You know that scene in the Indiana Jones movie where the guys takes out a sword and brandishes it for 10 seconds, and then Indiana takes out a gun and just shoots him?

Just use this.

The HCA is specifically designed, (after the fact, perhaps), to do away with the search for pre-set combinations. One set of angles, will work nicely with another, not so good with a second set. The idea of favorites is actually unattractive to me.

Anyway, take the easy way, which HCA and the search by cut db encourages you to do.

Regards,

Hi Scarleta. I would agree with RegularGuy - there are no pre-sets.

However, if you want some general search parameters to help you narrow it down, try:

Table: 53-58%
Depth: 58-62.3% (or 63%)

The folks here like crown angles between 34 & 35 degrees and pavilions angles just under 41 degrees. The girdle should not vary too much: Medium, Thin-Medium, Med-Sl Thick are all good.

Unfortunately, you just have to go through and plug in numbers to the HCA tool as you find diamonds. Hope this helps.
