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).

Actual Diamond Size of a 2.45 Carat Diamond

If you are thinking about how large a 2.45 carat diamond looks when worn, here's a picture to give you an approximate idea. This 2.45 carat round diamond is 8.8 mm in diameter as shown in the image. Don't forget to consider not just the overall size of your hand, but also whether you have long and slim digits or short and pudgy ones. The apparent size of a diamond depends heavily on what it is shown against - her hand - a petite hand will make the diamond appear significantly larger, with the reverse applying as well.
