ABSTRACT:
A gem setting includes a holding body and a gem received therein in a predetermined position, an inner wall face forming a part of the holding body and defining a bore hole therein; a first depression in the inner wall face; and a second depression in a peripheral face of the gem. The peripheral face is received in the bore hole and the first and second depressions are in alignment with one another in the predetermined position of the gem. An elastic connecting member is nested simultaneously in both the first and second depressions for coupling the gem to the holding body. The elastic connecting member and the depth of one of the depressions is dimensioned with respect to one another such that the elastic connecting member is expandable into the depression during introduction of the gem into the bore hole until the first and second depressions arrive in mutual alignment with one another.
