The Mystique of Turquoise: Unveiling Its Value and Rarity

Introduction to Turquoise

Turquoise is a unique and fascinating gemstone that has been prized for centuries for its beautiful blue-to-green color and interesting characteristics. While it may not be as well-known as some other gems, turquoise is a valuable and highly sought-after stone that has a rich history and culture surrounding it.

In this article, we will explore the characteristics, grades, and sources of turquoise, as well as the factors that affect its value.

Characteristics of Turquoise

Turquoise is a blue-to-green gemstone that is opaque, meaning that it does not allow light to pass through it. It has a Mohs hardness rating of 5 to 6, which makes it relatively soft and easily scratched or damaged.

Turquoise is made up of copper, aluminum, and gold, which combine to give it its unique color and texture. Turquoise comes in a variety of grades, ranging from low-quality to high-quality.

Low-grade turquoise is often stabilized to make it more durable and polished to improve its appearance. High-grade turquoise, on the other hand, is often left in its rough form and is highly valued for its natural beauty.

Sources of Turquoise

Turquoise is found in regions around the world, but some of the most valuable and prized turquoise comes from the American Southwest. Turquoise deposits are often located in areas where volcanic and sedimentary rocks have formed, and where aluminum-rich minerals are present.

Grades of Turquoise

The value of turquoise is largely determined by its grade, which is determined by factors such as appearance, color, weight, and source.

Appearance of Turquoise

The appearance of turquoise is an important factor in determining its value. High-quality turquoise is usually veined, lumpy, or pebbly and has a unique texture that makes it stand out.

Turquoise that has been formed in volcanic rocks is often smoother and less interesting in appearance.

Color of Turquoise

The color of turquoise is also an important factor in determining its value. Turquoise that has deep, rich colors is generally more valuable than lighter-colored turquoise.

The intrinsic qualities of turquoise can also play a role in determining its color, as local minerals can affect the shade and hue of the stone. Turquoise that has a robin’s egg blue color is highly coveted by collectors.

Weight of Turquoise

The weight of turquoise is another factor that can affect its value. High-quality turquoise is usually denser and heavier than lower-quality turquoise, which tends to be chalky and crumbly.

Turquoise that is easily worked, or carved into shapes and designs, is also considered to be a valuable specimen.

Source of Turquoise

The source of turquoise can also affect its value. Turquoise from certain locations, such as the Sleeping Beauty or Kingman mines, is considered to be of high-grade and is thus more valuable.

Turquoise deposits are often scarce and can become “played out” over time, which can drive up the price of remaining specimens.

Conclusion

Turquoise is a unique and fascinating gemstone that has a rich history and culture surrounding it. Its distinctive blue-to-green color and interesting characteristics make it a highly sought-after stone, and its value is determined by a number of factors such as appearance, color, weight, and source.

Whether you are a collector or simply appreciate the beauty of this fascinating gemstone, turquoise is a stone that is sure to captivate and inspire.

Other Factors Affecting the Value of Turquoise

Composition of Turquoise

In addition to the appearance and color of turquoise, the composition of the stone can also affect its value. Stabilized turquoise is often used for jewelry because it is more durable and less likely to break or crack.

This type of turquoise is usually infused with plastics or resins and is considered to be more usable for jewelry-making purposes. Unstabilized or natural turquoise is often used for display purposes, as it is more fragile and can be easily damaged.

While stabilized turquoise may be less valuable in some cases, it is still highly prized and sought-after by collectors.

Enhancement of Turquoise

Another factor that affects the value of turquoise is enhancement. Some turquoise is dyed to even out the color or saturation, which can improve its appearance.

Dyed turquoise can be of average or lower quality, but it can still be a valuable addition to a collection. In some cases, the enhancement is an intrinsic part of the value of the turquoise.

For example, turquoise that has been enhanced with gold content can be worth double its weight in gold. This type of turquoise is highly prized and is often used for fine jewelry and other luxurious items.

Veining of Turquoise

The veining of turquoise can also affect its value. Non-veined turquoise is considered to be clean and pure and is highly prized by collectors and jewelry makers alike.

Persian turquoise, which is a medium blue-green color, is often free of veining and is highly valuable. Gold veins in turquoise can also add to its value.

Gold-bearing turquoise is rare and highly coveted, as it is considered to be a unique and interesting specimen. Turquoise with gold veins can be found in a number of locations and is often highly prized by collectors.
