ITEM DETAILS:
Vintage French 18k Gold Tubogas Coil Necklace
A vintage French tubogas‑style coil necklace with a tightly wrapped serpentine construction that runs in a continuous line around the neck. The ribbed coil design gives the piece a flexible, fluid quality while still maintaining a structured, collar‑like silhouette when worn.
The necklace is stamped Breveté S.G.D.G., a French patent mark that was required by law between 1844 and 1968, supporting a mid‑20th‑century dating. The gold‑tone metal retains good overall color with natural surface wear and patina consistent with age and normal use.
If you’re looking for a vintage French 18k gold tubogas necklace or a mid‑century gold collar to anchor a collection, this design offers strong versatility and timeless appeal.
Measures 3/16" wide × 16½" in length. Weight: 24.3 grams.
In good condition; wear consistent with age and use (please see pictures for details). The clasp shows light surface wear and a small area of metal loss near the opening, but it remains secure and fully functional for regular wear.
Reserve: $5,200.00
