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).

The Hearts & Arrows cut of this stone places it in the top 1% of diamonds on the marketplace at the moment in terms of cut quality. This cut is the highest cut offered by James Allen and ensures the highest diamond brilliance. If you are looking at this diamond and considering whether to improve other characteristics of the diamond not related to size, you may wish to reduce the 1.66 carat size of this diamond. Girdle thickness (for this diamond the girdle is "Thin to medium") can play an important role in the apparent size of the diamond, as is explained in my girdle thickness article. For $22750, if you've done your shopping properly you should have a nice stone; ensure that you are harsh in your judgement when you're looking at this diamond. F color diamonds are very colorless, meaning they are part of the pure white diamond range.

Although this VS1 clarity diamond is pretty much guaranteed to be "eye-clean", if you're aiming to reduce expenditure, try checking out SI clarity diamonds. Try to find a diamond that is eye-clean in a photo or when seen in the flesh.
