Allah has put special blessings in some gemstones, such as Aqeeq. Wearing it increases protection and Rizq (sustenance) for the person wearing it. It’s highly recommended to wear a Aqeeq ring in your right hand.
I’m not sure if there scientific evidence that shows their effect. Many believe certain gemstones have healing powers. As for wearing a ring, we believe in the spiritual benefits of it, so it’s not something that can be examined in the lab.
