K2 stone, the world's strongest healing stone, is a power stone known as the "miracle stone." It is a mysterious natural stone with a gray base and mottled blue spots. The gray base is granite, and the blue spots are azurite. Azurite is known to sometimes coexist with malachite, but it is rare for it to coexist with granite. Because stones like this are only found coexisting in K2, it is called the miracle stone. When viewed from the back, the adhesive has turned yellow, but please be aware of this. It is not visible from the front. The price has been reduced. ⚫︎ Ring Free size Brass Once you receive the ring, please gently adjust it to your size. The ring size before adjustment is size 12.
