Anything under 2 is like a fine wine. I personally can not discern a 1-2 or 4-5 difference. The factor is made up of 4 variables and it may even be that you prefer brilliance and someone else prefers fire, so we advise any stone under 2 as being in the top 3% or so. Regards Ps be sure to us angles over %'s if you can get the info that way. Regards Garry |
