Thank you to those of you that take the time to post such valuable information. Here's the issue, I'm on a budget and am trying the decide between the following 2 diamonds off the internet: ---------------------------------------------------- Shape: Round Brilliant Carat weight: 0.42 Measurements: 4.86-4.89 x 2.96 mm Cut: Ideal Color: F Clarity: SI1 Characteristics: Crystal, Cloud Depth %: 60.6% Table %: 55.4% Crown Angle: 32.5 deg. Crown Height: 14.4% Pavilion Angle: 40.9 deg. Pavilion Depth: 42.9% Symmetry: VG Polish: EX Girdle: Thin to medium, faceted Culet: 1.2% Fluorescence: None $702 -------------------------------------------------------- Shape: Round Brilliant Carat weight: 0.41 Measurements: 4.83-4.90 x 2.93 mm Cut: Ideal Color: G Clarity: SI1 Characteristics: Twinning Wisp Depth %: 59.9% Table %: 58% Crown Angle: 33.4 deg. Crown Height: 13.8% Pavilion Angle: 40.8 deg. Pavilion Depth: 42.8% Symmetry: VG Polish: VG Girdle: Thin to medium, polished Culet: None Fluorescence: None $643 ---------------------------------------------------------- I'm told that both diamonds are eye clean. The color and carat sizes are close enough to each other that I wouldn't notice a difference between the two. I care most about cut and would like the best cut stone. Both score well on the HCA (0.7 and 0.9 respectively), but I just can't decide between the two. Any opinions or insights? Thanks in advance, George

To be honest I dont really like the crown angle on either one. ........... Karl has joined the diamond trade and is now posting as Karl_K

The crown angle is much more shallow than the norm that we see here, but the HCA doesn't seem to punish for that, and that is what the HCA is good at -- looking at the combo of the crown and pavilion. I didn't have time to run the numbers, but are those HCA using the angle and not the %? It is much more accurate with the angle, so make sure you''ve run it with angles and ignore the % since you have the angles.

d2891 Rough Rock Total Posts: 2 Last Post: 12/23/2004 Member Since: 12/22/2004	Thank you for your replies. Yes, they are both from the same vendor (Blue Nile). I don't have any ideal-scope or H&A images (I don't think I can get them from Blue Nile). I was concerned about the crown angles as well, but wasn't sure how big of a deal it was. Also, the HCA scores given were calculated using the angles and not %. The AGA cut grade for both diamonds was a 1B. Any further suggestions? Thanks again, George

At first, I thought I'd be an relatively easy fan of #1...for $60, you're getting an F over a G; since I've been reading here, I've gotten a soft spot for Fs. I picked a G for my wife, though. Then I ran the numbers. Though both HCA scores are similar, and I wouldn't readily recommend a .7 over a .9, or vice versa, counter-intuitively, the .9 and stone #2 does score for 4 "excellents," including 1 for spread, as over option #1, with 3 excellents. I like the 4 Exes. I'd consider going to a shop that has both Gs and Fs, looking at them, and seeing if you can tell one whit bit of difference. If you can't, the choice could be easy again, and you could consider going for #2 more readily, especially given your prediliction of cut above all. But, I'm guessing there is an inherent difference between F & G, that you will see it, and you're back where you are. Sorry to not be helpful at all, but I hadn't heard these comments, and maybe something here will clarify something for you. Best wishes, and happy holidays!
