Thank you, Rishav, Himansu and Srinivasa.
@Srinivasa, My DOB is 17 December.
@Rishav, I rang ganeshaspeaks.com and they will be replying back to me on Monday as they have mentioned in the email that my Saturn is not strong.
@Himanshu, According to your experience, how much 5 carat blue sapphire would cost as I noticed that on ebay it starts at very cheap and goes up to thousands of pounds. So, please guide me on this.
