There are approximately 4000 different minerals, and each of those minerals has a unique set of physical properties. These include: color, streak, hardness, luster, diaphaneity, specific gravity, cleavage, fracture, magnetism, solubility, and many more. These physical properties are useful for identifying minerals.

Numerous mineral have been reported as DIs, some which have formed deep (>600 km) within the mantle and were only known from high-P experiments prior to their discovery as DIs. The presence of particular minerals in a diamond is the method for the geologic classification of diamonds into P (peridotite) and E (eclogite) types. (Fig. 12) (slide12/21)

Chemical properties are any of the properties of matter that can be observed and measured only by performing a chemical change or chemical reaction. Chemical properties cannot be determined by touching or viewing a sample; the structure of the sample must be altered for the chemical properties to become apparent.
