#Necklace #Accessories #NaturalStone New item. This is a natural turquoise and a tornado ring made of terahertz, which is said to be good for health. It's a ring with a contrast between jet-black jewelry terahertz and shining turquoise. It's a nice free size! Although it's black, as you can see, it shines brightly with the gorgeousness of turquoise. It shines like a black diamond. The beautiful blue color is like a bluebird. And it's healthy! It's a wonderful piece of jewelry.
