J.E. Caldwell & Co. 1.30 Carat Purple Sapphire Diamond Stick Pin
A Signed J.E. Caldwell & Co. Stick Pin with Purple Sapphire and Diamond
This elegant J.E. Caldwell & Co. purple sapphire and diamond stick pin is a refined jewel with a rich contrast of color, brilliance, and classic design. The piece centers on a vivid 1.30 carat purple sapphire, round faceted and bezel-set within a white metal frame that enhances the depth of its violet-purple hue. Beneath the sapphire rests a sparkling diamond accent, adding light and balance to the composition.
The design is beautifully restrained, allowing the gemstones to take focus. The purple sapphire offers a distinctive alternative to more traditional blue sapphire jewelry, with a saturated color that shifts between deep violet and royal purple depending on the light. The diamond below adds a crisp point of brilliance, creating an elegant two-stone arrangement that feels sophisticated and highly wearable.
Signed J.E. Caldwell & Co., this stick pin carries the appeal of a respected American jewelry house known for fine craftsmanship and classic design. The gold pin stem contrasts beautifully with the white metal gemstone settings, giving the jewel a refined two-tone appearance. Its elongated form makes it suitable for wear on a lapel, scarf, tie, jacket, or as part of a curated collection of antique and vintage stick pins.
Compact yet striking, this J.E. Caldwell & Co. 1.30 carat purple sapphire and diamond stick pin is a distinctive piece for collectors who appreciate signed jewelry, unusual colored sapphires, and elegant gemstone accessories.

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.
