Invisible setting and methods and tools for effecting same

A mounting for holding a grooved gemstone invisibly to a setting, the mounting having a first end with extensions to receive the gemstone and protrusions extending inwardly from said extensions to fit within respective mounting grooves of the grooved gemstone, the mounting further comprising a holding configuration for lockingly holding said mounting to said setting, wherein the mounting is configured to be deformed upon pulling inwardly about contouring on said setting, said deformation being such as to lever said extensions to push said protrusions inwardly into said groove, and the mounting comprising a concave base portion being flattenable to provide said deformation.

A setting for gemstones comprising a plurality of locations for holding respective gemstone mountings, each location being shaped to close upper protrusions of said mounting into grooves of a grooved gemstone to hold said gemstone to said setting, said setting being contoured to push upper parts of respective mountings inwardly to lock onto said grooves when said setting is pushed downwardly into said location, the setting configured to form an item of jewelry, said item of jewelry comprising said setting and a plurality of mountings, each mounting for holding a grooved gemstone invisibly to said setting, respective mountings having a first end with extensions to receive a respective gemstone and protrusions extending inwardly from said extensions to fit within corresponding mounting grooves of the grooved gemstone, each mounting further comprising a holding configuration for lockingly holding said respective mounting to said setting, wherein said holding configuration is configured to undergo distortion when fitting into said setting, said distortion for said lockingly holding said respective mounting to said setting.
