Art Deco J.E. Caldwell Agate and Diamond Desk Clock
A Jeweled J.E. Caldwell Art Deco Clock in Agate and Diamonds and Enamel
A refined Art Deco J.E. Caldwell desk clock, crafted with a warm honey-toned agate case, delicate diamond floral accents, and an elegant silver-tone dial marked J.E. Caldwell & Co. Compact yet highly decorative, this French-made clock captures the sophistication of early 20th-century luxury design.
Detailed Description
This exquisite Art Deco J.E. Caldwell Agate and Diamond Desk Clock is a beautiful example of decorative craftsmanship from the early 20th century. The clock features a square honey-colored agate body, softly translucent and naturally variegated, giving the piece a warm, luminous presence. Its compact form makes it ideal for display on a desk, vanity, mantel, or curated collection of fine decorative objects.
The front is centered by a refined circular dial signed J.E. Caldwell & Co., a respected American jeweler and luxury retailer known for fine jewelry, silver, and elegant objects of distinction. The dial is enhanced by stylized Arabic numerals, ornate hands, and a decorative border with geometric detailing that reflects the refined visual language of the Art Deco period.
Four floral accents decorate the corners of the agate frame, each set with a small diamond at the center, adding a subtle jewel-like brilliance without overpowering the design. The reverse reveals a French clock movement marked France, supported by a metal stand. The visible age and patina on the back are consistent with a period piece and contribute to its authentic antique character.
Measuring approximately 3 inches by 3 inches, this clock is small in scale but rich in character. It is both a functional decorative object and a collectible luxury accessory, appealing to admirers of Art Deco design, J.E. Caldwell pieces, antique desk clocks, and jeweled objects made with fine natural materials.

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.
