Uniquely mating jewelry items made from gems

A uniquely mating jewelry item comprising:

• a first stand-alone jewelry piece including:
• a first opaque gem part which has been cut along a separation line from a gemstone, said first gem part having:
• a first outer surface with one of a kind, naturally occurring markings thereon, and
• a first mating surface different from said first outer surface and extending along and to one side of said separation line, and
• a first jewelry holder secured with said first gem part for holding said first jewelry piece on a support such that said first outer surface and said first mating surface are exposed and visible;
• a second stand-alone jewelry piece including:
• a second opaque gem part which has been cut from said gemstone, said second gem part having:
• a second outer surface with one of a kind, naturally occurring markings thereon, and
• a second mating surface different from said second outer surface and extending along and to an opposite side of said separation line, said second mating surface being in an identical complementary shape and dimensions to said first mating surface so as to recreate said gemstone only when said second mating surface is placed in an end to end abutting relation with said first mating surface, and
• a second jewelry holder secured with said second gem part for holding said second jewelry piece on a support such that said second outer surface and said second mating surface are exposed and visible;
• and
• said naturally occurring markings on said first outer surface of said first opaque gem part are capable of matching with said naturally occurring markings on said second outer surface of only said second opaque gem part and only when said first and second mating surfaces are in said end to end abutting relation so as to provide only one possible combination of said matching.
