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).
1.70 Carat Diamond Actual Size
A typical round stone with a 1.70 carat size has a width of 7.8 mm; bear in mind that this can vary slightly depending on the cut. The picture shows a ring which is US size 6; this is the same as an L 1/2 size in places such as Australia and Britain, and is an average ring size. The woman's hand pictured has long and thin fingers - your fingers may or may not be similar - if your fingers are differently shaped, bear in mind that the ring you buy may look quite different when worn. Do not forget to take into account not just the size of your hand as a whole, but in addition whether you have long and thin digits or squatter ones. If you have been stressing about how expensive diamonds are but are still really set on getting one, here's something to cheer you up - the diamonds often appear bigger when put on a woman's hand, especially in cases where her hand is small and petite.
