Antique Gattle & Co. Natural Black Opal 18K Gold Stick Pin
An Art Nouveau Natural Black Opal Stick Pin with Antique Character by Gattle & Co.
This antique Gattle & Co. natural black opal 18K gold stick pin is a striking jewel centered on a vivid natural black opal with exceptional flashes of green, orange, red, blue, and violet. Measuring approximately 16 mm wide, the opal has a strong visual presence for a stick pin, making this piece far more distinctive than a standard antique lapel pin.
The opal is set in a graceful fan-shaped mount, framed by polished 18K yellow gold that enhances the stone’s dramatic play of color. Its surface reveals a mosaic-like pattern of shifting color, with brilliant flashes that change as the jewel moves in the light. The contrast between the warm gold setting and the luminous natural black opal gives the piece a rich, collectible character.
Marked Gattle & Co. and 18K, this stick pin reflects the refinement of a quality American jeweler. The maker’s mark adds collectible interest, while the natural black opal remains the central value and beauty of the piece. Antique black opal jewelry is especially desirable when the stone displays strong color play, and this example offers a memorable combination of gemstone intensity, gold craftsmanship, and elegant design.
The fan-shaped form gives the pin a sculptural quality while keeping it refined and wearable. It can be styled on a lapel, tie, scarf, hat, or jacket, adding a distinctive accent with historical charm. Antique stick pins were once important accessories for well-dressed men and women, often chosen for their individuality and personal expression. This example stands out for its bold natural gemstone, fine gold setting, and signed maker attribution.
A beautiful choice for collectors of antique stick pins, natural black opal jewelry, 18K gold jewelry, and signed American jewelry, this piece offers both rarity and elegance. Its vivid color, antique character, and Gattle & Co. mark make it a small but powerful jewel with lasting appeal.

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.
