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).

Girdle thickness (for this diamond the girdle is "Medium to slightly thick") can have an important role in the apparent size of the diamond, as is explained in my article about girdle thickness. If you're checking out this diamond and considering whether to improve another property of the diamond which don't affect size, you may wish to reduce the 1.71 carat size of this diamond. A G color diamond like this one is a great compromise between white pureness and money considerations. If you have got some dollars to spend but do not wish to splurge unnecessarily, this is a great color range to do your searching within.

For $19980, you should be getting a nice stone, so make sure you're plenty critical as you look at this diamond.

While not quite as perfect a cut as Hearts & Arrows, the Ideal cut of this particular diamond results in it being significantly cheaper, because you're not paying a premium for a "perfectly" cut diamond.
