VVS stands for Very Very Slightly Included — graded under 10x magnification in a controlled laboratory setting. But what does a VVS inclusion actually look like under a loupe? And what does this grade mean for a diamond you will wear on your finger?

The 10x Standard

Every GIA and IGI clarity grade is determined at 10x magnification. Inclusions visible only above 10x are not graded. Inclusions requiring less than 10x to see push the stone into SI or Included territory. The 10x standard has been used since the GIA introduced clarity grading in 1953.

What VVS Looks Like Under the Loupe

A VVS1 diamond has inclusions that are extremely difficult to find even for a trained grader at 10x. VVS1 inclusions are visible only from the pavilion (bottom) face — flip it face down under the loupe and search carefully. Common VVS1 inclusions include: pinpoints, needles, growth lines (in CVD diamonds), and extremely diffuse clouds.

The Naked-Eye Reality

This is the fact the clarity grading system obscures: everything from Flawless down through VS2 is completely invisible to the naked eye in any real-world condition — daylight, indoor lighting, on a ring or in earrings. The 10x grade is documentation of what exists at laboratory magnification. It is not a proxy for visual quality in normal wear.

Why VVS Commands a Premium

Documentation value: The certificate states VVS. Sourcing precision: Specifying VVS1 at the crystal stage means the producer selected for quality at the growth phase. At StudsDirect, our SEEPZ sourcing network lets us specify VVS1 at the crystal stage rather than buying grade-lottery at the commodity level.

Every stone we sell is VVS1 and IGI certified. See the full collection — or continue with our guides on IGI vs GIA grading and the complete VVS vs VS clarity comparison.
