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).
1.95 Carat Diamonds
A diamond with a size of 1.95 carats weighs in normal everyday weight units exactly 390 mg. In looking at the 8.18 mm width of a 1.95 carat diamond, remember that this width can vary quite a bit depending on the depth of the diamond.

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. For prospective buyers who are really focused on the size of a stone but not the material or quality, consider changing to a different gemstone apart from diamond. Some other gemstones are significantly less dense than diamond, which means for a certain carat weight they will have a larger volume and hence will look bigger to the naked eye.

It can be humbling to compare the 1.95 carat weight with famous diamonds such as the akbar shah diamond, which came in at a final cut carat weight of 72 carats. Five small diamonds that add up to one carat are generally not as valuable as a single diamond that weighs one carat, so be short not to compare a single diamond of carat weight 1.95 with a ring which has a total diamond weight of 1.95.
People say the four cs for a reason - diamond carat size is just one of the four cs and the others are arguably just as important in determining how 'attractive' and 'good' a diamond is.
