Abstract
A gemstone centering device includes a platform for receiving the gemstone and two pairs of arms. The pair of first arms arranged opposite one another above the platform and movable along a first axis. The pair of first arms move between a retracted position and an extended position in which a distance between first gem contacting surfaces of the pair of first arms is less than in the retracted position. The pair of second arms are arranged opposite one another above the platform and movable along a second axis. The pair of second arms move between a retracted position and an extended position in which a distance between second gem contacting surfaces of the pair of second arms is less than in the retracted position. Movement of the pair of first arms is independent from movement of the pair of second arms.
