2.54 Carat Diamonds
A diamond that is sized at 2.54 carats is usually roughly 8.94 mm in the width dimension. Carat size does not equate exactly to a certain width of diamond, because the diamond may be short and fat, or tall and lanky, meaning 2.54 carats of diamond will not always be synonymous with 8.94 mm of diamond.

Many men when shopping for a diamond engagement ring will look at how big the diamond looks in comparison to their own hand, when they really should be looking at how big the diamond looks in comparison to a female shop assistant's hand who has a hand similar in size to their prospective fiance. Looking around the internet at online diamond stores, you may be tempted to think that a four or five carat diamond is large. You couldn't be more wrong - the golden jubilee diamond is an example of how big diamonds can really be - it is 545 carats, or a weight of more than 100 g, which is about a quarter of the weight of a can of coke.
In terms of diamond properties, the carat weight of the diamond should be considered alongside the many other characteristics of the diamond, in order to find a diamond which is balanced and hence not let down by being of poor quality in one of these departments.
