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).

The chance in color between any neighbouring colors in the D-E-F color range is only detectable in a lab, meaning this F color diamond is not distinguishable from diamonds rated one color either side of it. The visual appearance of this diamond will be quite good because of its Premium cut, although inferior to the more costly higher-rated cut grades. SI stands for Slightly Included, which means this SI1 stone has inclusions which are definitely visible at 10 x magnification and possibly to the naked eye, but which provide the opportunity for significant price discounts if they are not. This diamond's pricetag of $500 means it is firmly a member of the cheapest group of diamonds which might be used in an engagement ring setting. Think about whether you are really set on the 0.30 carat weight of this diamond - or whether you are able to extend a bit more to buy a slightly larger diamond.

This diamond's girdle is "Medium", which plays a impact on the size and sparkle of a diamond, as explained in my diamond girdle page.
