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 Sizes of a 0.10 Carat Princess Shape Diamond

Carat weight doesn't always mean much until you see it in context - this article provides a human hand as "context" to simulate the apparent size of a 0.10 carat weight diamond of princess shape. Photos can sometimes be a little dependent on the viewer - I've tried to make this one as clear as possible, but remember viewing the stone in the flesh may give you a totally different impression of size to examining it on the internet.
