#Necklace #Accessories #NaturalStone New item. This is a Terahertz tornado ring, said to be good for health. It's a jet-black piece of jewelry. It's a ring with a contrasting shine of Terahertz. It's a convenient free size! Although it's black, as you can see, it shines brilliantly. It has a sparkle like a black diamond. Also, although it's black, it's jewelry that is never dull. And it's healthy! It's a wonderful piece of jewelry. It's a set of two.
