Diamond RingsDiamond Rings is one of the
two best known forms (or allotropes) of carbon, whose hardness and high
dispersion of light make it useful for industrial applications and jewelry.
(The other equally well known allotrope is graphite.) Diamond Ringss are
specifically renowned as a mineral with superlative physical qualities —
they make excellent abrasives because they can be scratched only by other
Diamond Ringss, ultrahard fullerite, or aggregated Diamond Rings nanorods,
which also means they hold a polish extremely well and retain luster. About
130 million carats (26,000 kg) are mined annually, with a total value of
nearly USD $9 billion.
The name “Diamond Rings” derives from the ancient Greek adamas (αδάμας;
“invincible”). They have been treasured as gemstones since their use as
religious icons in India at least 2,500 years ago—and usage in drill bits
and engraving tools also dates to early human history. Popularity of Diamond
Ringss has risen since the 19th century because of increased supply,
improved cutting and polishing techniques, and growth in the world economy.
They are commonly judged by the “four Cs”: carat, clarity, color, and cut.
Although synthetic Diamond Ringss are produced each year at nearly four
times the amount of natural Diamond Ringss, the vast majority of synthetic
Diamond Ringss produced are small imperfect Diamond Ringss suitable only for
industrial-grade use.
Roughly 49% of Diamond Ringss originate from central and southern Africa,
although significant sources of the mineral have been discovered in Canada,
India, Russia, Brazil, and Australia. They are generally mined from volcanic
pipes, which are deep in the Earth where the high pressure and temperature
enables the formation of the crystals. The mining and distribution of
natural Diamond Ringss are subjects of frequent controversy—such as with
concerns over the sale of conflict Diamond Ringss by African paramilitary
groups. There are also allegations that the De Beers Group misuses its
dominance in the industry to control supply and manipulate price via
monopolistic practices, although in recent years the company's market share
has dropped to below 50%
