sparkle that surpasses diamonds. Featuring a Mohs hardness of 9.25,
it is highly durable and suitable for everyday wear. Its
eco-friendly and sustainable nature, coupled with affordability,
makes it a popular alternative to diamonds. Champagne Moissanite
pairs beautifully with various jewelry designs, especially in
engagement rings, necklaces, and earrings, offering a touch of
elegance and uniqueness. Its timeless charm appeals to modern
consumers seeking beauty, value, and environmental responsibility.
Property
Moissanite occupies a place in the gemstone world for its unique
physical and chemical properties. Its high hardness, strong
dispersion, high refractive index and stable chemical properties
make moissanite a highly sought after gem material. At the same
time, with the continuous progress and improvement of synthetic
technology, the quality of moissanite is also constantly improving
and optimizing.
Chemical characteristic
1.Chemical composition: The main chemical composition of moissanite
is silicon carbide (SiC), which is a compound composed of carbon
and silicon elements.
2.Stability: The composition of moissanite is silicon carbide,
which is an atomic crystal with strong stability and is not easy to
undergo chemical changes. Therefore, in the daily wearing process,
Moissanite is not easy to yellow, fade or become blurred, and can
maintain its shiny appearance for a long time.
3.No radiation and harmlessness: whether natural moissanite or
synthetic moissanite, its essence is silicon carbide, does not
contain harmful radiation substances to the human body.
Physical characteristics
1.Color: Moissanite has a wide range of colors, including
colorless, blue, green, yellow-green, yellow, etc. Especially since
the introduction of the DF grade color synchronized with diamonds
in 2015, Moissanite is closer to diamonds in color and difficult to
distinguish.
2.Gloss and transparency: Moissanite has the same diamond luster as
diamond, and the transparency can vary from transparent to opaque.
Most moissanite is transparent colorless or nearly colorless, and
some are pale yellow.
3.Refractive index and dispersion: Moissanite has a refractive
index of 2.65-2.69, much higher than diamond's 2.42. Its dispersion
value of 0.104 is also more than twice that of diamond (0.044),
which allows moissanite to exhibit a more intense "fire color" in
light, that is, the colorful glow produced when light is reflected
and refracted inside the stone.
4.Hardness: Moissanite has a Mohs hardness of 9.25, second only to
diamond's 10, and is the second hardest gemstone in nature. This
hardness makes moissanite resistant to a certain degree of
scratching and wear during wearing.
5.Density and specific gravity: Moiscerite has a density of
3.20-3.24g/cm³, which is about 8.8%-10% lighter than diamond
(3.52g/cm³). This difference is reflected in the actual weight of
the stone, such as moissanite and diamond of the same diameter,
which will be lighter. According to the standard turning of round
diamonds, when the diameter is 6.5 mm, the weight of moissanite is
about 160 mg, and the weight of diamonds is about 200 mg.
6.Biaxial optical characteristics: Moissanite has biaxial optical
characteristics, and the observation of its ghost characteristics
depends on the Angle of observation. When viewed from the main
facet of the mesa, the ghosting effect is more obvious; When the
mesa is perpendicular to the moissanite axis c axis, the ghosting
effect will be reduced. This optical feature is completely
different from the crown reflection of a single refracted diamond.
7.Fire color: The accurate Moissanite section Angle can maximize
the light entering the interior of the moissanite repeatedly
refracted and reflected in the interior of the Moissanite without
penetrating, in which different wavelengths of light produce
different refraction, and finally transmitted from the crown table.
In this way, a beam of light entering the interior of the
Moissanite becomes dozens or even hundreds of beams of reflected
light of different colors, thus making the Moissanite appear bright
and colorful.
8.Inclusions: All identified moissanites contain a number of
inclusions, which are arranged in parallel needle-like patterns. In
some moissanite, thin, parallel rays can be seen. The presence of
these inclusions is one of the characteristics formed during the
natural or synthetic process of moissanite.
9.Crystal structure: Moissanite belongs to the hexagonal crystal
system, which means that its crystal structure has six axes of
symmetry. Under laboratory conditions, moissanite can crystallize
into 2-3 inch columnar crystals.

Application
Jewelry application
1.Fire and gloss: Moissanite has a higher refractive index and
dispersion value than diamond, which allows it to show more intense
fire and gloss in light. This unique optical effect makes
Moissanite more visually dazzling, becoming the first choice of
many jewelry lovers.
2.Color and transparency: Moissanite has a wide range of colors,
including champagne, colorless, blue, green, yellow-green, yellow,
etc., and most of them are transparent colorless or nearly
colorless. This high transparency and rich color selection provides
jewelry designers with more creative space to meet the aesthetic
needs of different consumers.
Scientific research application
Moissanite has significant value in the field of scientific
research, mainly reflected in the following aspects:
1. Materials science research
Composition and structure: The main component of moissanite is
silicon carbide (SiC), which plays an important role in materials
science. Through the study of moissanite, scientists can deeply
understand the physical and chemical properties of silicon carbide
and its stability under various conditions, providing a theoretical
basis for the development of new materials.
Synthesis technology: The artificial synthesis technology of
moissanite continues to improve, providing materials scientists
with an experimental platform to study silicon carbide crystal
growth, defect control and other problems. These studies help to
optimize the synthesis process of moissanite, improve product
quality, and promote the application of silicon carbide materials
in a wider range of fields.
2. High pressure physics and quantum materials research
In recent years, scientists have used silicon carbide (moissanite)
for in-situ magnetic detection of anvils under high pressure. The
defect structure such as silicon vacancy color center in silicon
carbide has potential application value in quantum information
science. This research method provides new ideas and technical
means for the research of high pressure physics and quantum
materials, and helps to reveal the physical properties and behavior
laws of materials under extreme conditions.
Q&A
Q:What are the synthetic methods of moissanite?
A: 1.High temperature and high pressure method (HTHP) : Raw materials
such as graphite and silica are put into high temperature and high
pressure equipment such as six-sided top press. Under conditions of
high temperature (usually more than 2000 °C) and high pressure
(usually more than 5 GPa), the raw material is broken down and
recombined to form silicon carbide (SiC) crystals. After a period
of growth, the required moissanite crystals are obtained. Finally,
the crystal is cut into a gemstone shape and polished.
2.Chemical vapor deposition (CVD) : This process uses steam
containing carbon and silicon as a raw material. At high
temperatures, these vapors are deposited on a special substrate and
gradually grow into silicon carbide crystals. Compared with the
high temperature and high pressure method, the chemical vapor
deposition method can control the crystal growth process and
quality more accurately. Similarly, after cutting and polishing,
the final Moissanite stone is obtained.
