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).

For any diamond, a price of $1050 really places it amongst the cheapest set of diamonds, especially for engagement rings. The visual attractiveness of this diamond will be quite good because of its Premium cut, although not quite as good as the more costly higher-rated cut grades. The listing for this diamond doesn't have anything for girdle property - if you'd like to know more try asking a sales rep to clarity. An untrained eye won't notice the color in this G color diamond, unless the stone is held up against a higher color grade diamond (for multistone rings this is important).

SI is short for for Slightly Included; that means that this SI1 stone has inclusions that are certainly visible at a zoom level of ten times and may often be visible to the naked eye, but which offer the potential for bargains if they are not. The carat weight of this diamond is 0.53 carats - be sure to check out the other diamonds for sale with a similar 0.53 weight which might have a more desirable combination of properties and price.
