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).

To the naked eye, this F color diamond standing alone appears pure white - there is no way to detect traces of color in it using only the human eye without nearby diamonds, or to identify the differences between it and others within the colorless range. Typically VS1 clarity diamonds are the best value "safe" clarity rating in terms of buying online without seeing the diamond - although a lower clarity grading is possible you need to see a good quality photo of the diamond to assess the inclusions for yourself. Weighing up the $21030 price for this diamond, make sure you consider whether any of the property qualities are excessive for your needs.
