Why Is Some Turquoise Purple: Everything You Need To Know

by Madonna

Turquoise, renowned for its captivating blue and green hues, has long held a special place in the world of gemstones. However, a variant that has been making waves in recent times is purple turquoise. This distinct coloration has left many enthusiasts curious about its origins and the processes involved in its formation. In this comprehensive article, we embark on a journey to unravel the mysteries behind why some turquoise exhibits a mesmerizing shade of purple.

The Chemistry of Turquoise: A Spectrum of Colors

Before delving into the specific nuances of purple turquoise, it is imperative to understand the chemistry behind the coloration of turquoise itself. Turquoise is a phosphate mineral, and its characteristic blue and green colors arise from the presence of copper and aluminum. The intricate matrix patterns often seen in turquoise result from the incorporation of other minerals during its formation.


The color spectrum of turquoise can range from sky blue to green, with variations in intensity and hue influenced by the specific geological conditions during its creation. This natural diversity has been a significant factor in the allure of turquoise throughout history.


Nature’s Palette: The Role of Minerals in Turquoise Coloration

The vibrant colors exhibited by turquoise are a testament to the geological processes that occur over millions of years. Copper, in particular, plays a crucial role in imbuing turquoise with its characteristic blue and green tones. When copper is present in the mineral structure, it imparts a blue hue, while the presence of iron may contribute to greenish shades.


The host rock in which turquoise forms also influences its color. The matrix patterns, veins, and nodules that characterize turquoise are a result of its interaction with surrounding minerals, adding layers of complexity and uniqueness to each specimen.

The Emergence of Purple Turquoise: A Natural Rarity or Human Intervention?

Purple turquoise, with its distinctive and alluring purple hue, raises questions about its natural authenticity. Traditional turquoise enthusiasts, accustomed to the blues and greens of the natural spectrum, may be surprised by the introduction of this unconventional color. To demystify the phenomenon of purple turquoise, it is essential to explore the various factors that contribute to its unique coloration.

One of the primary contributors to the purple hue in turquoise is the presence of manganese. Manganese is a trace element that, when present in turquoise deposits, can manifest as shades of purple. This natural occurrence offers an alternative perspective, suggesting that not all purple turquoise is a result of human intervention or treatment processes.

Manganese: The Purple Alchemist in Turquoise Formation

Manganese, known for its diverse range of colors in the mineral kingdom, has a transformative impact on turquoise. When manganese is introduced into the mineral composition, it interacts with the existing elements, creating a spectrum of purple hues. This natural coloration process, distinct from treatments like the Mojave process, highlights the dynamic nature of turquoise formation.

The geological conditions under which turquoise forms play a crucial role in the concentration of manganese, influencing the intensity and shades of purple observed in the gemstone. While other factors, such as iron and copper, still contribute to the overall coloration, manganese emerges as the key alchemist responsible for the purple transformation.

The Natural vs. Treated Debate: Perspectives on Purple Turquoise Authenticity

In the gemstone industry, discussions around the authenticity of colored gemstones often center on the distinction between natural occurrences and human interventions. Purple turquoise, with its vibrant and unconventional color, becomes a focal point in this debate. Gemstone enthusiasts and collectors grapple with the question of whether the purple hue is a product of natural geological processes or a result of treatments.

It’s crucial to note that both natural and treated purple turquoise coexist in the market. The natural variants, where manganese has played a role in coloration, are cherished for their authentic beauty. On the other hand, treated versions, like those subjected to the Mojave process, undergo enhancements to achieve a specific color profile, raising considerations about the balance between natural authenticity and aesthetic preferences.

The Mojave Process: Enhancing Purple Turquoise Aesthetics

The Mojave process, widely utilized in the gemstone industry, is a treatment that involves enhancing the color and matrix patterns of turquoise. While it is not the sole method for achieving purple turquoise, it has become synonymous with creating vibrant and visually striking specimens. Understanding the Mojave process sheds light on how treated purple turquoise enters the market and influences consumer choices.

In the Mojave process, turquoise is stabilized, and a bronze-colored matrix is introduced to create the distinctive purple and blue hues. While this treatment is acknowledged and accepted within the industry, ethical considerations arise regarding the transparency of information provided to consumers. Awareness and disclosure become essential in navigating the choices between natural and treated gemstones.

Ethical Considerations: Transparency in Purple Turquoise Trade

As with any gemstone, transparency and ethical practices are paramount in the trade of purple turquoise. Consumers deserve to be well-informed about the origin and treatment processes their gemstones undergo. The ethical responsibility extends to jewelers and sellers, who must ensure that accurate and transparent information is conveyed to potential buyers.

Creating industry standards for disclosure and ensuring that treatments like the Mojave process are clearly communicated contribute to an ethical marketplace. Informed consumers can then make choices aligned with their values, whether they prioritize the untouched authenticity of natural purple turquoise or appreciate the enhanced aesthetics achieved through treatments.

The Geological Tapestry: Turquoise Formation in Diverse Landscapes

The geological conditions under which turquoise forms are diverse, resulting in variations in color, matrix patterns, and overall aesthetics. Turquoise deposits are found in arid regions, often associated with copper deposits. Exploring the geological tapestry of turquoise formation sheds light on the intricacies that contribute to the gemstone’s allure.

In some cases, purple turquoise may be found in regions where manganese-rich minerals are present alongside copper. The interplay of these elements, combined with specific geological conditions, leads to the creation of purple turquoise in its natural state. Recognizing and appreciating the geological tapestry of turquoise formation adds depth to the narrative of this captivating gemstone.

The emergence of purple turquoise, whether through natural manganese content or treatment processes, underscores the artistic expressions found in nature. Turquoise, with its spectrum of colors, matrix patterns, and unique formations, stands as a testament to the creative forces at play beneath the Earth’s surface.

Rather than viewing purple turquoise as a departure from tradition, it can be celebrated as an extension of the natural artistry found in turquoise. The diverse palette of colors invites us to explore and appreciate the richness of geological processes, recognizing that each variant, whether blue, green, or purple, contributes to the overall beauty of turquoise.
