Abstract
A jewelry item having a rotatable gemstone includes a substantially hollow housing having a bezel and gemstone rotatably mounted on the upper end thereof. Received within the housing is a quartz movement type motor that operates a plurality of interrelated, contiguous gears to rotate the bezel. The gear ratios are such that the bezel will rotate at a predetermined, deliberate speed to achieve a desired aesthetic affect. A switch having a battery mounted thereon is hingedly attached to a side edge of the housing for activating the motor.
