Very Slightly Included (VS1 and VS2)
Inclusions are so small and observed with effort under 10x magnification, but can be characterized as minor, considered "eye clean"

Slightly Included (SI1 and SI2)
Inclusions are noticeable under 10x magnification

Included (I1, I2, and I3)
Inclusions are obvious under 10x magnification which may affect transparency and brilliance

Sofia Kaman Fine Jewels

The diamond making process is a complex one. As carbon is heated and pressurized, natural organic material can get caught up in the process creating markings visible to the eye called inclusions. In the 4Cs of diamonds, the clarity scale is based off of the visibility of inclusions, and blemishes (which lie on the surface of a stone) under 10x magnification. The scale begins at Flawless (FL), then Internally Flawless (IF), Very, Very Slightly Included (VVS1, VVS2), Slightly Included (SI1, SI2), and Included (I1, I2, I3.) In general, the fewer inclusions a diamond has, the higher the value. Here you can also play with the scale. Looking at stones and the placement of inclusions is very important. A stone may have been graded as an SI2 stone, but depending on the placement of the marking, the inclusions may not be very visible or could be covered with a strategic prong setting.

Again, here are Sofia Kaman we embrace the underdog and love the unique look of a Salt and Pepper diamond (a stone that has many visible inclusions giving it a peppery, speckled look.) No two stones are alike, and we adore their galactic, mesmerizing appearance. Shop our Salt and Pepper Diamonds!
