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).

Although 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. If you are buying blind online, then VS2 clarity is basically the minimumclarity rating you can go for without running a significant risk of picking up a diamond with visible inclusions. This diamond's girdle is "Thin to medium", which plays a impact on the size and sparkle of the diamond, as explained in my diamond girdle article.

$3080 will often allow you to find a good quality diamond, including this particular one. If you are looking at this diamond and thinking to yourself that you want to improve other characteristics of the diamond not related to size, think about downgrading the 0.78 carat weight for this diamond to achieve that end. A G color diamond like this one is a good option balancing extreme white pureness and money considerations. If you've got some dollars to spend but do not wish to splurge unnecessarily, this is a great color range to look in.
