I would agree with Lady_snow on the fact it depends on which belief you are going by.

Hold the ring in your hands, and concentrate heavily on what you want it to do. Visualize the object performing its purpose; see it doing its job. Visualize the energies of what you want flowing from your heart and mind, down your arms, through your hands and flooding into the object with your power of intent
