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).

The SI clarity range (which this SI1 clarity diamond is part of) is the happy hunting ground for diamond bargain hunters. Look for a diamond that is "clean" to the naked eye, either by examining the diamond in person, or by checking out an online high resolution photo showing the stone. For any diamond, a price of $1190 puts it amongst the lowest price group of diamonds, even more so for engagement rings. The G color of this diamond offers value for your dollar, as it is not a member of the expensive premium color grades D-F.

If you are checking out this diamond and thinking to yourself that you want to improve another property of the diamond which don't affect size, you may wish to reduce the 0.54 carat size for this diamond to achieve that end. Many different companies will provide an Ideal cut diamond cut grading, and these diamonds are almost always (as is the situation here) perfect with respect to proportions and the general shape. Take note of this diamond's girdle description - "Medium to slightly thick" - and if you don't know about girdle thickness, try reading my girdle thickness article.
