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).

If you're buying blind on the Internet, then VS2 clarity is basically the lowestclarity rating you can go for without carrying a significant risk of picking up a diamond with visible inclusions. The difference between any adjacent colors in the D-E-F range can only be detected in a specialist laboratory environment, with the significance that this F color diamond is not distinguishable when compared with diamonds rated one color either side of it.

If you're checking out this diamond and considering whether to improve other characteristics of the diamond which don't affect size, you may wish to reduce the 0.64 carat weight for this diamond to achieve that end. This diamond's $2160 cost is a substantial chunk of money for most people, but it does lead to a nicer and bigger stone than if you spent a few hundred dollars. Many different 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.

The girdle of this diamond ("Thin to medium") has an influence on the diamond; don't ignore it completely.
