Its steel grey, lightweight, and brittle in its pure form. It is found on Earth as a component in about 100 of 4000 known minerals. It occurs in precious forms such as emeralds and aquamarines.
Its is used mostly as a hardening agent in alloys.

Beryllium (pronounced /bəˈrɪliəm/) is a chemical element with the symbol Be and atomic number 4. A bivalent element, beryllium is a steel grey, strong, light-weight yet brittle, alkaline earth metal. It is primarily used as a hardening agent in alloys, most notably beryllium copper.
Beryllium is an essential constituent of about 100 out of about 4000 known minerals, the most important of which are bertrandite (Be4Si2O7(OH)2), beryl (Al2Be3Si6O18), chrysoberyl (Al2BeO4), and phenakite (Be2SiO4). Precious forms of beryl are aquamarine and emerald.
The most important commercial sources of beryllium and its compounds are beryl and bertrandite. Beryllium metal did not become readily available until 1957. Currently, most production of this metal is accomplished by reducing beryllium fluoride with magnesium metal.
Beryl is found most commonly in granitic pegmatites, but also occurs in mica schists in the Ural Mountains and is often associated with tin and tungsten orebodies. Beryl is found in certain European countries such as Austria, Germany, and Ireland. It also occurs in Madagascar (especially morganite).
The most famous source of emeralds in the world is at Muzo and Chivor, Boyacá, Colombia, where they make a unique appearance in limestone. Emeralds are also found in the Transvaal, South Africa, Minas Gerais, Brazil, and near Mursinka in Urals. In the United States emeralds are found in North Carolina. New England's pegmatites have produced some of the largest beryls found, including one massive crystal with dimensions 5.5 m by 1.2 m (18 ft by 4 ft) with a mass of around 18 metric tons. It is New Hampshire's State Mineral. Other beryl locations include South Dakota, Colorado, Utah, Idaho, and California.

The element Beryllium is an essential componenet of many elements on Earth. It is steel grey, and lightweight. It is also classified as a Carcinogen (cancer causing). Be used to be used for many purposes (ex: in lightbulbs and factories) but is now closely regulated because of medical problems.

The problem with this is simple: darkness isn't just literal shadow, or even what's literally unseen. Darkness is also what we aren't aware of, and what we don't pay _attention to_, either by accident or on purpose. Ideally, ok, sure, we'd have our conscience as a guide and we'd know when we're lying to ourselves, or when people are too busy seeking power to address what's needed and true. That's the ideal though--we live in a competitive if not relentless world, where people have to think of themselves and scrap FOR themselves from younger and younger ages. On the one hand, survival does in fact have its own morality, you can't BE a moral being if you don't exist anymore. But on the other, the notion that a so-called civilized people would LET the social darwinist idea of "kill or be killed" or "always compete and always take for ME AND MINE" run amuck does speak to an agenda that is fundamentally egoist and immoral. Not just amoral (where morality is absent) but improper morals where right and wrong are reflected into mirror images and counterpoints. In short we live in a world where we SELL people on the idea of abandoning conscience, on the idea of cheating, as a way to "win at all costs" and to get "what's rightfully ours" at any price. We may or may not take the idea itself seriously, but a lot of people make a living putting it out there. Then more people still make a _career_ out of exploiting the problem, but making sure it doesn't get solved so persecutions and witch-hunts get to go on _forever_. I'm not saying it's right, on the contrary. I'm saying this is what the world is made of lately. It's made of bullsh=t, corruption and violence, walking around on two legs and pretending to be human-ish. THAT is what makes money, power and fame these days, while ordinary people are routinely left to rot and/or exploited until they're used up and die. Evil gets coddled while good people are abused and neglected by turns, by the millions. Under the circumstances, I'd hope you could tolerate someone maybe putting some focus on the things nobody pays attention to, that nobody talks about. Drag some of these shadows into the light so we can see what they are. Granted, that could just be more ego talking too. That's a risk you take with it all. I get that.

Pure it is a steel coloured metal. It makes up the structures of emeralds and aquamarines.
