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).

Pick for This Morning 3.50 Carat F Color VS1 Clarity Premium Cut Round Cut Diamond

This VS1 clarity diamond is a slight improvement over a VS2 clarity diamond, the step up in clarity grading comes from there being smaller or less inclusions, or because the location of the inclusion is more favourable to the appearance of the diamond (for example if it is hidden from sight).

If you're a cautious online purchaser, this VS1 clarity diamond is relatively safe bet, because the chances are low of it having any inclusions that are visible to the naked eye. The size of this stone is 3.50 carats - but make sure you check out the other diamonds for sale with that same 3.50 weight which may have a more desirable combination of properties and price.

Girdle thickness (for this diamond the girdle is "Thin to slightly thick, faceted") can play an significant role in the size presented by the diamond, which is detailed in my article about girdle thickness. F color diamonds are very colorless, meaning they are part of the pure white group of diamonds. Throwing $97600 towards a stone gets you a diamond well above the cut, such as this diamond. Just be sure that you and your partner are happy spending this amount of money on a diamond. Because this diamond is a Premium cut diamond, it offers fantastic value for your dollar, since it doesn't attract the price tag added to the higher cut gradings, despite still providing reasonable optical performance.
