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).

Looking carefully under a scope at an SI1 clarity diamond in person or finding a high resolution image of it (as in this case) is critical to avoiding large eye-visible inclusions.

The G color of this diamond offers value for your dollar, as it is not a member of the expensive premium color grades D-F. If you can view the diamond in the flesh or examine high quality photos of the diamond (like the one for this SI1 clarity diamond), this is where the most valuable deals are to be found - identifying an SI1 or SI2 stone that is "eye clean" is a satisfying experience that pays off in terms of money saved. This diamond's girdle ("Thin to medium") will have an influence on the overall diamond; don't ignore it completely. For any diamond, a cost of $820 puts it in the lowest price group of diamonds, especially for engagement rings.

Several diamond sellers will offer an Ideal cut diamond cut grading, and these diamonds are almost always (as is the case here) perfect with respect to proportions and the overall shape.

If you're checking out this diamond and thinking to yourself that you want to improve other characteristics of the diamond which don't affect size, think about downgrading the 0.41 carat weight of this diamond.
