Rare Kashmir Sapphire Carved Intaglio Gold Stick Pin, 5.20 Carats, AGL
A Rare Antique Kashmir Sapphire Intaglio, Documented by an AGL Prestige Report
This exceptionally rare antique stick pin features a 5.20-carat natural Kashmir sapphire, intricately carved in intaglio and mounted in gold. Accompanied by an AGL Prestige Report, the sapphire is identified as originating from Kashmir with no gemological evidence of heat treatment.
Kashmir sapphires occupy a distinguished place in the world of important gemstones, admired for their scarcity, historic origin, and characteristically rich blue appearance. This example is particularly remarkable because the sapphire was not conventionally faceted. Instead, it was carefully engraved in intaglio, transforming an already important gemstone into a miniature work of lapidary art.
The carving is incised directly into the sapphire, revealing its details as the stone catches the light and is viewed from different angles. This union of rare gemstone material and antique craftsmanship gives the jewel a depth of character that extends beyond carat weight alone. It belongs equally to the worlds of gemology, antique jewelry, and decorative art.
Set as a gold stick pin, the jewel reflects an era when important gemstones and finely carved intaglios were worn as subtle expressions of refinement. Its elegant scale allows the sapphire to remain the unmistakable focal point while preserving the intimate quality traditionally associated with antique stick pins.
The combination of Kashmir origin, untreated condition, substantial 5.20-carat weight, antique provenance, and intaglio carving places this jewel within an exceptionally limited category. Most significant Kashmir sapphires are encountered as faceted stones in rings or formal jewels; an antique carved example of this size and documented origin is considerably more unusual.
Suitable for wearing on a lapel, cravat, tie, scarf, or displayed as part of an important gemstone or intaglio collection, this jewel offers both visual distinction and serious collector significance.
Collector’s Note
Carved gemstones have been treasured for centuries as personal seals, portraits, symbols, and miniature works of art. In this example, the lapidary carving is executed in one of the world’s most celebrated sapphire materials. The result is not simply an important Kashmir sapphire, but a rare historical object that preserves the artistry and individuality of an earlier period.
Its AGL Prestige documentation provides essential confirmation of the sapphire’s Kashmir origin and untreated condition, while the antique intaglio carving gives the jewel a character that cannot be reproduced by modern cutting alone.

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.
