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 "Thin to medium") can have an important role in the size presented by the diamond, as is explained in my girdle thickness article. The Ideal cut means the diamond will sparkle significantly more in comparison to lower cut quality diamonds, optimizing attractiveness.

If you're looking at this diamond and thinking to yourself that you want to improve other characteristics of the diamond not related to size, you may wish to reduce the 1.51 carat weight for this diamond to achieve that end. VS is an abbreviation for Very Slightly Included - this VS1 clarity diamond has some minor inclusions which may or may not be easy to see under 10x magnification, but are rarely visible with the naked eye - however it can occur on the odd occasion. For $20000, if you've done your shopping properly you should have a nice stone; ensure that you are plenty critical as you look at this diamond.

F color diamonds are usually described as the colorless diamonds, amongst the purest white diamonds you can get.
