Art Deco Cartier Agate Blue Enamel and Gem-Set Desk Clock
A Signed Cartier Art Deco Clock with Agate, Blue Enamel, and Black Gem Accents
A striking Art Deco Cartier desk clock featuring a luminous honey-toned agate case, a signed Cartier dial, a vivid turquoise-blue enamel bezel, and four square black gem-set corner accents. Compact, elegant, and richly decorative, this piece reflects the sophisticated geometry and luxurious materials associated with Cartier’s early 20th-century decorative objects.
This exceptional Art Deco Cartier Agate Blue Enamel and Gem-Set Desk Clock is a refined decorative object that brings together natural stone, enamel artistry, and Cartier’s celebrated design language. The clock is formed from a square, softly translucent honey-colored agate case, whose natural cloud-like variations give the piece depth, warmth, and individuality. The polished surface catches the light beautifully, making it an elegant accent for a desk, vanity, mantel, or curated collection of fine objects.
At the center is a silver-tone dial signed Cartier, featuring black Roman numerals and a finely textured guilloché-style center. The gold-tone hands are especially decorative, designed with open circular links and arrow-shaped tips, adding a distinctive jeweled character to the face of the clock. Surrounding the dial is a vibrant blue enamel bezel, decorated with small gold-tone details and stylized Art Deco motifs that create a bold contrast against the soft glow of the agate.
Each corner of the agate case is mounted with a square black gem-set accent, likely intended to create the sharp, graphic contrast so admired during the Art Deco period. These dark stones, set in gold-tone mounts, give the clock a strong architectural presence and emphasize the symmetry of the design. The reverse features a rounded clock movement and a sculptural gold-tone stand with circular supports, allowing the piece to sit beautifully as a small luxury desk or table clock.
Measuring approximately 3 inches by 3 inches, this Cartier Art Deco desk clock is compact in size but visually powerful. It is a wonderful piece for collectors of Cartier objects, Art Deco clocks, antique desk accessories, jeweled decorative objects, and fine designs combining agate, enamel, and gem-set details.

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.
