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 Ideal cut rating indicates it has very good proportions and very good or better symmetry and polish ratings. If you eyeball this 1.05 carat stone and immediately say, "that carat size is too small", ponder whether you can compromise by lowering another property, for example color or cut in order to go for a bigger diamond. Spending $5660 towards a diamond gets one a diamond well above the cut, like this one. A tip: sanity check that you're happy spending the money. SI stands for Slightly Included, which means this SI1 stone contains inclusions that are definitely visible at a zoom level of ten times and may often be visible to the naked eye, but which offer the potential for bargains if they're not. There is a blank in the girdle description for this diamond - it is possible for a diamond to have no girdle, known as a knife-edge girdle.

A G color diamond like this one is a great compromise between white pureness and money considerations. If you've got some dollars to spend but do not want to splurge unnecessarily, this is a sensible color range to do your searching within.
