HCA results

[bdgr4evr]

mr holloway:ive put several stones ito your program and have a question about the output...can the naked eye see the difference between the results in the different grade levels..ie a towkosky cut has an hca level of.3 i think whcih is excellent...lesser cuts may still fall in the acceptable range with a different numerical result....can we see a diference inter and intra classificationthanks

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.

Ps be sure to us angles over %'s if you can get the info that way.
