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 1.50 Carat Diamonds

The first 1.5 carat diamond has quite a few moderate inclusions and is rated an SI2 clarity-wise. Not bad for a budget option.

Moving right along, the second diamond has no major visible inclusions so it's probably eye-clean, but the cut is pretty horrible as evidenced by both the photo and the "Good" cut rating. It's probably not going to sparkle that well.

At a whopping 1.71 carats, the last diamond has no visible inclusions at all (surprised it's rated an SI1) and has a better cut than the second diamond. I'd be choosing between the first, ultra budget option and the last diamond, the cut on the middle diamond is just too bad.
