FIC rating

[captkirk]

A diamond with a FIC rating of 0.8...is this good? Ideal or not? It is a H&A round. What''s everyones opinion???
thanks

Basically, it means that the HCA score is 0.8 which is fine. Anything under 2 is great with some very discriminating PSer's prefering theirs to fall between 1 and 2. The HCA is just a weeding too, after all. FIC means the stone is more tilted towards having more fire versus a TIC (balanced between white light & fire), and BIC (tilted more towards brilliance/white light). There are also a bunch of PSers here who are crazy for fire and would love FICs.

HCA - TIC, FIC, BIC

Was reviewing this post and decided to plug the numbers of my new stone into the HCA.

Oddly, when I enter the angles of the crown and pavillion into HCA as degrees, I come up with a 1.7 (Excellent for TIC)

However, when I enter the same angles as percentages, I get 2.1 (very good)

Needless to say, it''s confusing...Any thoughts??
THANKS

Do a search to confirm but I have read that angles are more accurate to use. I would go on the result ou got by using angles.

Oh goodie! Cause that scores 1.7 and I like those numbers better.
