Identifying A Diamond

Color is the color of the mineral. Diamond's color is usually a clear with no hue.

Luster is the way the surface of a mineral reflects light. Diamond's luster is adamantine.

Streak is what color the streak is after scratching the object(mineral) on another object(streak plate). Diamond's streak is white.

Cleavage/Fracture describe how a mineral breaks. Cleavage is a smooth cut, whilst fracture is a rough cut. Diamond is a form cleavage because it has smooth cuts.

Hardness is a minerals resistance to being scratched. Diamonds are extremely hard, therefore making them a 10.

Density is the measure of matter in a given amount of space. Diamond has a density of 3.5gm/cc.

Diaphaneity is the ability to see through a mineral. Diamond is transparent.

Special Properties are things that are special to something. Diamonds special properties are that they make excellent abrasives because they can be scratched only by other diamonds, diamond is the hardest natural material known, other specialized applications also exist or are being developed, including use as semiconductors, the toughness of natural diamond has been measured as 3.4 MN m-3/2.
