Dazzling Gems: The Enchantment of Coated Quartz Crystals

Rainbow Quartz: A Piece of EnchantmentRainbow Quartz is a popular name in the gem industry for its mesmerizing aura that carries an iridescent sheen, with flashes of gold, purple dominantly. Its prismatic effect on light gives it eternal popularity and royalty status, making it a gemstone for all occasions.

However, most people often wonder whether Rainbow Quartz is real. This article aims to provide a straightforward and informative guide to help readers understand what Rainbow Quartz is, how it is made, and how to differentiate between natural and treated Rainbow Quartz.

Part One: Is Rainbow Quartz Real? Rainbow Quartz goes by several names, including Aura Quartz, Mystic Quartz, Angel Aura Quartz, and Titanium Aura Quartz.

However, it is crucial to understand what Rainbow Quartz is and how it occurs naturally in the environment. Rainbow Quartz is a mixture of natural crystal quartz, which is then treated with a titanium or niobium coating.

This coating forms a thin layer on the quartz, which alters the color and creates an iridescent, rainbow effect.

Moreover, Rainbow Quartz has several variations based on its metal coating.

For instance, the Titanium Aura Quartz has a metallic sheen with a dominantly purple and gold color. On the other hand, the Aqua Aura Quartz has a beautiful blue color with flashes of gold, while the Angel Aura Quartz comes with an angelic appearance displaying cream, pink, and purple colors in a metallic iridescence.

Part Two: Natural vs. Treated Rainbow Quartz

Natural Rainbow Quartz occurs naturally in the environment; however, it does not have the metallic coating that creates the prismatic effect that the treated one has.

The natural rainbow effect occurs due to the internal rainbow reflections that it gets from crystal imperfections. On the other hand, treated Rainbow Quartz involves coating the crystal with metals such as titanium, cobalt, and niobium to create the desired color and sheen effect.

The alteration of natural Rainbow Quartz by technology or exotic materials affects its value, making it less expensive. The treated Rainbow Quartz, although it may resemble and offer similar visual effects, isn’t a naturally occurring mineral, which, in turn, can affect its value and authenticity.

Therefore, it’s crucial to have a keen understanding of how to differentiate between the two types when purchasing Rainbow Quartz. Part Three: How Is Rainbow Quartz Made?

Rainbow Quartz is made through a Chemical Vapor Deposition (CVD) process that involves depositing metals onto the surface of crystals. The CVD process begins by placing quartz crystals in a vacuum chamber.

The chamber is then heated with high heat resistance, which creates a magnetron that extracts the metal, boiled until it reaches a vaporized state. The vapor is then deposited onto the quartz crystal, forming a thin layer that coats the crystal’s surface.

The process of cleaning and coating the Rainbow Quartz requires careful attention to detail. The crystal must be cleaned and rid of any organic matter that may interfere with the metal composition.

The metal used must also be in the right amount to ensure that the coating does not form thick layers that affect the optical effects.


Rainbow Quartz is an excellent choice of a gem for any occasion. Its unique visual effects make it a standout choice and exhibit an exquisite sense of luxury.

The article has provided a comprehensive guide on Rainbow Quartz, helping readers understand and differentiate naturally occurring Rainbow Quartz from the treated one. The manufacturing process has also been broken down into an understandable process so that buyers have an insight into what they are purchasing.

Whether for personal adornment or as a gift for a loved one, Rainbow Quartz is an ideal choice that never disappoints. 3) What Types of Coated Quartz Are There?

Quartz crystals when treated with metallic coatings create a wide variety of unique and eye-catching gemstones. Different metals result in different hue variations, giving each crystal its own special character.

Here are some of the coated quartz types available and their distinguishing features.

Overview of Coating Metals

Titanium This metal is the most common for coating quartz. It creates a magnificent iridescent effect on the crystals, much like an oil slick in rainbow colors.

Gold The resulting gold-colored coating on crystals emanates radiance and luxury and adds warmth to the design. Platinum The platinum coating provides a beautiful silver glow, lighter in color than titanium.

Indium Indium yields a rich blue color on crystals and is valued for its uniqueness and rarity. Lead Lead is used as a coating to deepen and darken the crystal’s color, giving it a distinct rich and luxurious feel.

Chromium The chromium coating creates a deep green hue in the crystal, evoking a sense of calm and serenity with its deeper appearance. Bismuth Bismuth coated quartz yields unique swirling patterns with metallic tinges of magenta and blue-purple.

Color Effects on Different Crystals

Mystic/Rainbow Quartz Mystic quartz has a combination of titanium and platinum coating, resulting in a magnificent array of colors. It boasts an attractive range of purple and blue hues on a white or transparent background.

Rainbow Quartz offers similar effects but creates an iridescent sheen, with flashes of gold and purple. Aqua Aura Quartz The beautiful blue color with flashes of gold comes with this crystal due to the combination of titanium and niobium coating.

This crystal often exhibits a cloud-like quality, making it mesmerizing to behold. Angel Aura Quartz Angel Aura undergoes a treatment process of titanium and silver coating, resulting in an angelic appearance displaying cream, pink, and purple colors in a metallic iridescence, creating a fairy-like quality.

Tanzan Aura Quartz The Tanzan Aura Quartz undergoes similar treatment as the Angel Aura, but its colors are significantly deeper and bolder, including blue, green, and gold, resulting in a very mystical appearance. Citrine Yellow-orange quartz gets its color from heat treatment instead of coating.

The heat changes the color of the crystal by creating irradiation flows, creating a yellow to amber color range on the crystal. Topaz Topaz is both natural and treated.

The Mystic Fire Topaz is treated topaz, which exhibits an array of colors similar to Mystic Quartz. Topaz can also have coatings like other crystals, providing distinctive looks and unique qualities.

4) Note on Topaz

Topaz, when treated, undergoes the same coating process as other crystals to give it a new appearance. However, naturally occurring topaz also offers different characteristics in color.

Natural topaz ranges from colorless to light blue and yellow, with the most valuable natural topaz being the blue variety. Blue topaz often undergoes irradiation and heat treatment to improve its color, making it more expensive and valuable.

The Mystic Fire Topaz, a variety of treated topaz, has a coating that creates an incredible combination of colors such as blue, green, and purple on the stone. Topaz has a unique method of coating, which utilizes a thin layer of chromium and iron oxides to create a thicker layer of iridescence.

The result is a stunning, multi-colored crystal that is ideal for any piece of jewelry.


In conclusion, coated quartz crystals offer an array of options in creating exquisite pieces of jewelry. From the stunning blue hues of indium coated crystals to the luxurious radiance of gold coated quartz, each coating provides something unique.

The Dazzling Mystic Fire Topaz is a testament that topaz, both naturally occurring and treated, can undergo coating that results in remarkable, distinctive gems. The possibilities are endless with coated quartz crystals get creative with your designs!



In summary, coated quartz crystals offer an array of unique and eye-catching gems, each with its own special character. Coating metal options like titanium, gold, platinum, indium, lead, chromium, and bismuth produce various color effects that create distinct visual appeal.
