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).

Make sure to cast a glance over neighbouring carat sizes around the 1.70 carat size this diamond has, because in doing so your choices regarding other diamond properties can open up. This G color diamond is a whiter stone than the bottom normal color ratings of J and below; it's a a balance-point between quality and budget, allowing you to get more in the other Cs of diamonds for example cut rating. The SI clarity group of diamonds (which this SI1 clarity diamond is part of) is the happy hunting ground for diamond bargain hunters. Look for a diamond that appears "clean" to the naked eye, either by going over the diamond in the flesh, or by checking out an online enlarged photo of the diamond.

Girdle thickness (for this diamond the girdle is "Slightly thick to thick, faceted") can have an important role in the apparent size of the diamond, as is explained in my article about girdle thickness.

The visual appearance of this diamond will be quite good because of its Premium cut, although inferior to the more expensive higher cut grades. In analyzing the $14330 price for this diamond, put in some thought into whether you need all the properties to be as good as they are.
