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).

To get some additional pointers on the "Medium to slightly thick" girdle of this diamond, have a read of the article about girdles. If you can see the diamond in person or see zoomed in photos of the diamond (like the one for this SI1 clarity diamond), this is where the most valuable deals are to be found - identifying an SI1 or SI2 stone which is "eye clean" is a satisfying experience that translates to less dollars spent. Spending $33060 towards a stone nets you a diamond well above the cut, such as this diamond. Just be sure that you and your partner are happy spending the money. This G color diamond is less colored than the lowest normal color gradings of J and below, which means it's a great compromise between money considerations and quality, allowing one to get more in the other Cs of diamonds such as carat size. Although not quite as perfect a cut as Hearts & Arrows, the Ideal cut of this diamond means it is significantly cheaper, because you're not forking out money for a "perfectly" cut diamond.

Place this 2.73 carat weight in the right reference frame as you consider your buying choices - there are going to be other stones of about the same size that could provide more in terms of their price and properties.
