Unlike traditional polyhedral dice (such as pyramid d4s), these have an asymmetrical crystal or tumbled stone shape (they are often called "crystal d3s" or "tumble dice").
They are designed to stop in one of three stable positions, each marked with a number (1, 2, or 3) in gold lettering (except for the Brown/Gold version, which has white lettering).
Base: The dice have a swirling or pearlescent effect, mimicking the appearance of gemstones.
