Diamonds Everything

Not only does the diamond trade control distribution, perpetuating the illusion of rarity to maintain their high price, and yet not only can we grow diamonds in a lab that are identical and superior to natural, geogenic diamonds; but humans themselves can actually become diamonds. Humans themselves can actually become diamonds. 

The "memorial diamond" refers to the use of a deceased person's body to create the carbon base for diamond formation, but there is nothing that says you can't do it while you're still alive.

Life Everlasting.

Memorial Diamond
Carbon can be obtained from cremated human or animal remains in a particulate or gaseous form. The carbon is then filtered using a conventional filtering technique. The carbon and other elements are then purified and graphitized, for example by a halogen purification technique.

Diamonds are Forever, and Ever, and Ever

On Art and Human Self-Domestication
"One of the best ways for the boy to prove he has resources is to give the girl something that is both expensive and useless."
-The Art Instinct, Denis Dutton, 2009, p154

Our regard for something beautiful "is commonly, in great measure a gratification of our sense of costliness masquerading as beauty".

Earth's gold came from colliding dead stars - Jul 17, 2013

"We estimate that the amount of gold produced and ejected during the merger of the two neutron stars may be as large as 10 moon masses - quite a lot of bling!" says lead author Edo Berger of the Harvard-Smithsonian Center for Astrophysics (CfA).

The team calculates that about one-hundredth of a solar mass of material was ejected by the gamma-ray burst, some of which was gold. By combining the estimated gold produced by a single short GRB with the number of such explosions that have occurred over the age of the universe, all the gold in the cosmos might have come from gamma-ray bursts.

Diamonds in the sky: Scientists find Jupiter and Saturn are awash in diamonds
Oct 09, 2013,

Recent work by planetary scientists has indicated that the deep atmospheres of Jupiter and Saturn may contain chunks of diamond floating in a liquid hydrogen/helium fluid.

'Diamane': Diamond film possible without the pressure
Feb 3, 2014

Perfect sheets of diamond a few atoms thick appear to be possible even without the big squeeze that makes natural gems.

Researchers at Rice University and in Russia have calculated a "phase diagram" for the creation of diamane. The diagram is a road map. It lays out the conditions – temperature, pressure and other factors – that would be necessary to turn stacked sheets of graphene into a flawless diamond lattice.

In the process, the researchers determined diamane could be made completely chemically, with no pressure at all, under some circumstances.

Turning graphite into diamond
Mar 28, 2014

Hydrogenated Graphene = Diamonds
A research team led by SLAC scientists has uncovered a potential new route to produce thin diamond films for a variety of industrial applications, from cutting tools to electronic devices to electrochemical sensors.
The scientists added a few layers of graphene – one-atom thick sheets of graphite – to a metal support and exposed the topmost layer to hydrogen. To their surprise, the reaction at the surface set off a domino effect that altered the structure of all the graphene layers from graphite-like to diamond-like.

"hydrogenation of graphene could be a new route to synthesize ultrathin diamond-like films without applying pressure" -Kaya

The discovery was unexpected. The original goal of the experiment was to see if adding hydrogen could alter graphene's properties in a way that would make it useable in transistors, the fundamental building block of electronic devices. Instead, the scientists discovered that hydrogen binding resulted in the formation of chemical bonds between graphene and the platinum substrate.

Diamonds are a quantum computer's best friend, August 2014

...nitrogen atoms which can occupy two different spin states are injected into a small diamond. Every nitrogen defect is trapped in an optical resonator made of two mirrors. Via glass fibres, photons are coupled to the quantum system consisting of the resonator, the diamond and the nitrogen atom. This way, it is possible to read and manipulate the state of the quantum system without destroying the quantum properties of the spins in the diamond.

[but later the article mentions the need for error correction codes, which requires billions of these diamonds - if I understand correctly.]

Scientists use 'smallest possible diamonds' to form ultra-thin nanothreads, Dec 2014

["Super Diamonds"] 'Direct writing' of diamond patterns from graphite a potential technological leap, Nov 2014

What began as research into a method to strengthen metals has led to the discovery of a new technique that uses a pulsing laser to create synthetic nanodiamond films and patterns from graphite, with potential applications from biosensors to computer chips.
"The biggest advantage is that you can selectively deposit nanodiamond on rigid surfaces without the high temperatures and pressures normally needed to produce synthetic diamond," said Gary Cheng, an associate professor of industrial engineering at Purdue University.

The technique works by using a multilayered film that includes a layer of graphite topped with a glass cover sheet. Exposing this layered structure to an ultrafast-pulsing laser instantly converts the graphite to an ionized plasma and creates a downward pressure. Then the graphite plasma quickly solidifies into diamond. The glass sheet confines the plasma to keep it from escaping, allowing it to form a nanodiamond coating.

"These are super-small diamonds and the coating is super-strong, so it could be used for high-temperature sensors," Cheng said.

Inside Beijing's airpocalypse – a city made 'almost uninhabitable' by pollution
Oliver Wainwright, The Guardian, Dec 2014

His proposal, developed in partnership with scientists at the Technological University of Delft in the Netherlands, uses buried coils of copper to create an electrostatic field that attracts smog particles, creating a kind of halo of clean air above it. “It’s similar to how static electricity attracts your hair,” Roosegaarde says. “We charge the smog particles and suck them to the ground.”

He has also developed a mobile version which uses the same technology, but housed in a vertical totem-pole structure that sits atop a small temple-like pavilion, akin to those found in Beijing’s parks. It’s here where the real alchemy will happen. “We’re going to turn dust into diamonds,” Roosegaarde says. “We will condense a 1,000 cubic metres of smog down into a millimetre-cube carbon crystal – which we will set like a diamond on a ring.” When you buy a smog ring, he says, you’re effectively donating 1,000 cubic metres of clean air to the city.

“I like the idea that you can take a problem and turn it into something desirable,” Roosegaarde adds. “Of course it’s not a practical solution, but I’m hoping that smog jewellery will get people talking about the problem – and when they see these clear circles of blue sky above the parks, they’ll demand clean air for the whole city.”
