Hi,
for a recut I pay between 140 and 160 euros a carat.
Sometimes I would need to go back to the cutter after a certification; although tripple x is guaranteed by my cutter, sometimes the hrd may say ex-ex-vg or so. Sometimes we are extremely close, carefull not to loose too much, or worse: jump the rap) so count on lab costs beiling double just in case.

Hi!
Yes I get them done in Antwerp.
Note that the costs are based on recuts, not rough, but this should be similar. China and Russia are out of the question for me, as they do not like to interrupt their production line, not to mention the risk. Besides, I don't have the bulk or sizes needed.
Cheaper is India if you have the right connections and bulk, but xxx is very tricky. China is getting along really well in their cuts, I know of a few producers who have gone over.

There are quite a few levels of triple X cutting..., I assume you are talking rounds. fancy cuts are another world.
I can assure you that cutting to the highest accuracy levels can't be done at the prices mentioned abov or at least I don't believe it's possible because of a few reasons...

The last I knew, the GIA did not use the term "triple X" on any fancy shapes. And you are right, high accuracy in cut requires slowing down the whole cutting process minimally by 50%.

Why? I've never cut a diamond, but was under the impression that they cut so slowly that over cutting was difficult. What sort of tolerances are involved in "High accuracy"? I wish that one of you diamond cutters would go over the details of the process, since many of use are a bit clueless.

Sorry, ofcourse you are correct..., but I automatically translate triple X with triple 0. I am happy you added "minimally". Some accuracy levels will few fold the time vs. generic triple X's. Hoping you agree as well.

Depending on the size of the facet and it's grain direction. But it's quite easy to over cut. Usualy the tolerances are based on the allowed range by the labs. Now depending on the levels individual cutters want..., there is quite a range even if it sounds narrow.

Double if the stone is already close to ideal proportions. Otherwise, triple to quadruple.

Over cutting occurs mainly during brillianteering. Excessive pressure or wheel speed provides the opportunity. Sorry I cannot go into details because I am too busy making a living.

I think it has to do more with accuracy level than a specific stage in the process. Step cuts don't have brillianteering. Don't feel pressure getting into details, I wouldn't want to sway you from making a living..... but accuracy is all about the details
