Materials: Natural Stone Size: Inner diameter approximately 16cm (Please note that there may be slight variations due to amateur measurements.) This is a design bracelet using natural stones, as shown in the image. Natural stones used: ◆ Onyx Cut ◆ Approximately 9mm x 7mm ◆ Terahertz ◆ Approximately 10mm ◆ Crystal Cut ◆ Approximately 8mm ※ Silicone rubber used ※ Brass spacer used The materials were purchased between 2024 and 2025. I love natural stones and have purchased them. I made this design bracelet because I wanted to wear it myself. I am selling it because I have too many now (*..)" I used it to check the product and for photography upon arrival, but there are no noticeable scratches or stains (*..)" I try to take pictures that are as close to the actual colors as possible, but the colors may differ slightly depending on the shooting conditions. Depending on the item, there may be chips, dents, black spots, etc., characteristic of natural stones, from the time of purchase. Please refrain from purchasing if you are sensitive to these, as it is stored at home by an amateur. I am also listing it on other selling sites, so please contact me if you are interested (*..)" Thank you for your trouble. Thank you very much (*..)"
