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 "Medium, faceted", which plays a role in the size and sparkle of a diamond, as written about in my diamond girdle article. The Ideal cut means the diamond will shine significantly more in comparison to lower quality cut diamonds, maximizing attractiveness.

Usually VS1 clarity diamonds are the best value "safe" clarity grading in terms of purchasing online without a photo - although a lower clarity grading is possible you need to see a high quality photo showing the diamond to assess the inclusions for yourself. The chance in color between any neighbouring colors in the D-E-F range can only be detected in a specialist laboratory environment, with the significance that this F color diamond is indistinguishable when compared with diamonds rated one color either side of it. Remember to have a look at nearby carat sizes around the 1.27 carat weight this diamond has, because in doing so your choices regarding other diamond properties may become available.

For $13290, you should be getting a nice stone, so make sure you're harsh in your judgement as you look at this stone.
