The gimmel (or gimmal) ring was popular during the 16th and 17th centuries as a betrothal ring. These antique rings were composed of two identical rings which were usually enamelled and inscribed. They fitted together snugly but could be pulled apart and worn separately by each partner. Two halves forming a whole was highly symbolic.
In the 18th and early 19th centuries the fede ring became popular as a romantic love token. these were also known as the 'hand-in-hand' ring and were made of three hoops, of either gold or silver, joined at the back with a tiny connecting rod which allowed the hoops to swivel apart. When closed the top of the fede ring shows two hands clasped together in friendship and when parted they reveal a tiny heart.
The ring in the pictures below, was for sale in our Etsy shop and I think it most probably dated from around the 1970s as that is when the 925 stamp was used in silver jewellery. Prior to the 1970s silver jewellery would generally have been fully hallmarked with the date stamp, makers initials, standard mark and mark of origin.
This particular ring was also quite large, being approximately a size U or 10.5 which was another reason why I thought it was not an antique ring as they had much smaller fingers back then.
