---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- Corundum, a mineral composed of aluminum oxide crystals, has special names depending on its color. Red varieties are called rubies, while those of other colors (blue, yellow, brown, light pink, etc.) are called sapphires. Both are second only to diamond in hardness. Rubies are also known as the birthstone for July. This product consists of wild, untamed gemstones with a variety of shapes (see image). *Due to the nature of batch processing, some stones that do not meet the standards may be included, so we have included a slightly larger quantity. *No jewelry processing has been applied. *Since this is a random selection, if you are not satisfied, please contact us through your "Order History" and we will issue a refund.

[Regarding product images] Due to differences in shooting environment (lighting intensity, color temperature, etc.) and the customer's viewing environment, as well as differences in computer environments, slight variations in color tone may occur. Additionally, since we photograph in brighter environments than usual, the colors and iridescence may appear more vivid. We also adjust the angle of the light, especially when photographing iridescence. Some minerals, such as fluorescent minerals and microminerals, are photographed in special environments and with specialized equipment. [About the products offered] There may be individual differences between products. Also, as these are made from natural materials, there may be cloudiness, scratches, cracks, inclusions, etc. Because the quality of products created by nature is not consistent, we select products that are suitable for sale while allowing for a certain range of quality. However, there may be cases where the standards of humans judging quality do not match those of our customers. If you are not satisfied, please return the item through your "Order History." We will handle the return honestly in accordance with Amazon's policies.
