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).

A 0.93 Carat G Color SI1 Clarity Ideal Cut Round Cut Diamond for Purchase

One option with SI1 clarity diamonds is to ask a James Allen member of staff to check the diamond themselves to see whether it is eye-clean, that is after you've already assessed the photo yourself, so you're not wasting time on no-hopers.

This diamond's Ideal cut rating indicates it has excellent proportions and very good or better symmetry and polish ratings.

The G color of this diamond provides value for your dollar, since it isn't a member of the expensive premium color grades D-F. Take note of this diamond's girdle description - "Medium to slightly thick" - if you're unsure about girdles, go have a read of my girdle thickness article. This diamond's $4070 price is a substantial investment for most people, but the tradeoff is a nicer and bigger stone than if you were to only spend a few hundred bucks. The SI clarity range (which this SI1 clarity diamond is part of) is the happy hunting ground for diamond bargain hunters. Look for a diamond that appears "clean" to the naked eye, either by going over the diamond in the flesh, or by checking out an online high resolution photo showing the stone.
