Abstract: A ring insert assembly comprising a pair of rings for accommodating an engagement or other ring therebetween is provided. The ring insert assembly includes a first ring and a second ring spaced from and substantially parallel to the first ring. The rings are interconnected by means of one or more spacing elements or bars such that the space between the two rings of the insert assembly can receive and accommodate a third ring, such as a solitaire, therebetween. One or more hinge assemblies are fixed to the first and second rings, and preferably to the spacing element, for selectively closing off the opening between the rings through which the third ring is inserted.
