Slightly Included Diamonds

Inclusions are a diamond clarity term that refers to internal imperfections or natural characteristics in a diamond. No two diamonds are alike and most feature some level of surface blemishes or internal inclusions. Only IF and F clarity diamonds are considered truly "flawless."

A slightly included (SI) diamond features inclusions visible under 10x magnification. The 360-degree views we offer are provided at 20x magnification, which is twice the magnification of a jeweler's loupe. Under this magnification, you may notice a slight inclusion with even an IF clarity that would be imperceptible otherwise.

An SI1 clarity grade is often considered eye-clean, which means it's difficult to see any blemishes without magnification. SI2 diamonds are a slightly less expensive grade, sometimes featuring inclusions that can be seen with the eye from certain angles. The shape of the diamond helps conceal inclusions as well. Round cuts can hide blemishes that would be visible in an emerald or Asscher shape.

There are five key factors that determine a diamond's clarity grade, including the size, number, position, nature, and color or relief of the characteristics.
