Does the HCA work for an OEC if you have all the specs?

I''''m looking at an OEC and have all the specs including Pavilian and Crown angles. Can the Holloway cut advisor still be used on an OEC? If so, it''''s scoring around a 1.8 within FIC.

Yes and no. Mine also came up as a good FIC but it is a really a transitional stone.

Some very pretty OECs are very deep (due to the high crown) and get dinged by the HCA. The large culet is also dinged by the HCA. In old cut stones, the pattern is very important - it should have a mosiac look to it. Have you seen the stone?

Not yet. That will probably be the next step after we finish negotiations.

It will work, but out of roundness is an issue
