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 has a girdle described as "Thin to medium", which plays a role in the size and sparkle of the diamond, as explained in my diamond girdle page. Most consumers won't notice the color in this G color diamond, unless the stone is compared side by side with a higher color grade diamond (for multistone rings this is important). The Ideal cut ensures the diamond will shine significantly more in comparison to lower quality cut diamonds, maximizing attractiveness. Despite the fact this VS1 clarity diamond is pretty much guaranteed to be "eye-clean", if you're aiming to reduce expenditure, try checking out SI clarity diamonds. You can manually pick a diamond that is eye-clean in a photo or when viewed in person.

Weighing up the $16500 cost of this diamond, put in some thought into whether you need all the properties to be as good as they are. If you are looking at this diamond and thinking to yourself that you want to improve another property of the diamond not related to size, think about downgrading the 1.60 carat weight of this diamond.
