A
diamond is a transparent crystal of tetrahedrally bonded
carbon atoms and is the hardest natural material known.Natural
diamonds are formed at high-pressure high-temperature
conditions existing at depths of 140 to 190 kilometers
in the Earth mantle over periods from 1 billion to 3.3
billion years. Diamonds are brought close to the Earth
surface through deep volcanic eruptions by a magma,
which cools into igneous rocks.
Diamonds can also be produced synthetically in a high-pressure
high-temperature process which approximately simulates
the conditions in the Earth mantle. Special gemological
techniques have been developed to distinguish natural
and synthetic diamonds.
The mined rough diamonds are converted into gems through
a multi-step process called "cutting". Diamond
cutting is a delicate procedure requiring skills, scientific
knowledge, tools and experience. Its final goal is to
produce a faceted jewel where the specific angles between
the facets would optimize the diamond luster.

Diamond
Clarity refers to the tiny, natural
imperfections that occur in all diamonds. Gemologists
refer to these imperfections by a variety of technical
names, including blemishes and inclusions, among others.
Diamonds with the least and smallest imperfections receive
the highest clarity grades. The number, size, color,
relative location, orientation, and visibility of inclusions
can all affect the relative clarity of a diamond. |
