I gather the reason that more stones are not ideally cut is because of a desire for the cutter to avoid weight loss (hopefully with the Sarin cut-optimisation software this can be minimized).

For interest's sake, does anyone out there know what kind of % of weight sacrifice can be involved between a diamond of perfect cut from a good cut?

What sort of difference could this mean in market values (please exclude ideal-fanatic's opinion of value) say in a 1 carat diamond?

The example here is real.
Both these diamonds are possible to cut from this actual peice of rough diamond.

Few cutters could get away with a stone as bad as the .65ct, but most would produce a .55ct to .58ct stone that would be typical of what is out there in the market today.

Could you see the difference - you bet. But when you go into a store that only has these goods, and they have great lighting, then unless you bring your own ideal cut stone with you, you as a consumer will not know the difference.

this is my crusade - to improve the average stone cut quality - not to drive everyone to super ideal cuts.
