diamond,
mineral, one of two crystalline forms of the element carbon
(see allotropy),
the hardest natural substance known, used as a gem and in
industry. |

Diamonds
crystallize in the isometric system (see crystal)
commonly as transparent to translucent white, colorless, yellow,
green, blue, or brown octahedrons (the familiar diamond shape).
The extraordinary brilliancy of diamonds after faceting is
due to their very high refractive index, which is greater
than that of any other naturally occurring gemstone. In addition
to the gem
varieties there are bort, which is poorly crystallized or
of inferior color and in fragmentary condition, and carbonado
(black diamond), which is gray to black and opaque, with poor
cleavage. Bort and carbonado are used as abrasives, in the
cutting of diamonds, and for the cutting heads of rock drills.
Diamond abrasives may have been used as early as 2500 B.C.
in China. |

The
earliest sources of gem diamonds were India and Borneo, where
they were found in river alluvium. All famous diamonds of
antiquity were Indian diamonds, including the Great Mogul,
the Orlov, the Koh-i-noor, and the Regent or Pitt. Other famous
diamonds are the Hope (blue), Dresden (green), and Tiffany
(yellow). In the early 18th cent., deposits similar to those
in India were found in Brazil, mainly of carbonados, though
they may have been known as early as 1670. In 1867, a stone
found in South Africa was recognized as a diamond. Within
a few years, this began a wild search for diamonds, both in
river diggings and inland. In 1870–71, dry diggings,
including most of the celebrated mines, were discovered. Well-known
South African diamond mines are the Dutoitspan, Bultfontein,
De Beers, Kimberley, Jagersfontein, and Premier. Botswana,
Namibia, and South Africa are now the world's major diamond-producing
nations; other important countries include Australia, Russia,
Brazil, Angola, Canada, Sierra Leone, Ghana, Tanzania, and
Venezuela. The use of diamonds to finance African rebel groups
and fuel civil strife in the 1990s led, in 2001 and 2002,
to international agreements (the Kimberly Process) designed
to certify legitimately mined diamonds.
Synthetic diamonds were successfully produced
in 1955; a number of small crystals were manufactured when
pure graphite mixed with a catalyst was subjected to pressure
of about 1 million lb per sq in. and temperature of the order
of 5,000°F (3,000°C). Synthetic diamonds are now extensively
used in industry.

Pink diamonds
have long been heralded as one of the most sought after
of gemstones. You will find that pink diamonds are more
difficult to find in jewelry stores. Pink diamonds are
much rarer than white diamonds. |
 |
|
There
are only a relatively small number of pink diamonds found
each year compared to white diamonds. The rarity and scarcity
of pink diamonds makes their price significantly higher than
their white diamond counterparts, leaving pink diamonds, out
of reach of most jewelry lovers. See pink
diamond rings here. |

Pink sapphires
occur in colors ranging from pale pinks, to deep pinks
and almost red colors. Pink sapphires are available
in pale pink colors similar to the color of most pink
diamonds. The deeper colors available in pink sapphires
are considered more appealing than pink diamonds by
many ladies. The majority of pink sapphires are priced
signficantly lower than pink diamonds. Pink sapphires
are priced a little above blue sapphires, making them
very affordable for the perfect engagement ring, dress
ring or wedding ring. See pink
sapphire rings here. |
 |
|
| |
| |
Pink sapphires
can be used in solitaire ring styles, or coupled with
white diamonds or other gemstones to highlight the pink
sapphire color. Pink sapphires can also be used with
different colors of pink sapphires for contrasting pink
hues. Many bridal and fashion magazines feature pink
sapphires and pink diamonds in white gold rings which
is making this pink and white combination very popular.

When
purchasing a diamond ring, you not only must decide on the
cut, but also how it is set in the ring. The most popular
diamond ring settings are the classic diamond solitaire setting.
The solitaire setting has a prong setting that allows your
diamond to be visible from all sides, thereby catching the
most light.
Cathedral Setting: In a cathedral setting,
a prong-set diamond lies flush with the setting. This setting
is more durable.
Prong-Set Side Stone Setting: Also called
a three-stone ring, this style is more brilliant with diamond
side stones. The prong-set side stones receive light from
all angles to reflect light.
Contour Setting: The contour setting is an
updated twist on the classic diamond solitaire style. The
prong setting lifts the diamond off the ring and allows it
to catch and reflect light.

A diamond's
color is just one of the characteristics you'll
take a look at when you shop for diamond
jewelry, but there's more to consider than the stone's
shade. There's fluorescence,
the tendency some diamonds have to shift color in different
lights. And there are diamond
color treatments to be aware of. Some make yellowish
diamonds more "white." Some make brownish
or yellow diamonds more
vivid--but not all treatments are permanent. Start
exploring diamond color before you go shopping so
that you'll understand the terms you read and hear in
ads. (Photo of Asscher cut diamond copyright Blue Nile)

Diamonds can
be damaged by impact. Some protection against impact
damage is afforded by the prongs of the mount which
shield the diamond. There is less protection, and a
greater potential for damage, with larger diamonds.
We suggest not wearing your diamond ring when engaged
in activities where the ring might be hit on hard objects,
such as sports or housework. |
 |
|
Loss
of diamonds can occur if the prongs of the mount are bent
out of place or worn. The prongs fit tightly against the diamond,
but still can be caught inadvertently on an edge and bent.
Inspect your ring periodically, and if a prong is bent or
the diamond loose have the diamond re-set. The protruding
ends of the prongs wear over the years and hold the diamond
less securely. Again, inspect the prongs periodically for
wear and if at all in doubt take your ring to your jeweler
for examination. |

Diamonds
have an affinity for skin oils, soap, cosmetics and grease.
Cleaning your diamond regularly will ensure its full brilliance
is visible. The simplest cleaning method is to wash in warm
water with any mild liquid detergent. Brush the diamond gently
with a toothbrush while in the sudsy water. Rinse under warm
running water then pat dry with a soft lint-free cloth. Take
care not to lose your ring down the drain! |
