Recently as I live in Canada, I was researching the grading consistancy of Gemscan versus GIA/AGS, while I wasn''t able to make a definitive decision on that topic I did read on their website some interesting information which I hadn''t considered before.

Note that the cut of a diamond is not the shape of the diamond. The most common shapes seen are round, oval, marquise, pear, emerald cut and heart shape. The most brilliant of these is the round brilliant. The following are some average cutting times for specific diamond shapes:
Round brilliant............2-4 hours
Oval brilliant...............8-10 hours
Marquise shape..........12 hours
Emerald cut................14-16 hours
Any thoughts?
