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).

One option with SI1 clarity diamonds is to ask a James Allen member of staff to examine the diamond to check whether it is eye-clean, but make sure you've formed an initial impression yourself from the photo, so you're not wasting time on no-hopers.

If you can view the diamond in the flesh or examine zoomed in 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 fulfilling experience that translates to less dollars spent. 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, you may wish to reduce the 0.73 carat weight for this diamond to achieve that end. While not quite as perfect a cut as Hearts & Arrows, the Ideal cut of this diamond results in it being significantly cheaper, because you're not paying a premium for a "perfectly" cut diamond. Most consumers won't notice the color in this G color diamond, unless the stone is compared side by side with a diamond with say a D color rating (for multistone rings this is important). Do not neglect diamond characteristics beside the four Cs, such as girdle thickness - which can be important for reasons outlined in my girdle thickness article.

For a cost of $2540, this diamond is smack-bang in the middle range of stones used for diamond engagement rings.
