Diamond 18K Yellow Gold Hinged Bypass Ring, 6 Carats
Vintage Gold Crossover Ring with Fine F Color Diamonds
This striking vintage diamond bypass ring combines substantial 18K yellow gold with an elegant crossover design. Its sweeping, interlocking sections are richly set with round brilliant-cut diamonds, creating exceptional brilliance and impressive coverage across the finger.
According to the appraisal, the diamonds total approximately 6.00 carats. They display an impressive F color, standing out beautifully against the warmth of the polished yellow gold. Smooth gold borders frame the diamond-set surfaces and emphasize the ring’s dimensional, fluid silhouette.
A thoughtfully engineered hinged construction allows the ring to open for easier and more comfortable placement over the finger. The ring measures approximately size 6.5 when closed, but because of its hinged structure, it can accommodate approximately a size 7. Weighing approximately 16.4 grams, the ring has a substantial yet well-balanced presence on the hand.
Combining fine diamonds, distinctive vintage design and an unusual hinged mechanism, this sophisticated ring is equally suited for evening wear, special occasions or as an impressive addition to a fine jewelry collection.

Construction Note
This ring is distinguished by a precisely engineered spring-hinged shank. The hinge and internal spring component allow the ring to open slightly as it passes over the finger, providing easier placement and accommodating the difference between the knuckle and the base of the finger. When closed, the mechanism integrates discreetly into the substantial 18K gold mounting, preserving the ring’s smooth and continuous silhouette.
Open honeycomb-style galleries beneath the diamonds further demonstrate the care invested in its construction. This thoughtfully designed framework supports the extensive diamond setting while allowing access to the reverse of the stones. The combination of mechanical functionality, substantial goldwork and approximately 6.00 carats of diamonds makes the ring as technically impressive as it is visually striking.

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.
