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).

If you are looking at this diamond and thinking to yourself that you want to improve other characteristics of the diamond not related to size, think about downgrading the 1.02 carat weight for this diamond to achieve that end. In analyzing the $5700 price for this diamond, put in some thought into whether any of the property qualities are excessive for your needs. 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. If you are unsure from the photo of the SI1 clarity diamond on this page whether the diamond is eye-clean, you can ask a James Allen sales rep and asking them to personally analyse the diamond for you - they will give you an honest response.

Pay attention to this diamond's girdle characteristic - "Medium to slightly thick, faceted" - and if you don't know about girdle thickness, go have a read of my girdle thickness article. Many different companies will provide an Ideal cut diamond cut grading, and these diamonds are usually (as is the case here) perfect with respect to proportions and the general shape.
