We try to photograph the item to look as close to the actual color as possible. Please understand that the appearance may vary slightly depending on your device. Due to the nature of natural stones, there may be inclusions, cracks, chips, dents, black spots, discoloration, etc., and there may be slight variations in size and weight. Please understand. Please refrain from purchasing if you suspect it is a fake, are overly concerned with minor details, or are seeking perfection. To prevent substitution, we cannot accept returns or refunds for reasons such as a different size or a different image after purchase. Please purchase with your understanding.
