Cat's Eye gemstone should be worn on Tuesdays during the ascending moon cycle near sunrise and the minimum weight should be 7 carats. The gemstone should be worn on the middle or ring finger of the working hand and must touch the skin after being dipped in gangajal or cow's milk for 10 minutes. Reciting the "AUM KETAVE NAMAH" mantra while wearing it helps gain respect, especially for creative professionals.
