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).

Usually VS1 clarity diamonds are the best value "safe" clarity rating in terms of buying online without a photo - you can go to a lower clarity grading but then you need to see a high quality photo of the diamond to assess the inclusions for yourself. Spending $17300 towards a diamond gets one a diamond well above the cut, such as this diamond. Just be sure that you and your partner are happy spending this amount of money on a diamond. Girdle thickness (for this diamond the girdle is "Thin to medium") can play an important role in the size presented by the diamond, which is detailed in my girdle thickness article.

The size of this stone is 1.57 carats - but make sure you check out the other diamonds for sale with a similar 1.57 weight that might have a better combinations of properties and price.
