What is a VS1 Diamond?

by Willyou.net * Jul 4, 2021

VS1 diamonds are diamonds with a clarity grading of Very Small Inclusions. This means that the diamond includes inclusions. But most of the inclusions are barely noticeable to the naked eye.

What is VS1 Clarity?

Diamonds with a VS1 clarity grading have inclusions that are barely visible under 10x magnification. And even with magnification, it can take several seconds until the blemish spot is located. Inclusions with a VS1 grading are hardly noticeable to the naked eye, especially in diamonds that are less than 2.0 carats. A VS1 diamond is one of the most affordable diamonds without any visible inclusions.

Diamond Clarity

To understand what a VS1 diamond grading is, it’s important to first understand the most reputable scale used for evaluating a diamond’s clarity – the GIA grading scale. 

Diamonds are graded on their 4 C’s: color, cut, carat, and clarity on the GIA scale. The clarity of a diamond is graded on its visual appearance and how many inclusions or blemishes it has. A diamond’s clarity can affect its value and overall price and is graded on a scale from Internally Flawless (IF) to Inclusions 2 (I2). Eye clean diamonds are included within the clarity spectrum and can be found in various grades, such as Si1 or Vs2 diamonds. 

The diamond clarity scale for GIA contains the following grades, with VS1 located between VVS2 and VS2:

Internally Flawless (IF), Very Very Small Inclusions 1 (VVS1), Very Very Small Inclusions 2 (VVS2), Very Small Inclusions 1 (VS1), Very Small Inclusions 2 (VS2), Small Inclusions 1 (SI1), Small Inclusions 2 (SI2), Inclusions 1 (I1), Inclusions 2 (I2).

VS1 Diamond Price

A VS1 diamond will typically cost more than a VS2 diamond – about 10% more. The higher the clarity grade, the more expensive the diamond will be. Buying a diamond with a VS1 clarity grade will provide the same beauty as a diamond with VVS2 clarity, but will cost between 15-20% more.

VS1 Diamonds versus VVS Diamonds

The main difference between a VS1 diamond and a VVS diamond is its price. VS1 diamonds are less expensive than VVS diamonds. Both diamonds are eye-clean, but the inclusions on a VVS diamond are harder to see than on a VS1 diamond. Although both require magnification to see the inclusions. So if you are more concerned with price, the VS1 diamond is the best choice. And if clarity is more important, then a VVS diamond is the better choice.
