What Are Inclusions?
The internal irregularities in a diamond are the diamonds' inclusions. Inclusions typically consist of crystals, clouds and feathers. Crystals are tiny minerals that become trapped inside a diamond during its formation.
SI 2 - The inclusions in these stones are easily seen with a 10X loupe;
without a loupe, they are "eye - clean" when viewed from the top of the stone.
Naturally, inclusions that don't impede the light's passage through the diamond or visibly decrease its beauty will not have a substantial effect on its value.
Very small inclusions in a diamond.

Quartz with inclusions. The inclusions are the mineral clichlore, a form of chlorite. It's believed to have an overall healing and stabilizing effect. When included in quartz it helps to stabilize the high vibration of the crystal.
Internally, inclusions may occur in the form of tiny spots, fractures, feathers etc., while externally they may appear as scratches and fissures. Sometimes an inclusion does not affect a diamond's brilliance or gets easily hidden by its setting.
