•    Knot crystals which reach the surface of the diamonds and resemble a knot in the wood.

In rare cases, these may help diamonds look more attractive when they are shaped like a heart, dolphin, or any fancy shape. When they appear as colored, they are considered as an additional crystal seated inside the diamond.

Twinning wisps are referred to the strings of small clouds or pinpoints. These could also be crystals which formed as a result of an uneven crystal structure. Grain lines and grain line groupings are usually colorless and nearly impossible to detect. Such imperfections may have resulted from a natural disruption from thousands of years ago.

Indented Naturals
