I have been looking for a diamond for a while now and have found some nice stones. It is between a couple of them now. They are between 1.33 and 1.52. The larger of the two is in the front running(girlfriend likes the bigger stones)but we are wondering if it''s I color will be noticeable or not. We compared it with stones of the e-f grades and noticed a difference, but set by itself will it be noticeable. The diamond is an ideal cut with an SI1 Clarity. I started out thinking nothing lower than a VVS2 on clarity but there are a lot of very nice SI1 stones out there. Thank you in advance for your response.
