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).
2.66 Carat Diamonds
A diamond which has a size of 2.66 carats is the same as a 266 point diamond. Although there is a strong correlation between the carat weight of a diamond and its width, this does not guarantee that every 2.66 carat diamond is 9.08 mm wide.

A way of using numbers to help you compare diamonds is to calculate the cost per carat of diamond. Is a handy hint - as well as searching for 2.66 diamonds, try starting your search by examining another property of the diamond, for instance the name of an online jewellery store you would be happy to buy a diamond from.
Although it is not a problem for most people, it is possible for a diamond to be too large. This is much more likely to happen with women who have particularly petite hands.
Ever looked at a similar carat size of diamond and another gemstone and wondered why the stones appeared so different in size? This is undoubtedly because different types of stones have different specific gravity densities, leading to this discrepancy in size. 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.
In terms of diamond properties, the carat weight of the diamond should be considered alongside the many other characteristics of the diamond, in order to find a diamond which is balanced and hence not let down by being of poor quality in one of these departments.
