Art Deco Platinum 0.50 Carat Emerald-Cut Diamond and Emerald Stick Pin
This refined Art Deco stick pin is crafted in platinum and centered by an approximately 0.50-carat emerald-cut diamond of D–E color and VS clarity. The diamond’s crisp rectangular outline and elegant step-cut facets give the jewel a bright, sophisticated presence.
Vivid green calibré-cut emeralds are precisely fitted around the center stone, forming a bold geometric frame characteristic of Art Deco jewelry. Additional diamond accents at the corners add brilliance while emphasizing the architectural symmetry of the composition.
The combination of a high-quality colorless diamond, richly colored emeralds, and platinum creates a striking contrast. Elegant yet distinctive, this antique jewel reflects the precision, symmetry, and sophisticated use of color associated with the Art Deco period.
Originally designed to be worn on a tie, cravat, scarf, or lapel, the pin may be styled traditionally or incorporated into a modern wardrobe as a unique collector’s accessory.

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.
