Quick and Easy Buying Guide
Carat weight: 1 carat = 200 milligrams = 6.5 mm diameter. Doubling weight doesn't double diameter.
Diamond clarity: FL/IF/VVS/VS = super expensive, near perfect. SI = best value if you can check a photo for obvious inclusions (defects).
Color: D-G = colorless, expensive, only if you have money to burn. H-J = best value. Can go lower in gold metal settings than white metal.
Cut: Better cut ratings let more light into a diamond, making it sparkle more. Very important property, don't skimp here.
Set a budget and minimum cut (Premium). Go J color for gold and I/H for white metals. Go searching for SI1/SI2 clarity diamonds at James Allen. Pick a diamond with small/no inclusions. Choose a ring setting and buy it risk-free (60-day returns).
2.31 Carat Diamonds
2.31 carats in a diamond gets you around 8.66 mm of diamond, give or take. 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 2.31 carats of diamond will not always be synonymous with 8.66 mm of diamond.

If you like playing with numbers, one analysis method you can use for examining diamonds is to divide the cost of the diamond by the number of carats to get the cost per carat metric. How big a diamond appears does not scale linearly with the carat weight of the diamond, which catches many people out.
Because diamonds with the carat weight of one or two carats are very very popular, it's common for shops and online stores to raise the prices. You can save money by looking for diamonds which don't have the sizes.
God forbid that this should be a problem for anyone, but it may be that the diamond, once it actually put on the fiance's hand, may appear to be too big and unwieldy. Make sure to take this into account when you're shopping around.
If you're umming and ahhing about whether to get a diamond or another precious gemstone, a relevant piece of information regarding their carat size is that the stones have varied densities, leading to different sizes for stones of the same weight. 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.
First-time diamond buyers who are in a hurry often just focus on the diamond carat size, which is a big mistake - other properties such as the clarity of the diamond are important in getting a diamond which is attractive not just in terms of its size, but also its appearance.
