In-depth Analysis in Gemological Science: Diamonds and Moissanites

# # # In-depth Analysis in Gemological and Mineralogical Sciences: Diamonds and Moissanite

* * 1.Chemical composition and crystal structure * *

The fundamental difference that determines the properties of the two minerals is their chemical structure.

* * * Diamond: * * It consists of pure C carbon in the Cubic System, which has the highest symmetry, making it isotropic.

* * * Moissanite: * * * Synthesized from silicon carbide (SiC) in the Hexagonal System, causing anisotropic light and double refraction.

* * 2.Advanced optical properties * *

The behavior of light through gems helps distinguish:

* * * Refractive Index (RI): * * RI diamonds at 2.417, but higher moissanite is between 2.648 and 2.691.

* * * Light distribution value: * * Diamond has a value of 0.044 while Moissanite 0.104.

* * * ghosting phenomenon: * * Moissanite has double refraction. When viewed through a 10-fold camera, two edges can be seen.

* * 3. Response to different lighting conditions * *

* * * Indoor lighting conditions: * * Show near-diamond white brightness.

* * * Extreme sunshine conditions: * * Show clear rainbow spectrum separation

* * 4. Other physical properties * *

* * * Hardness: * * Diamond 10 Moissanite 9.25.

* * * Specific Stability: * * Diamond 3.52 Moissanite 3.22.

* * * Glow: * * About 30-40% of diamonds have blue fluorescence.

* * Conclusion * *:

Gemologists rely on understanding and observing the behavior of gems to identify a certain identity.
