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).

This diamond's girdle is "Medium to slightly thick", which can have a role in the size and sparkle of the diamond, as explained in my diamond girdle page. Several diamond sellers will offer an Ideal cut diamond cut grading, and these diamonds are almost always (as is the situation here) perfect in terms of proportions and the general shape. If you're checking out 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 1.25 carat size of this diamond. Throwing $7590 on a diamond nets you a well above average diamond, like this one. Just be sure that you and your partner are happy spending this amount of money on a diamond.
