Diamond

Diamond is an allotrope of carbon. In areas of the world where diamonds are mined they often circulate as currency. Here we look to use raw diamonds as a natural resource to secure local financing of future film production.

In mineralogy, diamond (/ˈdəmənd/ or /ˈdmənd/; from the ancient Greek ἀδάμας – adámas "unbreakable") is a metastable allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at standard conditions.

Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools and the scientific applications in diamond knives and diamond anvil cells.

Because of its extremely rigid lattice, it can be contaminated by very few types of impurities, such as boron and nitrogen. Small amounts of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (lattice defects), green (radiation exposure), purple, pink, orange or red. Diamond also has relatively high optical dispersion (ability to disperse light of different colors).

Most natural diamonds are formed at high temperature and pressure at depths of 140 to 190 kilometers (87 to 118 mi) in the Earth's mantle.

Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth). Diamonds are brought close to the Earth's surface through deep volcanic eruptions by a magma, which cools into igneous rocks known as kimberlites and lamproites.

Diamonds can also be produced synthetically in a HPHT method which approximately simulates the conditions in the Earth's mantle.

An alternative, and completely different growth technique is chemical vapor deposition (CVD). Several non-diamond materials, which include cubic zirconia and silicon carbide and are often called diamond simulants, resemble diamond in appearance and many properties. Special gemological techniques have been developed to distinguish natural, synthetic diamonds and diamond simulants.

A diamond knife blade used for cutting sections for transmission electron microscopy. A diamond cutting edge is used as very thin (typically 70 to 350 nm) sections have to be cut from cells embedded in a hard substrate (such as epoxy resin). The diamond knife is mounted into an ultramicrotome for the cutting process. - wikipedia

One face of an octahedral uncut (rough) diamond, including scale. Note the trigons on the diamond surface. The diamond is 0.9 carats, white (approximately GIA 'E' grade), with no significant internal inclusions.

1974. The Hope Diamond, one of the largest of all blue diamonds, 45.52 carats, exhibited at the National Museum of Natural History. The gem is slightly lopsided, possibly because the bottom of the teardrop shape was cut away so that the original stolen jewel could not be identified. The setting is a circlet of smaller white diamonds on a chain of diamonds. - wikipedia
