Well, I've decided to keep my demantoid garnet ring after all but first I called Gems TV to find out a bit more about the diamonds in the ring. I was told over the phone that they were S1 and SI1 grading (there are two sizes of diamond in the ring but she couldn't tell me which had which grading). But I can't find any mention anywhere of an S1 (one) diamond grade - only SI (i). What is an S1 grade? And what's the difference between S1 and SI1?
