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 on Hand of a 1.68 Carat Diamond

This 1.68 diamond will appear about the size shown in the picture, for an average-sized woman's hand. An average round stone with a 1.68 carat weight has a diameter of 7.8 mm, although this can change depending on the cut. The ring shown in the image is an average-sized size six ring, but bear in mind the ring you get could be significantly larger or smaller. Be careful of reading too much into just a picture - it can't be completely representative of all finger and hand types - you are best advised to get a bit of an idea in store with an actual ring. Also take into account the width and overall length of your fingers.
