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).

Found: this 0.38 Carat F Color VS1 Clarity Good Cut Round Cut Diamond

This VS1 clarity diamond offers a bit of an improvement in clarity over a VS2 clarity diamond - the higher rating is given when there are fewer or smaller inclusions, or when the location of the inclusion is more favourable to the appearance of the diamond (hidden).

Consider if you're really set on the 0.38 carat weight that this diamond is - or whether you can stretch to get a bigger rock. The Girdle Thickness for this stone is "Medium to slightly thick" - I suggest consulting my piece on girdle thickness if you are interested in finding out more about how girdle thickness can play an important role.

To the naked eye, this F color diamond by itself appears completely white and pure - there isn't a method to detect any color in the diamond utilizing just the human eye and no other nearby diamonds, or to identify the differences between it and others within the colorless range.

This diamond's ticket price of $650 puts it firmly a member of the cheapest group of diamonds that might be used in an engagement ring setting.

VS is an abbreviation for Very Slightly Included - this VS1 clarity diamond has some minor inclusions that may or may not be visible at 10x magnification, but are almost never visible with the naked eye - but it can occur occasionally. If your goal in buying a diamond is to get the biggest diamond possible, then you may have to reduce any requirements on other properties of the diamond, for example cut. This Good cut diamond will be much cheaper than higher grade cuts, because it has decreased optical appearance.
