Patent ID: 6889525

Claim:
A ring and a mounting thereon for a plurality of gemstones comprising: a ring segment having a break creating completely separate ring ends, said ring ends forming a pair of shanks, said break extending between distal ends of said pair of shanks wherein said distal ends are entirely detached from each other, a pair of upstanding flexible arms bracketing opposite sides of said break, each flexible arm of said pair of upstanding flexible arms having a base end and an opposite free end, each said flexible arm mounted at its base end to a corresponding distal end of said distal ends of said pair of shanks, a first gemstone forming a keystone mounting in compression sandwiched between said free ends of said pair of upstanding flexible arms, wherein the compression is solely due to compression of said ring ends by the resilient biasing of said ring segment urging said ring ends together and acting on said first gemstone solely via said pair of upstanding flexible arms, a second pair of upstanding arms mounted at base ends thereof to said pair of shanks so as to be disposed, one on each said shank, on opposite sides of said pair of upstanding flexible arms so as to form a first pair of gemstone receiving cavities adjacent to said keystone, on opposite sides of said pair of upstanding flexible arms, between said second pair of upstanding arms and said pair of upstanding flexible arms, second and third gemstones mounted in said first pair of gemstone receiving cavities in compression between said pair of upstanding flexible arms and said second pair of upstanding arms, wherein a reactive force acting outwardly of said keystone, reactive to a compressive force on said keystone resulting from said compression of said keystone, is distributed via said pair of upstanding flexible members as a distributed force acting in compression on said second and third gemstones.
