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).

Take note of this diamond's girdle description - "Thin to slightly thick" - and if you don't know about girdle thickness, try reading my short explanation of girdle thicknesses. Spending $6290 towards a stone nets you a diamond well above the cut, like this one. A tip: sanity check that you're happy spending the money. A G color diamond like this one is a good option balancing white pureness and money considerations. If you've got some dollars to spend but don't wish to splurge unnecessarily, this is a great color range to do your searching within.

SI is short for for Slightly Included, which means this SI1 stone has inclusions that are certainly visible at 10 x magnification and possibly to the naked eye, but which provide the potential for bargains if they are not.

With regards to cut alone, a Hearts and Arrows cut diamond gets you as close to a perfect diamond as you can get. This very rare of diamond cuts is offered to a buyer who has a special interest in maximizing the cut of the diamond, and as a result the appearance of the diamond resulting from its superior light catching qualities. If you're looking at this diamond and thinking to yourself that you want to improve another property of the diamond not related to size, think about downgrading the 1.07 carat weight of this diamond.
