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).

1.37 Carat Diamond Size on Hand

This 1.37 diamond will appear about the size shown in the picture, on a typical woman's finger. You can use the 7.3 mm average diameter for this 1.37 carat diamond by measuring the length and width of your own finger in order to get an appreciation of what a diamond of this size will look like on your finger. This illustration displays a size L 1/2 ring (British and Australia), which is the same as a US size six . The hand of the woman shown in the picture has quite long and slender fingers - which may not be what yours look like - if your fingers are differently shaped, be aware that a diamond engagement ring may present quite differently on your finger.

The ratio of the length of your ring finger and its width can play a pivotal role in how the diamond looks, which you should take into consideration.

The apparent size of a diamond depends heavily on what it is shown against - the hand - a petite hand will cause the diamond to appear significantly larger, with the reverse applying as well.
