Angel Aura Quartz is a captivating mineral specimen known for its shimmering, rainbow-like surface. This ethereal appearance is not naturally occurring; instead, it results from a specialized process that permanently alters the surface of a natural crystal. The iridescent finish, often displaying soft pastel hues, is achieved through a controlled scientific technique. This treatment combines the durability of the natural stone with a striking, metallic aesthetic.
The Base Material
The creation of Angel Aura Quartz begins with selecting a high-quality base material, typically clear quartz. Manufacturers choose crystals with excellent clarity and minimal internal fractures, as the final aesthetic depends heavily on the quality of the original stone. The underlying quartz provides the structure, consisting of silicon dioxide molecules.
While clear quartz is standard, other varieties like amethyst or citrine are sometimes used to produce different color effects. The base material’s inherent characteristics, such as hardness, are retained during the process. The flawless nature and shape of the raw crystal are paramount because the surface treatment will amplify any existing imperfections.
The Process of Vapor Deposition
The distinctive iridescent coating is applied using a controlled procedure called Chemical Vapor Deposition (CVD). This method ensures the precious metals form a permanent bond with the quartz surface. The first step involves thoroughly cleaning the selected quartz crystals to remove any surface impurities that could interfere with bonding.
The prepared crystals are then transferred into a sealed vacuum chamber, which is designed to precisely control the environment. Next, the chamber is heated to an extremely high temperature, often reaching or exceeding 871 degrees Celsius (about 1600 degrees Fahrenheit). This intense heat prepares the quartz surface to accept the bonding materials at a molecular level.
Once the required temperature is reached, a pure metal or combination of metals is introduced into the vacuum chamber in a vaporized state. For Angel Aura Quartz, the metals are typically platinum and silver, which contribute to the stone’s characteristic pearly sheen. These metal vapors adhere to the heated quartz through electrostatic attraction, fusing a microscopic layer onto the crystal’s surface. This ultra-thin metallic film creates the brilliant, multi-colored reflection through optical interference.
Identifying Genuine Aura Quartz
Recognizing professionally treated Aura Quartz is relatively straightforward, as the bonding process creates a durable surface. Genuine Angel Aura Quartz has a molecularly bonded coating that will not chip, flake, or peel off when scratched. The durability comes from the use of specialized vacuum equipment and precious metals, which explains the higher cost of genuine pieces.
In contrast, lower-quality fakes often use simple paint or a thin dipping process that can be easily scratched or rubbed away. True quartz feels notably cold to the touch, unlike imitations made from plastic or glass that warm up quickly when held. Furthermore, a genuine quartz base will likely contain natural internal flaws or inclusions, whereas completely flawless, perfectly clear glass imitations may indicate a fabricated material.
