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).

If you can see the diamond in person or examine high quality photos of the diamond (like the photo for this SI1 clarity diamond), this is where bargains can be had - identifying an SI1 or SI2 stone that is "eye clean" is a fulfilling experience that translates to less dollars spent. The G color of this diamond provides value for your dollar, as it is not a member of the expensive premium color grades D-F. By reducing the carat weight of this stone (1.09 carats), you may be able to save a few dollars that will help out with other costs. For $5880, 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. If your goal in buying a diamond is to get the biggest diamond possible, you can reduce any requirements for other properties of the diamond, for example cut. This Good cut diamond is cheaper than higher grade cuts, because it has somewhat inferior optical appearance.

Don't ignore diamond characteristics outside the four Cs, such as girdle thickness - it can be important due to reasons outlined in my girdle thickness article.
