シェーヌ・ダンクル（ネックレス）

The Chaîne d'Ancre is one of Hermès' signature jewels, built on the motif of a ship's anchor chain. Each oval link is bisected by a single horizontal bar, evoking both the strength and the elegance of the sea. Launched in 1938—first as a bracelet—it expanded into necklaces, long sautoirs, rings and earrings, and was later carried across scarves, leather goods and watch designs. For necklaces, the interplay of link size (TPM to TGM) and overall length transforms the look entirely, letting a single design span from a delicate everyday piece to a bold statement necklace.

In 1938, Robert Dumas of the Hermès family is said to have drawn the idea from the anchor chains mooring boats on the Normandy coast (some sources date the concept to 1937). What made it radical was the deliberate use of silver, then unusual in fine jewelry; several sources name the craftsman 'De Percin' as the artisan willing to work the metal (the maker's name varies between sources and is not firmly established). An immediate success on release, it became one of Hermès' most enduring motifs. The anchor chain itself recalls early-19th-century maritime history, when iron chains replaced rope cables, and is widely read as a symbol of stability, connection and attachment.

Link size runs, smallest to largest, TPM (also PPM) / PM / MM / GM / TGM. Commonly cited approximate measurements are TPM ~0.9 cm, PM ~1.4 cm, MM ~1.7 cm, GM ~2.1 cm and TGM ~2.4 cm, though figures shift with the individual piece, era and how it is measured. For necklaces this combines with overall length (choker through sautoir): the same GM reads very differently as a short choker versus a long sautoir. Collectors focus on the triad of link diameter, length and weight—long TGM pieces in particular are scarce and notably substantial.

By far the most common version is sterling silver (925), prized for its clean shine and the character it gains with age. Gold (750, 18-karat) is rarer and appears in yellow, rose and white tones, and diamond-set luxury versions have existed historically. The vintage market is dominated by silver, which sits at a relatively accessible price level; solid gold and diamond pieces are scarcer and tend to command more. Because the bare metal color is central to the design, choosing the cool white of silver versus the warmth of gold meaningfully changes how the piece sits against the skin.

Closures vary—toggle (bar) clasps that play on the motif, or designs that build the fastening into a link itself—and construction differs by era and size. Each link is cast and then carefully polished, and the precision of the house shows in how the central bar meets the link frame, in the joins, steps and finished corners. Collectors weigh the smoothness of the moving parts, the uniformity of the links and the quality of the polish as signs of Hermès craftsmanship. On necklaces, the clasp shape and the placement of stamps can also help indicate the era.

Silver pieces typically carry a '925' metal stamp and gold pieces '750', alongside a 'HERMÈS' logo stamp—though the position and typeface vary by era and may appear on a link, the clasp or elsewhere. Pieces made from 1946 onward use a letter to indicate the production year, and the format changed over time: broadly a bare letter (c.1946–1970), then a letter in a circle (c.1971–1996), then in a square (c.1997–2014), with a revised system thereafter (boundary years vary between sources). These are clues for dating, not proof of authenticity on their own.

The following are general observation points only and do not guarantee authenticity—always seek a professional for any final judgment. Commonly cited cues are: (1) whether stamps are deep, even and crisp (light, shallow or rounded strikes are flagged as cautions); (2) whether the metal is genuinely 925/750-grade with appropriate heft (unusually light pieces are a caution); (3) construction quality such as uniform links, smooth moving parts and finished surfaces; and (4) consistency of date letters and stamps. These should be read together rather than relied on individually. This portal provides neutral third-party information and does not perform appraisal.

Prices vary widely with material (silver vs. gold), link size (TPM–TGM), length, era, condition and accessories, so we give no specific figures here (any market level is an estimate, not a guarantee or investment advice). As a general pattern, silver in medium-to-small links is relatively accessible, while solid gold and long TGM pieces tend to be scarcer and dearer. When choosing, start from whether the piece is for everyday wear or as a centerpiece, and ideally check the drape on the neck, the weight and the presence of the links in person. Layering potential and coherence with other Chaîne d'Ancre pieces are also worth weighing.

Silver in small-to-medium links works as an easy everyday piece, reading well over a shirt or knit. Larger GM–TGM links carry real presence and suit being the focal point of a simple outfit. Choker lengths frame the neckline, while a sautoir lengthens the vertical line and pairs nicely with tailoring. Matching the metal and link feel to bracelets or rings from the same family creates a cohesive look. Deliberately mixing silver and gold is a more advanced move; to keep it foolproof, start by sticking to one metal that flatters your skin tone and the palette of your clothes.

Silver tarnishes (sulfides) readily from sulfur in the air, so after wear, wipe off oils and sweat with a soft cloth and restore the shine with a dedicated silver cloth. Because abrasive cloths can wear down stamps, avoid scrubbing the hallmarked areas hard. Store it sealed against air in a zip bag or anti-tarnish paper, and keep it away from hot springs, pools, perfume and hair products. Gold is comparatively hardy but still scratches, so store it apart from other hard metals. Grime tends to gather in the gaps of the moving links, so lift it gently with a soft brush.

What made the Chaîne d'Ancre radical was placing silver—then unusual in fine jewelry—at center stage. Hermès began as a harness maker, and turning another humble tool of utility, the sea anchor, into adornment sits squarely with the house's love of functional beauty. The anchor-chain motif did not stop at necklaces; it later spread to scarves, bag hardware and watch designs, growing into a kind of crest that runs across the brand. That a seemingly simple repeating pattern has stayed fresh for more than eighty years owes much to its versatility.
