the color is great, but the clarity leaves something to be desired. I got a hook up on my gf's gift. I got her 14KW diamond studs. They are F color and a VS2 Clarity, round brilliant cut, 4 prong screw backs. Got it for $345 shipped w/ a certification. That SI isnt the best. Work out the details for the pendent first, then the chain. You can get a chain anywhere. Let us know how it goes.
