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).

Put this 2.50 carat weight in the right reference frame as you weigh up your purchasing options - there are going to be other stones in the same size range that may provide more with regards to their cost and properties. The cut rating of this diamond (Premium) has it smack bang in the middle of the road between quality of cut and diamond pricing considerations. Typically VS1 clarity diamonds are the most affordable "safe" clarity grading for purchasing online without seeing the diamond - you can go to a lower clarity grading but then you need to see a high quality photo of the diamond to analyze the inclusions for yourself.

For $41290, if you've done your shopping properly you should have a nice stone; ensure that you are harsh in your judgement as you look at this diamond.

This diamond's girdle ("Slightly thick") will have an influence on the overall diamond; don't ignore it completely. F color diamonds are pretty much colorless - they are part of the pure white diamond range.
