Diamond is a mineral formed at very high temperatures and pressures, deep within the earth. Synthetic diamond is produced at pressures as high as 100,000 atmospheres (equivalent to 200 miles of rock!) and temperatures around 5,000° C. These conditions may approximate those of natural diamond formation.Web
Diamonds formed 90 million to 3 billion years ago at a depth of 90 to 400 miles beneath Earth's surface. Here, the extreme temperature (more than 2100°F [1150°C]) and pressure (45,000 times greater than sea level) …Web

Hand Specimen Identification. Native copper has a copper-red or pale rose-red color, and most commonly forms as scales of flakes (Figures 14.237 and 14.238), or branching arborescent crystals (Figure 14.239). It commonly tarnishes, has a hackly fracture, is malleability, and has high specific gravity.Web
In terms of it's physical properties, diamond is the ultimate mineral in several ways: Hardness: Diamond is a perfect "10", defining the top of the hardness scale, and by absolute measures four times harder than sapphire (which is #9 on that scale). Clarity: Diamond is transparent over a larger range of wavelengths (from the ultraviolet into the …Web
INTRODUCTION Diamond: A Key Sample to Study Earth's Interior.

Mineral - Classification, Properties, Types: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing …Web

The repetition and fixed symmetry of the elements in a mineral is what creates its rigid and solid structure. A mineral is a solid that is made of one element. For example, a diamond is made of pure carbon, making it a mineral. On the other hand, calcite is made of carbon and two other elements, calcium and oxygen.Web
