Looking at your horoscope we see that your Ascendant is Cancer and Moon is the Lagan lord. Saturn is the 8th lord and most malefic planet in your horoscope. Shani Sade satti is going on as Saturn is in transit in Scorpio. I strongly feel that you should not wear Iron ring of Shani. Rather do Shani Mantra Jaap and wear a Pearl in Silver on your right hand ring finger. Your moon which is lagan lord and also its mahadasha is going on is weak. We need to improve your moon by doing its remedies and gemstone.
