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).

0.51 Carat G Color SI1 Clarity Hearts & Arrows Ideal Cut Round Cut Diamond -

This diamond has an interesting coupling of a quite good color rating of G, coupled with an occasionally shaky SI1 clarity rating - this means you need to check the clarity yourself in the photo.

If you're a little hesitant from the photo of this SI1 clarity diamond whether it is eye-clean, you can ask a James Allen representative and requesting them to personally assess the diamond and get back to you - they will give you an honest answer. The Hearts & Arrows cut of this stone places it in the upper 1% of diamonds on the marketplace today in terms of cut quality. This cut is the top cut offered by James Allen and ensures the highest diamond sparkle. Think about whether you're really set on the 0.51 carat weight of this diamond - perhaps you can extend a bit more to get a slightly larger rock. The G color of this diamond provides great value, as it isn't one of the expensive premium color grades D-F. Spending only $1220 on the diamond, one will be able to save more money to put towards other costs, for example a wedding reception.

Girdle thickness (for this diamond the girdle is "Thin to slightly thick") can have an important role in the size presented by the diamond, which is detailed in my girdle thickness article.
