Defile in Sapphire: A Geological Record

# # # Defile in Sapphire: The Geological Record and the Key to the Identity of Gems

In mineralogy, Sapphire is a corundum that has a crystalline structure in the trigonal system, and has a basic chemical formula of $ext {Al} _ 2 ext {O} _ 3 $. Inclusions that appear inside the structure are not just blames, but witnesses of geological history. Let's see how important these defects are in terms of gemological value.

* * 1.Rutile and Silk Phenomenon * * *

The interesting defile in sapphire has a rutile that can affect beauty, especially in sapphire from a velvet-like cashmere.

- * * Velvet Texture Characteristics: * * The needle line will be tiny and create light scattering to look soft.

- * * Seaweed Phenomenon: * * Zilg-Lined Area Angled $60 ^ {extcircled {°}} $Create Sapphire Star

* * 2. Healed Fractures * *

The occurrence of cracks in times of gas or solution, water allows the healing of cracks in crystals, telling us the history of their formation.

* * 3. Color Zoning * *

Some sapphire have trace element absorption that affects color, which varies from growth to growth stage.

- * * Straight Color Stripes: * * that clearly shows

* * 4.Solid Mineral Inclusions * *

Sapphire also contains other types of mineral crystals that allow experts to identify more of its sources.

* * 5. Atomic-level chemical reactions and thermal quality improvement * *

The improvement in sapphire quality is due to chemical reactions that cause changes in color.

* * Conclusion * *

The defile in Sapphire is the 'signature of nature' that tells the story and purity state of Sapphire.
