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).

Seeking a 0.91 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 step up in clarity grading comes from there being smaller or less inclusions, or when the location of the inclusion is more favourable to the appearance of the diamond (for example if it is hidden from sight).

Girdle thickness (for this diamond the girdle is "Medium to thick, faceted") can have an important role in the size presented by the diamond, as is explained in my girdle thickness article. F color diamonds are pretty much colorless, meaning they are included in the pure white diamond range. If your goal in buying a diamond is to get the biggest rock for your money, then you may have to reduce any requirements on other characteristics of the diamond, such as cut. This Good cut diamond will be much cheaper than higher grade cuts, although at the cost of somewhat inferior visual appearance properties.

If you are a cautious online purchaser, then this VS1 clarity diamond is relatively safe bet, since it is unlikely to have any inclusions that can be seen by the naked eye. Place this 0.91 carat weight in perspective when you weigh up your diamond options - there are going to be other stones in the same size range which could provide more with regards to their price and characteristics.

For $5070, if you've done your shopping properly you should have a nice stone, so make sure you're plenty critical when you're looking at this stone.
