Hello,

I''ve read some previous posts in the forum that some of the experts on board prefer a minimum LGF% of 75% for a round diamond.

My stone comes with an AGS certificate, is it the number as appeared at the pavilion of the diamond plot in the certificate? Do GIA and AGS measure/interpret this number in the same manner?

Yes it is the number that appears on the pavilion diagram, GIA round this figure whereas AGS do not.
