bracelets for heavy manual tasks. Antique gold is softer than modern alloys, so period pieces are best enjoyed with normal care. Treated well, fine antique jewelry lasts for generations — many of our pieces are already a century or more old and still beautiful.
