HELP! I need a carat size chart for emerald cut?

[dashimurzi]

Hi, do any of you know if a size chart exists for an emerald cut diamond that is specific (with uneven numbers).

Like "7 by 5" is a carat, "6.5 by 4.5" is .75 of a carat..how about "6.8 by 4.6" for example? or "6.9 by 4.7"?

thank you!!!!!

The only chart I know of that give dimentions for carat weight is this: http://images.amazon.com/media/i3d/01/actual-diamond-size.pdf

Hope this helps

Hi Dashimurzi, how about this chart?

That''s a good reference chart, Skippy.

Of course it will change because the depth of emerald cuts are all over the place from 60% to 70% and up which means the stone will be smaller as depth increases, not to mention the ratio will change the LxW dimensions too.

Fancy shapes can hold weight in other ways not related to the depth unlike rounds, so doesn't always relate to face up spread/ size.

For the true calculation for fancy stones, I calculate the surface area of the top of the diamond. I find that to be the most accurate representation of the perceived size of emerald cuts. So for emerald cuts, it is the LxW.

I have found this diamond [and other stone] weight calculator useful: http://www.dendritics.com/scales/carat-weight.asp.

BTW, my 11.8x9.9x6.5 EC weighs 6.39 carats, not 5 like some of these charts show.

A Emerald 1 ct. that measures 7 x 5 is a well cut stone. If the stone measures 7 x 5 and was a 1.20 ct. for instance the stone would too deep.
