Identifying
Moissanite as jewelry
When Moissanite was first introduced in in the summer of
1998 some jewelers misidentified Moissanite as diamond. These
early errors occurred when thermal testers were used as
an aid to identification because the thermal conductivity
of Moissanite is very close to that of diamond. Once the
properties of Moissanite were fully known and understood
it became is easy to distinguish from diamond - Moissanite
is as it is doubly refractive and has a slight yellowish
/ greenish tint to the stones which becomes more noticeable
with increasing gem sizes. So what are the other differences
between stones created with Moissanite as opposed to diamonds?
What are the Pro's and Cons of Moissanite?
Quality
of Diamonds compared to Moissanite
Comparing
the quality of diamonds compared to Moissanite. The Cut,
Clarity, Color and Carat Weight all have a significant impact
on the cost of diamonds because these factors are all used
to value the price of a diamond. The Cut, Color, and Clarity
are used to measure the quality of the diamond and the Carat
is used to measure the weight of a diamond. The elements
of the 4C's have been used to compare Moissanite with diamonds
and the comparisons are detailed below.
The Pros and Cons of Moissanite - The Pro's
Facts and Information about the Pros and Cons of Moissanite
are as follows, starting with the Pro's of Moissanite
:
-
Cost - The cost of Moissanite is roughly an eighth
of the price of natural diamonds but is generally
more expensive than Cubic Zirconia at one tenth
of the price of natural diamonds
-
Appearance - Moissanite is so optically close to
diamond that even some jewellers cannot tell the
difference without the aid of various tests
Clarity - Moissanite is not separated into different
grades of Clarity like diamonds because each stone
must meet set specifications before being released
to distributors
-
The
set specifications of Moissanite are comparable
to diamonds which have been graded VS1-VS2 on the
Diamond Clarity
Chart
Inclusions / Flaws - Manufactured to appear more
like diamonds, Moissanite gemstones have
Inclusions
which is a plus-point when compared to the flawless
Cubic Zirconia - the growing process produces tiny,
unnatural, white, ribbon-like inclusions
Moissanite stones are equivalent to the H - J grades
in the white
Diamond
Color scale
-
Moissanite is not as white-white like the Cubic
Zirconia (which is equivalent to a perfect "D" and
therefore less believable imitation, as white-white
color diamonds are extremely rare
-
Hardness -
Hardness denotes resistance
to scratching
as opposed to Toughness which
relates to the ability to
resist breakage from falls or impacts.
-
Moissanite is much harder than most natural gems,
and Cubic Zirconia, at about 9.5 on the Mohs scale,
however it is nowhere near as hard as a diamond
at about 10.0 on the Mohs scale
-
Toughness - Moissanite is tougher than diamond because
it has no natural fractures that can crack if the
stone is subjected to an impact of some kind.
Moissanite has a slightly higher index of refraction
(brilliance) and much greater dispersion (fire)
than diamond
-
Moissanite to is better able to retain it's fire
if it gets dirty, oily, or smudged, whereas Cubic
Zirconia looks very dull when dirty. The excess
fire is seen as a 'pro' by some and a 'con' by others
Moissanite
- The Con's
Facts
and Information about the disadvantages or cons of the Moissanite
are as follows:
-
Jewelry containing synthetic gemstones like Moissanite
are not a good investment, they do not hold their price
-
Color - Has a slight yellowish / greenish tint which
becomes more noticeable with increasing gem sizes
-
Fluorescence - An undesirable hazy effect that causes
them to appear slightly green or yellow. The effect
of Fluorescence on Moissanite is much greater under
natural light or in sunlight. A jewelry dealer therefore
tends to show the stones under a pink tinged light as
this tends to cancel out the fluorescence.
-
Moissanite is highly birefringent (a birefringent crystal
splits a light beam into two) which is a desirable quality
in some optical applications, but is not desirable in
gemstones. Moissanite jewels are therefore cut along
the optic axis of the crystal to minimize birefringent
effects
-
Fire - Has more 'fire' or brilliance producing a more
synthetic effect. The high dispersion of 0.11 is apparent
in Moissanite (nearly 2.5 times greater than that of
diamond) and readily distinguishes it from diamond with
a dispersion of 0.04 which is virtually unnoticed. The
excess fire is sometimes considered cheap and fake looking
-
Hardness - Diamonds are harder than Moissanite
which is 9.5 on the Mohs scale compared to a diamond
at about 10.0 on the Mohs scale
-
Inclusions / Flaws - Manufactured to appear more like
diamonds, Moissanite gemstones have
Inclusions Also
natural flaws are absent in Moissanite replaced instead
by tiny, unnatural, white, ribbon-like structures that
are a result of the growing process.
-
Rarity - Moissanite is not rare and can be made quickly
and in vast quantities, whereas natural diamonds take
millions of years to form
-
Status and Wealth - It has not got the same status as
a diamond and does not indicate wealth
-
Symbolic Value - Diamonds have long symbolised love
and purity - Moissanite has no such symbolic value
What
is Moissanite? - Definition
What
exactly is what is Moissanite? Definition: It is a high
quality synthetic gemstone which imitates the appearance
of diamonds and is made in a lab. It is created with silicon
and carbon, through a combination of pressure and heat.
Moissanite is a trade name name given to silicon carbide
(chemical formula SiC) for use in the gem business. Moisanite,
Mossanite and Moisannite are all common mis-spellings for
Moissanite.

the 1990's and

History
Timeline of Moissanite
The
following timeline details the discovery and production
of Moissanite
History Timeline
Dates -
History Timeline Moissanite
1891 - In 1891
a chemist called
Dr. Henri Moissan
(1852-1907)
discovered carborundum
1892 -
In 1892, Henri Moissan theorized that diamonds
could be synthesized by crystallizing carbon
under pressure from molten iron
1893 - In 1893 Henri
Moissan discovered minute quantities of a new
mineral, natural silicon carbide. Henri Moissan
discovered the mineral in an ancient meteorite
found in the Diablo Canyon in Arizona. The silicon
carbide was later named "moissanite" in honor
of Dr. Moissan.
1905 - In 1905 mineral
silicon carbide was named "Moissanite" in honor
of Dr. Moissan
1906 - In 1906 Dr. Henri
Moissan was awarded the Nobel Laureate in Chemistry
in recognition of his investigation and isolation
of the element fluorine, and for the adoption
in the service of science of the electric furnace
which was called after him.
1960's - Scientists looked
at Moissanite as a new, versatile material for
use in optical applications
1974 - German scientists
used silicon carbide in their LCD's for computers
1980's - A North Carolina
company named CREE developed a proprietary process
for producing large single crystals of Moissanite
1995 - In 1995, Charles
& Colvard partnered with Cree (a NC-based R&D
lab) to develop gemstones using silicon carbide
1998 - Commercial production
of Moissanite began and Moissanite was introduced
in the summer of 1998. In conjunction with Cree,
Charles & Colvard is the exclusive worldwide
manufacturer and marketer of lab-created Moissanite
The above History Timeline provides details the discovery
and production of Moissanite and its use as an imitation
of diamond.
