Amora Moissanite - Color Enhanced Moissanite

Amora Moissanite
We are very pleased to introduce our new Amora Moissanite gemstones. Amora Moissanite is a Charles & Colvard created Moissanite gemstone made more perfect via a proprietary process invented by Better Than Diamond, Inc. and released in 2011. The process significantly whitens the Moissanite gemstones by at least 3 - 4 letter grades based on the GIA diamond color scale. Each Amora Moissanite gemstone comes with an independent lab color certification (something never before offered in Moissanite) and the girdle of the gemstone is laser inscribed for easy identification.

Amora Cert The process is based on the already established science of HPHT which stands for: High Pressure, High Temperature. It is 100% permanent, cannot be reversed, and has been used to whiten the color of diamonds for over a decade. The process in diamonds has been reviewed and studied extensively by the world's major gemological labs including GIA and EGL. They have found it to be permanent and not adversely affect the physical and optical properties of the treated diamonds (except to make them more colorless).
Amora Moissanite was previously named Mira Moissanite but was changed due to a trademark conflict. The underlying product is the same but a few of the stones in our stock are engraved 'Mira Moissanite'.
The hardness of the Amora Moissanite was recently tested at a major US university. The results found that the Amora enhancement increased the hardness by approximately 1.5%, making Amora Moissanite the hardest Moissanite ever made. It also is further proof that Amora is Moissanite perfected.

How it works
To help explain how HPHT works, it is easy to use diamonds as an example. Diamonds are formed under an extreme amount of heat and pressure in the crust of the earth. This environment allows carbon atoms to molecularly bond with each other and form a diamond crystal. However since it is happening naturally in an uncontrolled environment, the carbon atoms don't always bond perfectly, and so there are some molecules that don't form that perfect diamond lattice we see in the picture below.

By taking a diamond and re-introducing it into the same environment it was created using high pressure and high temperature (HPHT) it gives the carbon molecules in the diamond the opportunity to fix any broken bonds and form a more perfect crystal. Pressures of up to 70,000 atmospheres and temperatures of up to 3,600°F are used in the procedure. Because the final product has a more perfect crystal lattice than the original, untreated diamond, the process is permanent, non-reversible, and the diamond is now stronger since it has now been perfected.

HPHT and Moissanite
On a molecular level Moissanite is very similar to a diamond. Diamond is made of pure carbon where as Moissanite is made of Silicon (Si) and Carbon (C). The molecular bond between silicon and carbon is extremely strong which is what gives Moissanite its incredible hardness, toughness greater than a diamond, and its resistance to temperature that is also greater than diamond. These properties make treating a Moissanite via the HPHT process possible whereas other less stable gemstones (i.e. CZ) would shatter and then vaporize if placed in a similar environment.

When the raw Moissanite crystal was originally created by CREE (the lab that creates the Moissanites for Charles & Colvard) like the diamonds in nature, not all of the Silicon and Carbon bonds were made perfect. This is what gives Moissanite its characteristic color. By applying an HPHT process similar to diamonds, it gives the broken or imperfect molecular bonds in the Moissanite the opportunity to re-form. The result is a Moissanite that is more perfect and substantially more colorless. One way to think of it is that the Moissanite from C&C is the raw Moissanite, and the Amora Moissanite is Moissanite perfected.

Why Amora is more colorless
Light is energy. As light hits the Moissanite gemstone it applies very minute amounts of energy to the atomic bonds in the crystal. If the atomic bonds in the Moissanite are stronger than the energy applied, they will not react to the light, and thus, produce no absorbtion of the light and the crystal will be clear or colorless. Color is created when there are incomplete or missing atomic bonds. The electrons on these atoms that are not completely bonded will readily interact with incoming light, absorbing some of the frequencies and thus creating the visible color in the Moissanite. By applying the Amora HPHT process, the incomplete atoms have an opportunity to bond correctly.

Amora Warranty
Charles & Colvard's official stance is that this process violates the warranty. However once you understand what is happening on a molecular level, you can rest assured that the Amora Moissanite is a more perfect gemstone: whiter color and harder gemstone. Moreover if you read the print in the C&C warranty, they warranty only the optical properties of the gemstone, and it specifically states not to contact them for warranty related issues but to contact the company from which it is purchased. Since we guarantee the color of the Amora Moissanite will not change, whether you purchase a regular C&C Moissanite or an Amora, in the case of a warranty related claim, you will need to contact us. On just a side note, we have sold 100's of 1000's of Moissanite gemstones since 2005, and we have never had one warranty related claim.
