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 0.50 Carat Diamonds
Half a carat is a very popular size point when buying a diamond engagement ring, representing a good compromise between budget and getting a sizeable stone over 5 mm in diameter. The first stone on the list is a real beauty, with no visible inclusions, while also being the cheapest by a significant margin.

The second stone on the list has a visible long and thin defect at the top left of the photo, which may or may not be eye-visible at normal magnification. I'd choose the first one over this one, especially since it is cheaper. Note that it is also the largest of the three stones.
The last stone on the list appears to have some defects at the top right of the photo, although it is the most expensive of the three. I'd still be picking the first stone over the other two.
