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).
2.02 Carat Diamond Size on Hand
A typical round diamond with a 2.02 carat size has a width of 8.3 mm; bear in mind that this can change if the cut is shallow or deep. I've used the most common engagement ring size, a size six, in the image; this ring size has an internal diameter of 0.65 inches of 16.5 mm.

Don't make the mistake I made of looking at a potential diamond engagement ring placed on my own, male finger - remember that it is ending up on a usually smaller and more petite female hand, which will make the diamond appear significantly larger.
