Diamond, an elemental mineral, is the hardest mineral on the Mohs scale of mineral hardness (10). It has a specific gravity of around 3.5, has conchoidal fracture, has a colorless streak, occurs in the isometric-hexoctahedral mineral crystal system, is an allotrope of carbon, exhibits perfect cleavage in three directions, has an adamantine luster, and appears in many colors from clear to black.

People who study diamonds are called gemologists. They specialize in identifying, grading, and evaluating the quality and characteristics of gemstones like diamonds.

Diamonds made in the laboratory are indeed diamonds. As gemstones, they are worth less than natural diamonds, given that all characteristics are equal: carat weight, colour, clarity and cut.
Diamonds, like all minerals, have a crystalline structure, a specific chemical composition, and are naturally occurring in nature.
A raw diamond has these geometric characteristics: its crystal habit is octahedral, and its crystal system is isometric-hexoctahedral (cubic).
'Chocolate diamonds' are named thus because this shade of brown diamond is the colour of chocolate. Some brown diamonds are natural diamonds; some brown diamonds are manufactured diamonds. A gemologist will help you determine the source of your brown diamond. Manufactured diamonds are always less expensive than natural diamonds with similar characteristics.
A scientist who studies gems such as rubies and diamonds is called a gemologist. They are experts in identifying and evaluating the quality and characteristics of gemstones.
Herkimer diamonds are double-terminated quartz crystals found in Herkimer County, New York, while true diamonds are carbon-based minerals. Herkimer diamonds have a lower hardness rating (7.5) compared to true diamonds (10). Additionally, herkimer diamonds are typically clear or smoky in color, whereas true diamonds exhibit a range of colors depending on impurities.
Gem-quality diamonds are described and judged on the individual cut, clarity, colour and carat weight of the cut and polished stone.
