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 is a potential great bargain, providing it is eye clean. Try examining the high resolution photo closely to work out if the diamond presents well from on top, which;this is where it will mostly be seen from. Most consumers won't notice the color in this G color diamond, unless the stone is compared side by side with a diamond with say a D color rating (for multistone rings this is important). For $42860, if you've done your shopping properly you should have a nice stone, so make sure you're plenty critical as you look at this diamond. By lowering the carat size of this stone (3.00 carats), it's possible you might save a few dollars that can go towards other costs.

The Girdle Thickness for this diamond is "Slightly thick" - you can consult my piece on girdle thickness if you are interested in finding out more about how girdle thickness can play an important role.

Since this diamond is a Premium cut diamond, it offers fantastic value for your dollar, since it doesn't attract the price premium of the higher cut gradings, despite still providing decent optical performance.
