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).
0.70 Carat Diamond Actual Size
This 0.70 diamond will look about the size shown in the illustration, on a typical woman's hand. The woman's hand shown in the picture has long and thin fingers - which may not be what yours look like - if they're not, bear in mind that a diamond engagement ring may look quite different when worn. Try and avoid making the mistake I made of examing a potential diamond engagement ring placed on my own, male finger - remember it's going to go on a usually smaller and more petite female hand, where it will likely not shrink quite as much as when placed on a male hand.
