# Profile

## Lore

One of the Reflection, Black Diamond is the leader of the group. However since Reflection members operate alone almost all the time and is rather decentralized, leadership is loose and not required for the group to function.

As of the time Black Diamond is revealed, none of the other six members are known. Only much later did the second member, Imperial Topaz appeared.

Reflection is the counterpart faction of the Spectra, and the members have also fought in the ancient Revelation war.

In the past, Black Diamond seemed to be liked by her sister Diamond, who the latter often called her "Cooey". In return Black Diamond calls her "Dia" or "Big Sis".

## Personality

Black Diamond's personality is bright and direct. She's one that would easily attract the attention of others and naturally become the center of the spotlight.

If Diamond (as the House of Representatives) is a "leader who takes the initiative and takes the lead in times of turbulence", then Black Diamond is a "leader that everyone around her wants to follow." In short, it's comparing a professional leader that runs a big corporation, versus a casual leader in a large event that interacts with members that are eager to follow orders.

On the other hand, Black Diamond places great importance on "leaving things the way they are" and "being as they are", and she does not like forcing things or acting in secret.
Black Diamond does not hide her emotions usually, but will instantly swipe away any discussion on sensitive topics.

Due to a past conflict with the previous Star Savior and the Parliament, she has not hidden any of her disdain towards the government for shackling Diamond with political duties and refused to acknowledge the protagonist when first introduced.

# Mineralogy

**A curious stone often referred to as "black diamond", carbonado is more accurately described as a polycrystalline or aggregate material of amorphous carbon, graphite, and diamond. Black Diamond represents conquest, innovation, extinction, and birth.**

Carbonado, commonly known as black diamond, is one of the toughest forms of natural diamond. It is an impure form of polycrystalline diamond consisting of diamond, graphite, and amorphous carbon. It is found primarily in alluvial deposits in the Central African Republic and in Brazil. Its natural colour is black or dark grey, and it is more porous than other diamonds.

Natural black color in diamonds typically comes from the presence of many small, dark colored inclusions and fractures. Most black diamonds are opaque and have an almost metallic luster, though some may have a translucent “salt-and-pepper” appearance. Some diamonds with a black face-up color may have a dark brown or dark green body color, when viewed from the side.

Carbonado diamonds are typically pea-sized or larger porous aggregates of many tiny black crystals. The most characteristic carbonados have been found only in the Central African Republic and in Brazil, in neither place associated with kimberlite, the source of typical gem diamonds. Lead isotope analyses have been interpreted as documenting crystallization of carbonados about 3 billion years ago. The carbonados are found in younger sedimentary rocks.

Mineral grains included within diamonds have been studied extensively for clues to diamond origin. Some typical diamonds contain inclusions of common mantle minerals such as pyrope and forsterite, but such mantle minerals have not been observed in carbonado. In contrast, some carbonados contain inclusions of minerals characteristic of the Earth's crust; the inclusions do not necessarily establish formation of the diamonds in the crust, but because while the obvious crystal inclusions occur in the pores that are common in carbonados, they may have been introduced after carbonado formation. Inclusions of other minerals, rare or nearly absent in the Earth's crust, are found at least partly incorporated in diamond, not just in pores: among such other minerals are those with compositions of Si, SiC, and Fe‑Ni. No distinctive high-pressure minerals, including the hexagonal carbon polymorph, lonsdaleite, have been found as inclusions in carbonados although such inclusions might be expected if carbonados formed by meteorite impact.

Supporters of an extraterrestrial origin of carbonados propose that their material source was a supernova which occurred at least 3.8 billion years ago. After coalescing and drifting through outer space for about one and a half billion years, a large mass fell to earth as a meteorite approximately 2.3 billion years ago. It possibly fragmented during entry into the Earth's atmosphere and impacted in a region which would much later split into Brazil and the Central African Republic, the only two known locations of carbonado deposits.

The 67.5 carat "Black Orlov" is perhaps the most famous natural black diamond.
