Hi bee, I hope you could give me some opinions. SO and I went to tiffany''s about a week ago and they said they offer SI1 now. I was surprise because the last time we went in there which was last nov late oct they only go below VS2 but she said they had to adjust with the economy so that was quite exciting because I could possibly get a bigger stone if I choose the SI1 for my clarity. What do you think? Do you think it could still be eye clean? We actually havent seen one in person yet so not so sure. What do you think? Thanks bee.
