We use real gemstones to create our dice. Striations, patterns, and differences in the mineral are natural and to be expected. Due to the nature of natural minerals, your unique dice may feature differences in colour, texture, and translucency to the set pictures. Importantly, your natural mineral dice are hand-crafted, not machined, and may have faces that are slightly different in size. Engraved numbers may be off-centre, depending on seams or facets of the stone. There may be small differences in balancing between sets, due to the weight of the gemstone. Hard surfaces may damage your stones; please consider this when rolling, and feel free to check out our dice trays or mats. To ensure that these dice travel safely, this set comes with a FREE leather carrying case.
