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).

SI is short for for Slightly Included, which means that this SI1 stone has inclusions that are certainly visible at 10 x magnification and may often be visible to the naked eye, but which offer the opportunity for significant price discounts if they're not. Place this 1.02 carat weight in perspective as you weigh up your purchasing choices - there are going to be other diamonds of about the same size which could offer more in terms of their cost and properties. According to James Allen, the Hearts & Arrows cut is the "ultimate expression of love". Whether that's true or not, what choosing a diamond with this cut does suggest is that you are serious about obtaining the best possible visual performance from the diamond. A G color diamond such as this one is a good option balancing white pureness and money considerations. If you have got some money but do not want to waste it, this is a sensible color range to do your searching within. Don't neglect diamond characteristics outside the four Cs, for example girdle thickness - which can be important for reasons discussed in the article on girdles on this website.

Weighing up the $6370 price for this diamond, make sure you consider whether any of the property qualities are excessive for your needs.
