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).
0.07 Carat Actual Size (Princess Shape)
This article includes a useful photo showing you the apparent size of a 0.07 carat size princess shape stone, when viewed in place on the hand of a woman. If you have got a ring in your possession and you know what it's size is, you can compare it to the US size six ring shown in the image on this page - this will help you get a concrete idea of the diamond size in the picture. Photos can sometimes be notoriously deceptive - this one is pretty clear cut, but don't forget viewing the diamond in person may give you a totally different impression of size to examining it on the internet.
