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).

An untrained eye won't see the color in this G color diamond, except if the stone is held up against a diamond with say a D color rating (for multistone rings this is important). If you are checking out this diamond and thinking to yourself that you want to improve other characteristics of the diamond which don't affect size, you may wish to reduce the 1.71 carat size for this diamond to achieve that end.

The Ideal cut ensures the diamond will sparkle significantly more in comparison to lower cut quality diamonds, maximizing attractiveness. For $14390, you should be getting a nice stone, so make sure you're harsh in your judgement when you're looking at this diamond.
