WHERE DO THEY FORM?

Turquoise forms when water percolates through rocks containing copper, aluminum, and other minerals. A chemical reaction occurs, resulting in deposits of what we know as turquoise. That's a basic way of describing a process that takes millions of years and only occurs when a complex set of conditions come together.

MINING PROCESS:

The journey of a turquoise stone commences deep within the earth's crust, where mineral-laden veins gradually form over millions of years. Within these veins, turquoise emerges in its natural, unrefined state. Turquoise deposits are scattered across diverse regions worldwide, including the United States, Iran, China, and Mexico.

Once a promising turquoise deposit is identified, mining operations commence. Techniques employed vary depending on the size and location of the deposit, ranging from manual tools to sophisticated machinery. Miners meticulously extract turquoise-bearing rocks to minimize any potential damage to the stones.

Following extraction, the turquoise undergoes sorting and stabilization procedures. This involves evaluating its color, clarity, and hardness to distinguish high-quality stones from those of lower grade. In some cases, stabilization treatments are applied to enhance the stone's durability and color, ensuring it withstands the rigors of cutting and shaping processes.

Turquoise Sorting and Stabilization

Following extraction, turquoise undergoes a sorting process to distinguish high-quality stones from lower-grade materials. This assessment focuses on the turquoise's color, clarity, and hardness.

In certain cases, turquoise undergoes stabilization to enhance its durability and color. This involves impregnating the stone with a clear resin to prevent fading and brittleness over time. Stabilization also improves the stone's ability to take on a polish, facilitating easier handling during cutting and shaping.

Cutting and Slabbing

After sorting and stabilization, turquoise is prepared for cutting and slabbing. Skilled lapidaries use specialized equipment like diamond saws and grinding wheels to shape the raw turquoise into usable pieces.

In the cutting process, the lapidary meticulously assesses the stone to determine its ideal shape and size. Often, slabs flat pieces of turquoise are cut to maximize the stone's potential. These slabs can be further crafted into diverse jewelry components, including cabochons and faceted stones.

Beliefs About Turquoise:

In ancient times, turquoise was even regarded as a comforting material for the wearer. The Persian scholar Al-Qazwini, for instance, wrote: "The hand that wears a turquoise and seals with it will never see scarcity." Turquoise was often worn on turbans, sometimes surrounded by pearls, to protect the wearer from the "evil eye." As talismans, they adorned daggers, sabers, and horse bridles. It wasn't until the time of the Crusades that they came to Europe. Indeed, it is from that period that the name "Turquoise" originates, meaning "Turkish."

In South, Central, and North America, turquoise has also held a very special place among all gemstones. The Aztecs in Mexico, for instance, used to decorate their traditional masks with this stone, which was considered sacred according to their beliefs. The Native Americans, who still create a great deal of traditional silver jewelry with turquoise today, believe that the sky-blue gemstone establishes a direct connection between the sky and the sea.

Throughout the world, turquoise has been worn as a natural protective gemstone against the forces of darkness. If in ancient times they protected horse and rider from unexpected falls, they are now considered the protective stone of pilots, air crews, and other occupational groups exposed to a high level of risk.

In modern gemstone healing, those suffering from depression are advised to wear turquoise or a chain with turquoise beads. The optimistic color of turquoise is said to imbue quiet personalities with more confidence. It is a suitable gift to give, a stone of friendship, for turquoise is said to foster truthfulness and reliability in relationships.

Natural Occurrence

Iran (Nishabur and Kuh-e-Raies Mountain), Afghanistan, Tibet, China, USSR, Australia, Sinai Peninsula, and the USA (Arizona, California, Nevada, and New Mexico).

Available Colors

There is no ideal color for turquoise. The color depends on the chemical composition of the rocks. This is why none of the turquoise gems will have the same color. The color ranges between pale blue to bright green. High-quality turquoise is of a pure, glowing sky blue.
