This is a genuine Native American Indian jewelry buckle, made by a Hopi artist. There are engravings and stamps on the back, but the artist's name... I'm sorry, I don't have enough knowledge to know the exact name. However, it is a piece recognized as authentic Native American Indian jewelry. Below are the measurements. Please note that these are amateur measurements. Maximum width: 7.5cm Maximum height: 5cm Compatible belt width: up to 38mm Weight: 62g That's all. I collect various pieces of Native American Indian jewelry as a hobby, and this is one of the items I've collected. It's a classic design, but the quintessential Hopi design, often decorated only with silver, makes it easy to coordinate and wear. The seller remembers paying nearly 35,000 yen for this new buckle about 5 years ago. I'm selling it because I have too many buckles and belts. I plan to list more buckles and belts, including Native American Indian jewelry, from time to time. Please feel free to take a look at my other listings. I have polished and cleaned it with a silver cloth before listing. Therefore, I believe you can use it comfortably. Thank you.
