Antique Diamond Trefoil Clover Stick Pin
An Elegant Edwardian Trefoil Set with Approximately 1.00 Carat of Exceptional E–F Color Diamonds
This refined antique stick pin, dating to the Edwardian period, is designed as a stylized trefoil or three-leaf clover. Three prominent old-cut diamonds form its beautifully rounded leaves around a smaller central diamond, while an additional diamond-set curved element creates the graceful stem below.
Crafted in platinum and gold, the stick pin contains approximately 1.00 carat of notably high-quality diamonds displaying an exceptional E–F color. The cool platinum setting emphasizes their crisp, colorless brilliance, while the gold pin provides the elegant contrast characteristic of fine Edwardian jewelry.
Delicate yet visually striking, this jewel may be worn on a lapel, tie, cravat, or scarf. Its balanced trefoil design gives it both decorative beauty and enduring symbolic appeal.

Collector’s Note
Edwardian stick pins were often conceived as subtle accessories, making this example particularly impressive for its approximately one-carat diamond weight and exceptional E–F color. The bold trefoil arrangement, delicate diamond-set stem, and period platinum-and-gold construction create a refined jewel with substantial presence despite its compact scale.

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.
