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. This unique coexistence found only in K2 is why it is called the miracle stone. 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 Zirconia stone When the ring arrives, please gently adjust it to your size. The ring size before adjustment is size 8.5.
