VS1 clarity refers to a specific clarity grade assigned to lab grown diamonds. Clarity is one of the four Cs (Cut, Color, Clarity, Carat weight) used to assess the quality and value of a lab grown diamond. VS1 stands for "Very Slightly Included 1," which means that there are very minor inclusions visible under 10x magnification. These inclusions are typically not visible to the naked eye.

VS1 clarity lab grown diamonds offer a high level of clarity and are considered to be of excellent quality. The inclusions present in a VS1 lab grown diamond are very small, scattered, and do not significantly impact the overall beauty and brilliance of the lab grown diamond. This clarity grade allows for a visually clean and stunning appearance to the naked eye.

However, it's important to note that the specific location, type, and size of the inclusions within a VS1 clarity lab grown diamond can still vary. It's recommended to view the lab grown diamond in person or review detailed images to assess its appearance and visual impact. Additionally, other factors such as the cut, color, and carat weight of the lab grown diamond should also be considered when evaluating its overall quality and value.
