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 SI1 clarity stone represents potential great value, with the proviso it is eye clean. You can go over the high resolution photo closely to check if the diamond looks good from on top, which;this is where it will mostly be seen from. Girdle thickness (for this diamond the girdle is "Thin to medium") can play an significant role in the size presented by the diamond, which is detailed in my article about girdle thickness. If you're looking at this diamond and considering whether to improve other characteristics of the diamond not related to size, think about downgrading the 0.63 carat weight of this diamond. An untrained eye won't notice the color in this G color diamond, except if the stone is held up against a higher color grade diamond (something to think about if you're going for a 3 stone ring). Several diamond sellers will provide an Ideal cut diamond cut grading, and these diamonds are almost always (as is the case here) perfect with respect to proportions and the general shape.

This diamond's ticket price of $1570 puts it firmly in the least expensive group of diamonds that are considered for an engagement ring setting.
