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).

Actual Diamond Sizes on Hand of a 1.62 Carat Diamond

A typical round diamond with a 1.62 carat weight has a width of 7.7 mm, although this can vary slightly depending on the cut. The hand of the woman pictured has long and thin fingers - which may not be what yours look like - if they're not, bear in mind that the ring you buy may look quite different when worn. The apparent size of the diamond and ring can be affected by whether you have thin or thick digits, as well as by the length of your fingers. If you are stressed about how expensive diamonds are but still really want one, here is one piece of good news - the diamonds often appear bigger once placed on a hand, especially if her hand is on the smaller side.
