Hi all,
My boyfriend has proposed to me with an engagement ring with the following specs:
My boyfriend and I are first time diamond buyers.The jeweler told us that this is an ideal cut.However, after I googled about ideal cut, I found that GIA and AGS have different cut grading systems and that AGS has stricter parameters.According to the AGS cut grading system my diamond is an AGS 1 grade diamond due to the Pavilion Depth (44%) and the Pavilion Angle (41.4 degrees) are slightly outside the upper limits of the ideal range which are 43.8% and 41.2 degrees, respectively.Yet, GIA has graded this diamond as Excellent.
Further, I found that some websites say that the total depth of 62.7% is the upper limit of the ideal range but some websites say the upper limit should be 62.5% or even 62.3%.I also noticed that a 2 carat round diamond should have a diameter of 8.2 mm and the length should be 4.9 mm but the average diameter of my diamond is 8.05 mm and the length is 5.05 mm.Does it mean that my diamond is a deep cut diamond?
I've also tried the specs with HCA and the results are as follows:
Light Return: Good
5.1 - Good - Only if price is your main criterion.
What does this mean?Is it good or bad?
I have told my fiance about the results of my research.He said he is happy to exchange it for me and is willing to pay more for an ideal cut diamond since I am going to wear it everyday for the rest of my life.Some say untrained people will not be able to tell the difference between an AGS grade 0 and an AGS grade 1 and that diamonds with proportions with the range of AGS 0 and 2 are considered very fine cut and provide exceptional brilliance.Our question is: will an AGS grade 0 ideal cut diamond look significantly different from mine (AGS grade 1) in terms of fire, brilliance and scintillation?Is it worth to pay more for an AGS 0 grade diamond?
