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).

This diamond's ticket price of $1580 means it is firmly a member of the cheapest group of diamonds that are considered for an engagement ring setting. Several diamond sellers 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 general shape. An untrained eye won't notice the color in this G color diamond, unless the stone is compared side by side with a higher color grade diamond (something to think about if you're going for a 3 stone ring).

If you're looking at this diamond and thinking to yourself that you want to improve other characteristics of the diamond which don't affect size, think about downgrading the 0.64 carat size of this diamond. If you're unsure from the photo of this SI1 clarity diamond whether it is eye-clean, try contacting a James Allen sales rep and asking them to personally analyse the diamond and get back to you - they will give you an honest answer.
