  • Reversible and interchangeable jewelry
    Patent number: 6550276
    Abstract: An article of jewelry with ornamental male and female inserts that are reversible relative to their frame. The inserts form an opening on top to accept wire from a balled wire attached to the tubing on the frame. The balled wire allows the inserts to be flipped easily, while a wire, passing through the tubing, is the axis of rotation. A spring wire is attached to the bottom of the frame and fits into a notch formed by the mating inserts to secure the inserts in place. A stop is positioned on the back of the frame to prevent the inserts from extending beyond the back of the frame.
