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).

If you've got some dollars to spend but do not want to splurge unnecessarily, this is a great color range to look in. The size of this diamond is 1.25 carats - but make sure you look for the other diamonds for sale with that same 1.25 weight which may have a more desirable combination of properties and price.

While not quite as perfect a cut as Hearts & Arrows, the Ideal cut of this particular diamond results in it being significantly cheaper, because you're not forking out money for a "perfectly" cut diamond.

This SI1 clarity stone represents potential great value, with the proviso it is eye clean.
