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).

You couldn't be more wrong - the golden jubilee diamond is an example of how big diamonds can really be - it is 545 carats, or a weight of more than 100 g, which is about a quarter of the weight of a can of coke.
Don't forget to think about other diamond characteristics such as diamond cut, which plays a critical role in determining the amount of light that gets into the diamond and the degree to which the diamond sparkles in light.
