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).

Budget Round Shape SI 1.25 Carat Diamonds

1.25 carats is sort of a strange carat size - it's a significant diamond in the "no man's land" between 1 and 2 carats. The first diamond on the list is quite cheap but has a moderate inclusion in the center of the diamond.

Add another $1200 and you get a diamond with a smaller scratch in the center, which is probably not visible to the naked eye.

Add another $1200 on top of that again, and you get a massive 7.2 mm diamond with no eye-visible inclusions. Overall, I'd probably pick the second diamond.
