A French silver ‘tank’ ring, circa 1940, set across the front with four synthetic (flame-fusion) sapphires.
Tank rings were especially popular in France in the 1940s, during and immediately after the war. The name comes from their resemblance to the heavy, mechanical forms of military tanks - stepped sides, rounded edges and a deliberately substantial feel.
The best-known examples are made in thick 18K yellow or rose gold, but silver versions were also produced under the Occupation, when gold was strictly rationed and platinum requisitioned for military use.
With materials scarce, synthetic stones such as flame-fusion sapphires became widely used and are now closely associated with tank jewellery.
Ring size: UK G / US 3½.
