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 1.50 Carat Diamond Size on Hand

This 1.50 diamond will appear about the size shown in the illustration, on a typical woman's fingers. A person's fingers could be quite a bit thicker or thinner than the ones shown in the picture, which are quite thin - keep in mind yours probably look quite different.

The ratio of your ring finger's length and its width can play a pivotal role in how the diamond looks, which you should take into consideration. Don't make the mistake I made of examing a potential diamond engagement ring placed on my own, male finger - remember that it is ending up on a generally smaller and more delicate female hand, which will make the diamond appear significantly larger.
