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.

How big is a 1 carat ring?
A common misconception. Carat is nothing to do with size. Carat is related to weight and therefore a 1 carat stone depends on the gemstone in question and its cut. 1 carat is 0.2g and a 1 carat round-cut diamond is approximately 6.5mm in diameter. Similarly, since CZ is a diamond simulant, a 1 carat round-cut CZ is also deemed to be one that is 6.5mm in diameter but such a stone actually weighs more than 0.2g because CZ is more dense than diamond.

For a complete answer, you must go to this site:RarityOf the 4 C's, Carat Weight is probably one of the most important considerations with respect to rarity, value, and consumer preference. In fact, Carat Weight, or how much the diamond weighs is the most significant value factor in a diamond. Because diamonds by nature are rare, a 2 carat diamond is actually about 3 times more valuable than a comparable quality 1 carat size. Statistically a 1 carat is one in a million diamonds mined, and a 2 carat is one in five million diamonds mined. Therefore, all things considered a 2 carat diamond is really "value priced" based on the rarity factor.PricingLarger diamonds are much more rare, thus commanding a higher price/per/carat. Carat weight affects the value of a diamond by about 10-20% for each step in size difference. Also, "magic sizes" refer to major carat weight categories, for example exactly 1.00 carat, or larger, and can prompt "price premiums". To calculate the price of a diamond you multiply the carat weight by the price/per/carat. For example: if a 1.25 carat diamond was priced at $10,000 per/carat the diamond would be sold for $12,500.* http://www.diamonds.com/education/Carat.aspx
