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 so 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. We encourage you to embrace the individual beauty of natural precious stones and the age-old process of hand-crafting. Hard surfaces may damage your stones; please consider this when rolling.\nSize of each dice: D4 = 16 mm D6 = 16 mm D8 = 16 mm D10 = 16 mm D% = 16 mm D12 = 18 mm D20 = 18 mm Need a nice GIFT box to pack the dice?
