Sterling Silver Sardinian Engagement Ring. The Sardinian ring acquires the meaning of prosperity, wealth and fertility, that is, all the elements that make the couple strong and stable, linked to the land and the family by a precious bond like that of the threads that make up the filigree. The manufacturing of these jewels involves an ancient technique performed entirely by hand without the aid of particular machinery and following a process that exactly follows the traditional techniques of casting, rolling, drawing and twisting. Size 14 (the ring can easily be widened because it is open at the back). It will be sent to you in its own box with a guarantee certificate.
