VVS1. VVS2. VS1. VS2. SI1. The grading terminology sounds precise until you realize most buyers can't tell the difference between them without a 10x loupe. Here's what these grades actually mean — and which one you should buy.

What Clarity Grades Actually Measure

Clarity grades measure the presence of inclusions and blemishes in a diamond. The critical fact most salespeople gloss over: all grades from FL through VS2 are "eye-clean." You cannot see the inclusions with the naked eye. The difference exists under magnification only.

VVS — Very Very Slightly Included

VVS diamonds have inclusions that are extremely difficult to see even under 10x magnification. To the naked eye: completely clean. To everyone who sees your ring: indistinguishable from a Flawless stone.

Who should buy VVS: People who want the best documentation of quality, collectors, or buyers who will feel better knowing the stone is near-perfect under magnification.

VS — Very Slightly Included

VS diamonds have inclusions that are minor and difficult to see under 10x magnification. Both VS1 and VS2 are universally eye-clean.

Who should buy VS: Most buyers. This is the sweet spot for value — you get an eye-clean stone with a certified high clarity grade, at significantly less than VVS prices.

The VVS vs VS Price Difference

On a 1-carat round brilliant, expect to pay 15–25% more for VVS2 over VS1, with comparable cut and color. That premium buys you documentation, not appearance.

Cut Outranks Clarity Every Time

A VS1 stone with an Excellent cut will outshine a VVS1 stone with a Good cut in every lighting condition. If you're choosing between upgrading clarity and upgrading cut, upgrade cut.

What I Recommend

For most buyers, VS1 or VS2 is the rational choice. Eye-clean, certified, and priced sanely.
