Best Answer

A round brilliant cut stone weighing five carats measures about 11mm at the girdle. A rose cut diamond has fewer facets than a round brilliant, so this number can only be an estimate.

What is the size of a 1 carat diamond in millimeters?

It's impossible to give a precice answer to your question as a carat is an unit of weight, while a millimeter is a unit of area. Depending on how the stone is cut ( the cut of a stone is more a pattern and number of facets, ie: the brilliant cut must a) have a round girdle and b) have at least 56 facets. there have been brilliants cut with up to 146 facets ( to the best of my knowledge). Then there is the matter of shape. An one carat brilliant will have a much different set of measures than a one carat emerald ( rectangular) cut. Finaly there are the variations caused by the cutter himself as he makes decisions on what angles and sizes of the facets themselves ( as long as they are proportionate within the cut) will best show and flatter the stone. With all that said, I have seen one carat brilliants that have ranged from roughly 5.5 to 7 mm across the top depending on depth of cut, size of crown and table ( table = flat, crown = area between table and girdle) and width of girdle ( the ring around the widest part of the edge). I am sorry that this is probably not the exact # you were looking for, but it is the most exact I can give. If you are in the market for a stone, rather than a precise top measure, you will be better off sticking to the 4 C's ; Cut, Carat, Clarity, and Colour. That, a little research on your own ( gotta love the net!) and the help of a reputable jeweler are the keys to best balancing the beauty and the cost of each stone.a typical round faceted 1 carat diamond is 6.5mm or nearly 1/4 inches wide
