ABSTRACT:
A jewelry stone assembly comprises upper and lower stone portions which are adhesively attachable to each other at mating surfaces. One or more blind cavities are formed in the mating surface of the lower stone portion and a jewel alone or jewel with setting is dropped into the cavity. Thereafter, clear adhesive is used to attach the upper and lower stone portions at their mating surfaces and the outer surface of the assembled outer stone is further processed, for example by faceting, to produce an outer stone which contains at least one inner stone.
