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).

Let us not be too particular; it is better to have old secondhand diamonds than none at all. Mark Twain .

This diamond has a girdle described as "Thin to medium", which plays a role in the size and sparkle of the diamond, as written about in my diamond girdle article. If you're looking at this diamond and thinking to yourself that you want to improve other characteristics of the diamond not related to size, you may wish to reduce the 0.34 carat weight of this diamond. Most consumers won't see the color in this G color diamond, except if the stone is held up against a diamond with say a D color rating (for multistone rings this is important). Despite the fact this VS2 clarity diamond is pretty much guaranteed to be "eye-clean", if you're aiming to save some money, you should check out SI clarity diamonds. Try to find a diamond that is eye-clean in a photo or when viewed in person.

Several diamond sellers will provide an Ideal cut diamond cut grading, and these diamonds are usually (as is the situation here) perfect in terms of proportions and the general shape. By using only $680 on the diamond, you can save more money to put towards other costs such as the wedding.
