Thank you for viewing! This is an impactful silver ring featuring a rare white buffalo (white turquoise) stone. The material is 925 silver. The inner diameter is approximately 55mm, which I believe is about a size 14-15. There is a crack on the back of the stone's setting, but it appears to be from the time of manufacture. It is securely connected to the ring (see photo 9). Please understand that there may be some scratches and oxidation due to its vintage nature. I have lightly polished it. The ring part is also thick and powerful. I bought it because I liked it, but it doesn't fit my finger, so I haven't worn it much. There is some wear and tear, but I think it's a beautiful item. (This is just my personal opinion; please check all the photos before purchasing.) *From Google: White buffalo, mainly mined in Arizona and Nevada, is a stone that has been cherished by Native Americans. It is made of 925 silver (sterling silver), with a silver purity of 92.5%. It may be a vintage item handmade by Navajo artisans. This stone was named after the phantom white buffalo, which is said to be born only one in a million. ❈Please be sure to read the profile. ❈By purchasing, I will assume you have read the profile. ❈Prices will be lowered and raised irregularly. ❈No claims and no returns, please. ❈Immediate purchase is welcome ⭕️
