I received a gift from my client....a beautiful heart shaped diamond pendant and according to the GIA certificate, it reads: D, SI1, .76 ct. Upon looking through the 10X loop, I see a noticeable inclusion. Do you know if this is normal to see so clearly with an aid from a loop? This is my first SI, so I don't know what to expect, as usually I buy VVS for a good size diamond. But since this is a gift, I'm happee, happee, and delighted to accept. 
I'll try to post a picture tomorrow.
