Origin, Colors, and Qualities of Natural Turquoise

Turquoise, with its timeless allure and captivating hues, has been cherished by people for millennia. Understanding its formation, color variations, and matrix characteristics can deepen our appreciation of this gemstone's enduring beauty

Formation of Turquoise

Turquoise forms through a sedimentary process in dry regions, such as Arizona. When rainwater filters through soil and rock, it dissolves minerals like copper and aluminum. As this mineral-rich water evaporates, it leaves behind deposits that, over time, crystallize into turquoise. This process typically occurs near the Earth's surface under heat and pressure, resulting in turquoise's characteristic porous structure. 

Color Range and Influencing Factors

The color spectrum of turquoise spans from light to medium blue and extends to greenish blue. The specific hue depends on its chemical composition and the presence of trace elements. Copper imparts a blue coloration, while iron can introduce greenish tones. At Maui Divers Jewelry, we utilize colors that mimic the iconic blue waters of Hawaiʻi. 

Veining and Matrix Patterns

Turquoise often contains remnants of its host rock, known as the matrix, which appear as veins or splotches within the stone. Depending on the surrounding rock type, these patterns can range from dark brown to tan. The "spiderweb" pattern, characterized by a network of thin, web-like lines, is particularly sought after for its aesthetic appeal. While some prefer turquoise without matrix, others value these unique patterns, especially when they create a balanced and attractive design. When choosing turquoise, remember that beauty is always in the eye of the beholder.

Evaluating Turquoise Quality

When evaluating turquoise, factors such as color uniformity, the presence and appearance of the matrix, and the stone's ability to take a good polish are crucial. High-quality turquoise showcases a consistent medium blue hue, minimal matrix, and a smooth, polished surface. However, individual preferences play a significant role, and some collectors and designers seek stones with distinctive matrix patterns for their unique and fascinating character. 

In essence, the enduring allure of turquoise lies in its diverse color palette and the intricate matrix patterns that tell the story of its geological journey. Whether you favor a pristine blue gem or one adorned with natural veining, turquoise offers a timeless beauty that continues to captivate admirers worldwide.
