Sterling Silver Color Change Zultanite Ring Size 7, I purchased this in Mexico, I have to assume it's totally lab created however it's truly gorgeous and the workmanship is phenomenal. This definitely changes color, it's set sterling silver and I don't believe there is any rhodium on this as I've never purchased Mexican silver with rhodium. You will see these lab rings all over the internet however they're all rhodium coated (I detest it haha) never worn. This elegant silver ring features a stunning gemstone centerpiece, perfect for adding a touch of sophistication to any outfit. The sleek design and shimmering silver finish make it a versatile accessory for any occasion.
