Hi everyone
I have just recently bought a round brilliant loose diamond to put on an engagement ring once I find the right design
. I was pretty happy with the stone as on paper it seemed like a good buy with a triple ex score on the GIA cert and a excellent cut based on the AGS proportion chart. However after running the specs into HCA program it has given the diamond a 4.2 score (Good). I would like to ask if anyone can shed some light into why this diamond may have a low HCA score and with the attributes listed below, what maybe some of the negative/positive aspects of this diamond? I have read on a few sites about the HCA being biased towards certain attributes but i would just like to know other peoples opinions with the specs of this particular diamond.
From looking at other diamond specs i have noticed that the crown height is quite low and the pavilion angle is pretty steep. However i am not sure if these are negative aspects of this diamond as a whole.
I have seen the diamond with my eyes however I have never been great at differentiating diamonds with my eyes and to be honest I could barely notice the differences on all the diamonds that have been shown to me. My partner however has much better eyes then i do and may notice much more. I wish i could bring her to see the diamond prior but then it wouldn't be surprise!
Measurements 7.28 - 7.34 x 4.37
Carat - 1.4
Colour - E
Clarity - IF
CUT - Excellent
Polish - Excellent
Symmetry - None
Fluorescence - None
Table - 59%
Crown height - 12.5%
Pavilion Depth - 44.5%
Total Depth - 59.8%
Crown Angle - 31.5
Pavilion Angle - 41.8
Lower girdle / half facet length - 80%
Girdle Thickness - 3%
Star length - 45%
Cutlet - None
Thanks
