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).

Through reducing the carat size of this diamond (5.12 carats), it's possible you might save a substantial amount of money which will help out with other expenses. The G color of this diamond offers great value, as it is not a member of the expensive premium color grades D-F.

While not quite as perfect a cut as Hearts & Arrows, the Ideal cut of this diamond means it is significantly cheaper, because you're not forking out money for a "perfectly" cut diamond. Girdle thickness (for this diamond the girdle is "Medium to slightly thick, faceted") can play an significant role in the size presented by the diamond, as is explained in my girdle thickness article. If you're a careful online purchaser, this VS1 clarity diamond is relatively safe bet, because the chances are low of it having any inclusions that are visible to the naked eye. Spending $298930 on a stone gets one a well above average diamond, like this one. A tip: sanity check that you're happy spending the money.
