Abstract: A set of gem-like jacks for playing the game of jacks, the jacks being adapted to form in combination with a band of resilient material having a row of holes therein a bracelet or other article of jewelry. Each jack is molded of transparent plastic material to form an opposing pair of four-sided pyramids having triangular sides and a common square base, the peaks of the pyramids and the diagonal corners of the base having small balls integral therewith to satisfy the functional requirements of a playing jack. Because of internal reflections from the triangular sides of the jack and its external geometric form, the jack simulates the optical properties of a multi-faceted gem. To form an article of jewelry, jacks are combined with the band by snapping a ball of a jack into a band hole, the hole dilating to admit the ball and then resuming its normal diameter to trap the ball and thereby retain the jack on the band.
