Diamonds are brought to the surface in two main magma types with fairly extreme compositions. These are:
Kimberlites and Lamproites.
You can read more about them, below.
Volcanic pipes that blast diamonds to the earth's surface, also erupt garnet xenoliths onto earth's surface. Only about one in every 200 such pipes contain diamonds.

Silica is the most abundant component in magma and has the greatest effect on its characteristics. The amount of silica present determines the magma's viscosity, which in turn influences the explosiveness of volcanic eruptions.
Composite volcanoes can contain virtually any kind of magma ranging from basaltic to rhyolitic. Andesitic magma is the most common. One stratovolcano contains unique carbonatite magma, which is unlike the magma of any other volcano in the world.
Canary diamonds are a type of yellow diamonds known for their intense yellow hue. They are considered one of the most valuable and sought-after fancy colored diamonds due to their rarity in nature and vibrant color. Canary diamonds are typically graded based on the intensity of their yellow color.
Kimberlite pipes form when magma rises from deep within the Earth's mantle and rapidly reaches the surface, carrying diamonds and other minerals with it. The extreme pressure and temperature inside the mantle crystalize carbon atoms into diamonds within the kimberlite magma. When the kimberlite erupts onto the surface, it brings diamonds along, creating diamond deposits.

Debeers diamonds are the standard by which most diamonds are measured.
The most common use of diamonds is for industrial tools, because industrial diamonds are the most common diamonds.
Yes, diamonds can be naturally red. In fact, these are the most rare of natural diamonds.
Most jewelery stores in most cities in Europe sell diamonds.
Diamonds are cut in the Netherlands, in India, in Canada and Australia. India may cut the most diamonds, since most small stones are cut there.

Diamonds come in all sizes: 20% of which are gem-stone quality, the remainder are industrial diamonds. Most diamonds are tiny: gem-stone quality diamonds must be larger than most diamonds found, because of their use. Gem-quality diamonds must be visible, which is not true for industrial diamonds. Your answer, then, by logic, dictates that most diamonds an average diamond is much smaller than a pea.
