Tank rings are a typical model of the Retro period during and after the Second World War. Heavy, full, geometric shapes, where yellow gold and rose gold reign supreme. Stones are rare, sapphires and rubies synthesis Verneuil know their hours of glory. The aesthetics is very sought after, we are inspired by the chains of the tanks which give the name of “tank” to the bracelets and rings, we draw from the patterns of trimmings and rope, we invent exuberant flowers. Tank rings often weigh a lot, they have a lot of effect on the hand.
