ABOUT MOISSANITE |
| As seen on 20/20, Moissanite fools even professional
jewelers and conventional diamond testers. Charles & Colvard
created Moissanite is the only synthetic diamond that has an incredible
hardness rating of 9.25 out of 10 (10 being diamond) and has more
fire, brilliance and luster than diamond and is only one tenth the
costs of diamond.
Unlike other synthetic diamonds such as Cubic Zirconia, Moissanite
is made from silicon and carbon through a combination of heat and
pressure and has the closest physical properties to that of a diamond.
Therefore, when tested with a conventional diamond tester, Moissanite
passes as a “diamond”.
Just like diamond, Moissanite is scratch resistant and will never
fade, cloud or change colour after prolong wear.
All of our Moissanite jewels are accompanied by Charles & Colvard’s
Certificate of Authenticity and Limited Lifetime Warranty. |

HISTORY OF MOISSANITE |
Thousands of years ago, fragments
of a meteorite scattered across the Arizona desert when it crashed
on earth.
In 1893, Dr. Henri Moissan, a Nobel Prize winning scientist, discovered
natural silicon carbide in Arizona, while studying and analyzing
fragments of this meteorite near the Diablo Canyon or Meteor Crater.
Dr. Henri Moissan soon discovered the presence of very small quantities
of this mineral that has fire and brilliance never before seen on
earth. Upon further investigation and testing, it was discovered
that the mineral was made of silicon carbide. In honor of Dr. Moisson,
the mineral was named Moissanite in 1905.
Since it is very rare to obtain naturally occurring Moissanite
which is only found in minute quantities, years of research and
development was successful in discovering special techniques through
a combination of science and art to produce these special and rare
Moissanite crystals in a Lab.
It was in the late 1980’s when a North Carolina company named
CREE which is the world leader in the manufacture of silicon carbide
for electronic use, developed a process for producing large single
crystals of Moissanite. In 1995, scientists from CREE and Charles
& Colvard began a three year research initiative and technique
to properly cut the large crystals of silicon carbide into brilliant
new Moissanite jewels. |

PROPERTIES OF MOISSANITE |
Overall, Moissanite’s brilliance,
dispersion or fire and luster were all better than diamond. Moissanite
is unquestionably the most realistic diamond substitute ever created
where its hardness and scratch resistant properties are better than
all other gemstones and Cubic Zirconia. Below is a chart showing the
comparison between Moissanite and diamond.

Brilliance: Brilliance relates to the refractive index of
the jewel and is measured by the amount of light that enters the jewel
and reflected back to the viewer. Fire: Fire is
the dispersion of light in a jewel. It also refers to how light
breaks into the spectrum of colours and is measured by the amount
of coloured flashes viewed as the jewel is placed under different
lighting conditions.
Luster: Luster is the amount of light that the
jewel reflects back to the observer from the surface of the jewel.
Durability: Durability is the toughness, hardness
or the resistance to scratching, chipping or cleaving.

Obviously, there have been many attempts to imitate real diamond
due to its price and popularity. However, with the exception of
Moissanite, all of their attempts lack the brilliance, luster and
hardness of diamonds. Only Moissanite stacked up as the best diamond
simulant ever, and is made of similar carbon element as diamond
which is known for its hardness.
Physical Elements of Diamonds: They are the hardest
naturally occurring minerals consisting of pure carbon crystals
form tightly by the bonding to four other carbon atoms. Their hardness
is a result of the strength of the carbon bonds.
Physical Elements of Moissanite: Moissanite is
the only synthetic diamond that is made of Silicon Carbide (SiC)
which is also nearly as hard due to the presence of the carbon bonds.
It is created under extreme heat (1200 deg C) and pressure (50,000
atmospheres).

COLOUR AND CLARITY OF MOISSANITE |
| Moissanites are “H to J”
in colour which is similar to many diamonds which also fall into this
range of colour. It is still considered as a white colour, however
not as white-white like other synthetic diamond such as Cubic Zirconia
which is less believable since white-white colour diamonds are extremely
rare. See table below. Moissanites are typically VS1 in clarity
when using the diamond grading system as a benchmark. See table
below.
