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).

This diamond has high quality properties - a color rating of G, combined with a sometimes dodgy SI1 clarity grading - this means you need to check the clarity yourself in the photo.

The Ideal cut means the diamond will shine significantly more in comparison to lower cut quality diamonds, maximizing attractiveness. The G color of this diamond provides great value, as it is not one of the expensive premium color grades D-F. If you can see the diamond in person or examine zoomed in photos of the diamond (like the one for this SI1 clarity diamond), this is where bargains can be had - identifying an SI1 or SI2 stone which is "eye clean" is a satisfying experience that pays off in terms of money saved.

For $44000, if you've done your shopping properly you should have a nice stone, so make sure you're plenty critical as you look at this stone. Girdle thickness (for this diamond the girdle is "Thin to medium") can have an significant role in the apparent size of the diamond, which is detailed in my girdle thickness article. Put this 3.08 carat weight in the right reference frame as you consider your diamond choices - there are for sure other diamonds in the same size range that can provide more with regards to their price and properties.
