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).

1.57 Carat Princess Shape Diamond Actual Size

The precise size of a 1.57 carat weight princess shape diamond depends on other factors such as cut, but is usually in the ballpark of around 6.9 mm along one square edge. While this picture will give you an approximate idea of how big a diamond will appear viewed on the hand, remember that the size of the ring you choose or need could be quite different in size to that shown in this image.

Photos can sometimes be notoriously deceptive - I've tried to make this one as clear as possible, but remember seeing the stone in person will give you a very different judgement of size to viewing it on the internet. Long slender fingers will change how a diamond looks as much as the diamond's carat weight - so look beyond just considering the 1.57 carat weight of this princess stone.
