Thank you for viewing! Material: Natural stone, cost-effective Namibian Pietersite. A must-have for Pietersite lovers! Matte texture, bangle style, a rare shape. It's a very beautiful stone, and the minerals inside the stone are clear, so I think you'll be very satisfied at this price. There are stone marks on the surface, but it's proof of being natural, so please enjoy it if you appreciate natural things! It's said to increase in value from now on. Please collect it while you can. Size: Inner diameter approximately 18 cm It can also be made into an Apple Watch strap for an additional fee. We will provide an estimate. As it is a natural stone, there are natural cracks and color unevenness. Also, it is bound with silicone rubber, so please be someone who can repair it yourself if it breaks. It is very fragile, so please refrain from dropping it or handling it roughly. Please also remove it during exercise. We can also repair it, but shipping and repair fees will apply. We will take a video during packing, so we cannot accept claims for damage. Please take a video when opening the package. Due to the above reasons, we cannot accept returns or claims. Thank you for your understanding.
