I happen to have some previous knowledge of diamonds from my days of buying/selling estate jewelry, and I can tell you this was a better diamond than I expected. 11-12 points (slightly larger than advertised), with a color and clarity exceeding what was advertised. I would estimate it to be H in color, with a clarity of SI-I, which greatly exceeded my expectations. I purchased it as an engagement ring for my Fiance, and she LOVED it, although she is not a high maintinance girl. I would recomend this ring to anybody who is looking for a low cost promise ring or engagement ring.
