History

Over a century ago, Nobel Prize winning scientist Dr. Henri Moissan began studying fragments left behind by an ancient meteorite. After close inspection, Moissan discovered qualities of a shimmering new mineral, with fire and brilliance never seen before.

Years later, this mineral was named moissanite in his honor. But despite his efforts and the extreme rarity of naturally occurring moissanite, it would take another century before moissanite would emerge as the brilliant jewel it is today.

Only after years of research, a breakthrough discovery by Charles & Colvard enabled the production of moissanite crystals large enough to cut into gemstones, inspiring us to create the finest moissanite jewelry, such as our three-stone rings, hoop earrings and pendants.

Charles & Colvard created moissanite was introduced in the summer of 1998, and, because of its superior hardness and brilliance surpassing even a diamond, self-confident women in over 60 countries now wear this stunning new jewel.


Unique Properties


Charles & Colvard created moissanite has unique physical properties that truly make it unlike any jewel ever seen. It is generally accepted that the most important characteristics of determining a diamond's value are based on the 4C's.

Beauty: The beauty of a jewel is determined by its color, cut, clarity and carat.
Cut: In order to maximize the fire and brilliance of a diamond, the cutter must place the angles and uniformity of facets in exact geometric relation to one another. This determines the diamond's ability to handle light which leads to brilliance.

All moissanite is cut to exact proportions where polish and symmetry are excellent. In addition, table percentages, crown angles and pavilion depths are ideal, which is a result of sharp, highly polished facets.

When moissanite is moved in various lighting conditions its excellent cut and symmetry results in superior fire.

Color: The color in most diamonds is very subtle and only trained gemologists can detect those variances. The D - to - Z scale describes the color range of diamond from absolutely colorless to light yellow. All moissanite is rated at "near-colorless" which is between the H - to - J range. While trace color can sometimes detract from the brilliance of a diamond, the combination of moissanite's high refractive index and excellent clarity and cut results in a jewel with superior brilliance.
Clarity: All moissanite stones are rated at a VVS2-VS2 clarity rating, which is very, very slightly included to very slightly included. Minute inclusions are very difficult to see under 10x magnification and are absent to the naked eye. The high clarity grading of moissanite results in consistent, superior brilliance.
Carat: Charles & Colvard created moissanite is offered in a range of sizes from 0.03 carats to over 7 carats.

Durability


The durability of a gemstone is determined by the following three characteristics:

  • Hardness: resistance to scratching
  • Toughness: resistance to chipping or cleaving
  • Stability: resistance to chemicals and temperature changes
Charles & Colvard created moissanite, at 9.25 Mohs, is incredibly tough and second in hardness only to diamond. During the development of moissanite jewels, extensive real-world wear tests were performed by many women in a variety of professions. These wear tests confirmed that moissanite jewels out-perform most precious gemstones in terms of durability, especially when set in precious metals such as platinum or gold.

The following pictures demonstrate the superior heat-resistance of created moissanite jewels compared to diamond.

 
A moissanite jewel and a diamond are placed in a high temperature oven. The temperature in the oven is increased and a flow of oxygen is introduced.
 
       
 
As the oven reaches 1100° C, the diamond catches fire and begins to vaporize. At this point, the heat to the oven is turned off and the diamond will continue to burn until...
 
       
 
...the diamond has completely vaporized. The moissanite jewel remains intact and as brilliant as the day it was created.
 

Charles & Colvard created moissanite has heat resistance properties superior to many other jewels, offering the following distinct advantages for using moissanite in fine jewelry.

Moissanite jewels can be cast in place, allowing us to offer you intricate yet classic designs, such as our beautiful Signature Collection. Moissanite jewels are less likely to experience heat damage during jewelry repair operations than most natural gemstones and can survive the extreme temperatures of typical house fires better than a diamond.


Brilliance and Fire


These photographs demonstrate why we feel Charles & Colvard created moissanite's superior brilliance and fire make it a jewel whose stunning beauty is unmatched by any other. Below, we compare a moissanite jewel's brilliance and fire to a diamond.

  A one carat diamond in water with a high intensity light shining on it.

The brilliance or refractive index (RI) of a diamond is its capacity to slow and bend light. Notice the length of the light specks and the size of the ring of specks around the diamond in proximity to the center.

The fire or dispersion is the separation of white light into its spectral colors.

The high refractive index (RI) which yields moissanite's superior brilliance, is clearly displayed by the increased length of the light specks and the larger size of the ring of specks in comparison to the diamond in photo 1.

The excellent fire or dispersion is clearly displayed by the deep, intense spectrum of color associated with each speck.

Superior brilliance and fire make moissanite created by Charles & Colvard unlike any other jewel.


Rarity


Charles & Colvard created moissanite is by far the rarest precious jewel on earth. Naturally occurring quantities of moissanite are so minute that they are not suitable for use in jewelry. After a century of research, only one company in the world is capable of growing moissanite crystals suitable for use as a precious jewel. Still the process is so complex, that it is as much an art as a science.




Charles & Colvard, Ltd. uses an uncommon combination of art and science to turn these rare jewel-quality crystals into a very limited quantity of created moissanite jewels.The chart shows the number of carats of Charles and Colvard created moissanite produced in 1999 in comparison to the millions of carats of the other four precious jewels imported into the United States.


Science and Art


After a century of research, only one company in the world is capable of growing moissanite crystals suitable for use as a precious jewel. Charles & Colvard uses our own uncommon combination of art and proprietary science to turn these rare jewel-quality crystals into stunning moissanite jewels.
Computer Modeling

The cutting specifications for moissanite jewels are designed to maximize the brilliance and fire inherent in the material. To maximize the light reflecting from a faceted moissanite jewel requires the design of shapes with proportions and angles unlike any other jewel.
Using computer modeling, we create proprietary designs to display the maximum light reflection based on the optical properties (i.e. fire, brilliance and luster) of moissanite jewels. A unique version of the round brilliant cut was the first shape developed applying these computer models. Recently we designed new fancy shapes that eliminate dark areas commonly found in other gemstones with these fancy cuts. We believe these proprietary designs enhance moissanite's physical properties for the superior optical performance observed in faceted moissanite jewels.


Quality


To ensure the highest quality, all created moissanite jewels are evaluated to exacting standards by specially trained gemologists, quality control personnel, and automated video imaging equipment.


Warranty


All Charles & Colvard created moissanite jewels come with the following 'Certificate of Authenticity and Limited Lifetime Warranty' card.
