Pinpoints (Pp) Inclusion Photography
Internal Pinpoints (Pp), or Pinpoint Inclusions are minute included crystals within the diamond that appear white under magnification. Large groupings of small pinpoints can create a cloud inclusion effect.
Pinpoints: Miniscule spots internal to a Diamond. A cluster of pinpoints can form a cloud.
Tone: A color's position on a colorless-to-black scale.

Pinpoints: areas of minute, dot-like inclusions.
Twinning Wisps: cloudy areas produced by distorted crystal growth.
Pinpoints
One of the most common inclusions, a pinpoint is a white spot that occurs within the diamond during its formation. These are tiny crystalline growths.

Dispersion, refers to an optical property of gemstones whereby flashes and pinpoints of spectral colors are displayed as the stone is turned in the light.
Cloud: Several pinpoints lying together across various planes.
Feather: a break in a gemstone that extends from the surface to the interior, often white and feathery in appearance.
"In this well-organized and deeply researched study, McRaven pinpoints six essential principles of 'spec ops' success: simplicity, security, repetition, surprise, speed, and purpose."--Publishers Weekly.
It pinpoints the discovery to a tunnel on Anthony's Nose, of which there are four. It also gives the discoverer and his position which explains how the specimens were encountered.
Pinpoint: An inclusion within a diamond. A gathering of pinpoints is called a "cluster" or "cloud." A cloud or cluster can appear as a hazy area in the diamond, a pinpoint appears as a dot.
Cloud: A cloud is a type of inclusion that is caused by a group of very small pinpoints that are tightly packed together inside of the diamond. They will typically resemble a cloud, hence the name.
Additionally, small pinpoints or feathers do not usually affect fancy colors due to the deeper coloring of the diamond. Fancy diamonds of VS or better clarity are more uncommon in nature and therefore command a greater price.
A small area of intense crystal structure distortion which usually associated with pinpoints.
Graining
Usually graining refers to internal irregular crystal growth which may appear milky like faint lines or streaks.

INCLUSION - Internal characteristics present in gemstones. Common diamond inclusions include feathers, crystals, fractures, graining, pinpoints, and cavities.
Any of several types of clarity features which are enclosed within a host diamond and they may reach the surface. Some examples are knots, feathers, crystals, needles, clouds and pinpoints.
Knot ...
An internal imperfection or characteristic which reduces the clarity or brilliance of a gemstone. Common gemstone inclusions are feathers, crystals, fractures, needles, graining, pinpoints and cavities.

These types of inclusions are not mentioned in the grading report as they are very tiny and difficult to find. They are mentioned as 'pinpoints not shown or shown' in the comments of the grading report.
