The invention offers a solution in jewelry manufacturing and production industry. In details, the invention implies mounting stones on a metal base, including pieces of jewelry or bijouterie with stones or gems. According to the described method, each stone pavilion is placed in an appropriate seat, in which the inserted stones are held at least by protruding projections or beads made on the edge of the seats. The invention solves the issue of the densest placement of stones, which are mainly round in view from above or have a round gem-cutting on the surface of the base of a jewelry piece.

A stone setting machine that includes a base structure having a centrally disposed holding aperture, and a holder for a pre-cast setting basket meant to receive a stone. The pre-cast setting basket includes a plurality of prongs meant to be bent to retain the stone. The holder is disposed within the holding aperture. A plurality of slide members are supported over the base structure and meant to bend the prongs. The base structure includes a stationary plate member. A rotatable disc is provided for support by the stationary plate member has a plurality of disc control slots corresponding in number to the number of slide members. A plurality of control pins are received in respective disc control slots and coupled to respective slide members. An actuation mechanism is for controlling the rotatable disc which, in turn, controls the slide members to bend a corresponding respective prong.

An insulator for a test clip is described. The insulator includes a first clip cover configured to removably attach to a top portion of a test clip. The test clip comprises a top portion and a bottom portion pivotally attached to the top portion along a pivot axis. The insulator also comprises a second clip cover configured to removably attach to the bottom portion of the test clip. Each of the first and the second clip cover comprises one or more retaining elements configured to secure the clip cover to its respective portion of the test clip. In some implementations, each of the first and the second clip cover comprises one or more cantilevered retaining segments configured to extend over a portion of the test clip in order to secure the first and the second clip covers to the test clip.
