Hi,
I'm comparing a few hearts/arrows stones at WF and BGD and it's kind of tough to figure out which one would offer the best value when taking everything into account, i.e, the 4C's vs. prices.
The 3 stones at WF all conform to ideal proportions with slight differences in size, color, clarity and prices:

1) WF 1.845 F/VVS1
Light Return: Excellent
Fire: Excellent
Scintillation: Very Good
Spread: Very Good
HCA Score : 1.4 - Excellent - within TIC range
2) WF 1.765 D/VVS2
Light Return:Excellent
Fire:Excellent
Scintillation:Very Good
Spread:Very Good
HCA Score : 1.4 - Excellent - within TIC range
3) WF 1.725 E/VVS1
Light Return:Excellent
Fire:Excellent
Scintillation:Excellent
Spread:Very Good
HCA Score :1 - Excellent - within TIC range
This stone is the smallest (although not by much) but I'm curious as to why the scintillation rating is "Excellent" as compared to "Very Good" for the two bigger ones. The HCA score is 1 which is close to ideal as far as HCA is concerned (if I remember correctly), but I also learned that HCA is a rejection tool rather than a selection tool so I'm not sure if the "Excellent" scintillation rating and HCA score of 1 would give it a slight edge over the two slightly larger stones.
BGD 1.798 F/VVS1:

Light Return:Excellent
Fire:Excellent
Scintillation:Excellent
Spread:Very Good
HCA Score : 0.7 - Excellent - within TIC range
The BGD stone (1.798 F/VVS1) is very close to stone 1 from WF (1.845 F/VVS1) from a technical standpoint and also price, but the Table% = 57.3 which is slightly higher than the upper range of the ideal range of 54-57.
I looked at the hearts/arrows, ASET and idealscope images of these 2 stones and they're both very nice but to my untrained eyes the BGD's hearts pattern seems to be just a tad nicer/cleaner but I can't be sure. On the other hand the WF stone #1 is slightly larger and conforms to all ideal proportions while the BGD stone seems to slightly miss the mark on Table%. Should this be a concern at all? To my eyes the brilliance and sparkle of the BGD stone is pretty incredible. Which one would you pick based on these data? Any insight is greatly appreciated.
