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).
1.48 Carat Diamonds
Girdle thickness is a diamond property which many people never even think about, but which can critically affect how big the diamond appears to be. Diamond size means both the carat weight of the diamond and the width of the diamond, and the width of the diamond increases at a much slower rate compared to the carat weight of the diamond.

Diamonds with a size of 1.48 carats are aplenty, but diamonds with a size of 1.48 carats and all the other desirable properties of the diamond are not so common - so don't forget to think about these other properties.
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. Although it is of limited usefulness, a lot of people wonder what the average size of a diamond is (about one third of a carat) when they are searching for a diamond themselves.
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.
