Moissanite Presentation
Introduction:
Good morning
Moissanite is a mineral, which was discovered in fragments of the meteorite at Diablo Canyon crater in Arizona. ...
However, due to the very limited supply of the mineral naturally it is man made synthetic Moissanite, which is used in jewellery and the other main uses of it: semi-conductors and abrasion.
The creation of synthetic Moissanite is a very modern discovery as it was only in 1995 that Cree research developed the technology and process to produce a single large crystal of (silicon carbide). ... This synthetic Moissanite is chemically known as silicon carbide (SiC) and by the trade name Carbarundum, however in this presentation I will refer to it as Moissanite as it is the trade name currently describing synthetic SiC gemstones.
In this talk I am going to discuss the physical properties, which make Moissanite desirable in jewellery. ...
The Moissanite gem used in jewellery is a single clear transparent crystal which, because it is man made is free from natural defects and grain boundaries found in diamond and because it is transparent allows light to propagate through the medium. ... This enhances the natural sparkle of the Moissanite crystal and makes it even more desirable.
Refractive index:
I am now going to focus on the refractive index of Moissanite, which is one of the most important factors in jewellery. The refractive index of
Moissanite is particularly distinctive as it not only has a very high refractive index but also is doubly refractive. ...
However, Moissanite has a very high refractive index between 2. ...
DISPERSION
Hardness:
In my research of Moissanite I have discovered that Moissanite is very hard and that a Mohs scale is used to describe the hardness of solids, especially minerals.
