This setting technic developt and used from a german company. An open ring (no connection) is cast or made by hand. On booth facing open end a groove is cut into the piece. The stone is placed (rest) into booth grooves.Trough the tension of the ring the stone is hold into place.
For security the metal above booth grooves is burnished until the edge of the stone is enclosed by the metal. This is a very modern style setting technic, which only fit to very strong geometric style rings.
