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).

Several companies will offer an Ideal cut diamond cut grading, and these diamonds are usually (as is the situation here) perfect with respect to proportions and the overall shape. Think about whether you are entirely set on the 0.61 carat weight that this diamond is - perhaps you can stretch to get a bigger rock. For a diamond, a cost of $1560 really places it in the lowest price group of diamonds, even more so for engagement rings.

This SI1 clarity stone is a potential great bargain, with the proviso it is eye clean. Try examining the high resolution photo in detail to check if the diamond presents well from on top, which;this is where the diamond will primarly be viewed from.

Take note of this diamond's girdle characteristic - "Thin to medium" - and if you don't know about girdle thickness, try reading my short explanation of girdle thicknesses. The G color of this diamond offers value for your dollar, as it isn't a member of the expensive premium color grades D-F.
