A non-periodic, self-similar, quasicrystal pattern – this is geometry at its loveliest. Penrose tiling is both a fascinating mathematical puzzle and beautiful art. Its aperiodicity implies that a shifted copy of a Penrose tiling will never match the original, making it unique in an interesting way. The image is printed on a translucent medium in order to give the 1" pendant a slightly luminescent look. The back is sealed with a jewelry-grade resin and is water resistant (although you should still not wear it swimming or in the shower). The bail is silver-plated and the pendant is hung on your choice of an 18" black cord, silver twist chain, or silver link chain.
