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).

An untrained eye won't see the color in this G color diamond, except if the stone is compared side by side with a higher color grade diamond (for multistone rings this is important). Many different diamond sellers will provide an Ideal cut diamond cut grading, and these diamonds are almost always (as is the case here) perfect in terms of proportions and the general shape. Typically VS1 clarity diamonds are the best value "safe" clarity grading in terms of purchasing online without a photo - you can go to a lower clarity grading but then you need to see a good quality photo showing the diamond to assess the inclusions for yourself. This diamond has a girdle described as "Medium to slightly thick", which can have a impact on the size and sparkle of the diamond, as written about in my diamond girdle article. At a price of $3200, this diamond sits firmly within the normal range of diamonds used for diamond engagement rings.

If you eyeball this 0.77 carat stone and think to yourself, "that diamond is too small", consider whether you can compromise by lowering other properties, for example color or cut in order to get for a larger diamond.
