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).
2.68 Carat Diamonds
Each carat in a diamond is equivalent to 200 mg, so this 2.68 carat diamond weighs 536 mg. The shallowness of a diamond, which depends on how the diamond has been cut, will affect the relationship between carat weight and diameter of the diamond - because of this reason, 2.68 carat diamonds will only average a width of 9.10 mm, but will not always be precisely this width.

Some unethical store assistants will talk about average diamond size in trying to pressure couples into buying a diamond ring more expensive than they can afford - even though the average is around half carat, you should be buying a diamond based on what you can afford, and what you as a couple would feel comfortable buying. A large diamond which has a huge crack down the middle, or alternatively a big yucky looking inclusion, is not a good look - it looks like someone has gone for size and sacrificed all the other desirable properties of the diamond. Clarity, for example, can be just as important in picking a diamond.
