Hematite rings
The hardness of hematite is 5.5 - 6.5, glass is 6.5. Round beads is good, but the ring made into a thin side is easy broken, you can compare it with the same glass ring. So please take care of your hematite rings :)
- You don't have to take off the ring when you take a shower because they can be waterproof.
- They not metal, break easily, it doesn't like to meet the floor.
