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.

Jewellery history: Retro jewellery is characterised by the use of yellow gold, the development of 3-D volumes and the rarity of precious stones. Here we have a perfect example of these jewels: a large volume, the use of synthetic rubies – making up for the lack of precious stones available on the market after the War. The Second World War had a considerable impact on jewellery fashion at the time, sweeping aside the taste for ‘white’, the geometric ‘flat’ and the abundance of gems of the Art Deco period.
