[About product images] There may be slight differences in color tone, etc. due to differences in the shooting environment (light intensity, color temperature, etc.), the customer's confirmation environment, and differences in the computer environment. Also, since the photos are taken in a brighter environment than usual, the color tones and play-of-color effects may appear more vivid. Especially when shooting play-of-color effects, we also adjust the angle of the light. Some minerals, such as fluorescent minerals and fine minerals, are photographed using special environments and equipment. [About the offered products] There are individual differences depending on the product. Also, because it is a natural material, there may be cloudiness, scratches, cracks, inclusions, etc. Since the quality of products created by nature is not constant, we carefully select products with a certain range of quality that match the products we sell, but there may be cases where the human standards for determining quality do not match the customer's standards.
