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).

0.53 Carat Actual Size (Princess Shape)

The picture shown on this webpage shows the approximate width of a 0.53 carat size princess shape diamond on the hand of a woman. Carat weight isn't the be all and end all - the type of cut will also influence the apparent size of the diamond; a diamond like this 0.53 carat one will usually be around 4.9 mm typically. While this picture will give you some concept of how massive a diamond will appear viewed on the hand, remember that the size of the ring you choose or need may be significantly larger or smaller than the size 6 in the picture.

Pictures can sometimes be a little dependent on the viewer - I've tried to make this one as clear as possible, but remember viewing the diamond in the flesh may give you a totally different judgement of size to viewing it on the web.
