Hi balaji,
According to your horoscope you are Capricorn ascendant ruled by Saturn. You are born in the Krittika nakshatra ruled by Sun. Currently you are going through Jupiter Mahadasha which will be operational till 16/05/2029.
Placement of Venus in the 3rd house in the sign of Pisces makes Venus Exalted. Venus is being aspected by malefics and has a negetive Drig Bala. You may wear a Diamond / White Sapphire / White Zircon / White Topaz to strengthen Venus. It should be worn in Gold in Right Middle finger on a Friday of a shukla paksha in the hora of Venus.
Thank You
