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).

A diamond that is sized at 1.77 carats is usually roughly 7.91 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 1.77 carats of diamond will not always be synonymous with 7.91 mm of diamond. How big a diamond appears does not scale linearly with the carat weight of the diamond, which catches many people out.

If you're willing to try a few things to get a bargain, one thing you can try is searching for a diamond which has a strange carat weight, such as 0.96 carats. Often diamonds with these strange carat weights can be picked up for a bargain because they are not as sought-after even though they are practically the same size as the more popular 1.00 carat diamonds. There are no firm statistics that are universally applicable, but it is generally agreed that the average size of a diamond is around a third of the carat, perhaps a little more.

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.
