The Influence of Trace Elements on Turquoise’s Color

Copper as the Primary Color Influencer

Copper is the primary trace element responsible for the iconic blue and green colors found in turquoise. The presence of copper ions within the crystal structure of turquoise absorbs certain wavelengths of light, resulting in the characteristic blue and green hues that are highly prized.

The exact amount of copper present determines the specific color of the turquoise. Higher copper content leads to more intense blues, while lower copper levels result in greener shades. Copper is also responsible for the striking color change phenomenon observed in certain turquoise stones, where the color transitions from blue in daylight to green in artificial light.

Other Trace Elements and their Effects

While copper is the primary color influencer in turquoise, other trace elements can also impact the gemstone’s color and overall appearance. Chromium, for example, can contribute to the formation of turquoise with a more greenish hue. Iron can introduce brown or reddish tints to the turquoise, adding depth and complexity to its color palette.

The presence and combination of these trace elements within the crystal structure of turquoise create a range of fascinating colors, making each stone a unique work of art. The delicate balance of these elements gives turquoise its distinct beauty and charm and adds to its allure as a gemstone.

Identifying Characteristics of Turquoise

Specific Absorption Lines in Turquoise

Turquoise possesses distinctive absorption lines in its spectrum that can help in its identification. When light passes through a turquoise gemstone, certain wavelengths are absorbed by the copper ions present. These absorption lines create gaps or dark bands in the gemstone’s spectrum, which can be viewed using specialized tools.

These specific absorption lines are unique to turquoise and serve as a key identifying characteristic. Gemologists and experts can analyze the absorption spectrum of a stone to determine whether it is genuine turquoise or an imitation.

Measurement of Specific Gravity

Specific gravity is another characteristic that can be used to identify turquoise. Specific gravity is the ratio of an object’s density to the density of water. Different gemstones have specific gravity values that fall within specific ranges, and turquoise has a specific gravity typically around 2.6–2.8.

To measure the specific gravity of a turquoise stone, gemologists use a precise method involving weighing the stone in air and then weighing it again when suspended in water. By comparing the two weights, the specific gravity can be calculated, providing additional information in the identification process.

Other Identifying Properties

In addition to specific absorption lines and specific gravity, turquoise possesses other identifying properties that can aid in its identification. These properties include its distinctive color and luster, Mohs hardness, and refractive index.

The color of turquoise, ranging from sky blue to blue-green, is its most recognizable characteristic and can often be used to distinguish it from other gemstones. Turquoise has a waxy to subvitreous luster, which gives it a smooth and slightly glossy appearance.

On the Mohs scale of hardness, turquoise typically ranges from 5 to 6, making it relatively soft compared to other gemstones. This means that turquoise is more susceptible to scratching and should be handled with care to preserve its beauty.

The refractive index of turquoise, which measures how light is bent as it passes through the gemstone, can also provide valuable information. However, refractive index alone is not sufficient for a conclusive identification, as it can vary depending on the specific variety and origin of the turquoise.

Distinguishing Natural and Synthetic Turquoise

Magnification and Observing Telltale Signs

To differentiate between natural and synthetic turquoise, experts often rely on magnification and observation of certain telltale signs. Under magnification, natural turquoise reveals its unique characteristics, while synthetic turquoise may exhibit different features.

Natural turquoise often displays a slightly irregular texture, with tiny pores and veins, indicating its organic origin. The matrix patterns, if present, also exhibit natural variations and intricacies. In contrast, synthetic turquoise may appear more uniform and possess a more artificial-looking texture.

Additionally, microscopic examination can reveal the presence of fillers or bonding agents, which are often used in the production of synthetic turquoise. These telltale signs, when observed under magnification, can aid in differentiating between natural and man-made turquoise.

Synthetic Turquoise and its Characteristics

Synthetic turquoise, also known as simulated or imitation turquoise, is created in laboratories to mimic the appearance of natural turquoise. Various techniques are used to produce synthetic turquoise, including the bonding of turquoise powder with resins or other materials.

Although synthetic turquoise can closely resemble natural turquoise in terms of color and appearance, it lacks the unique characteristics and properties found in natural stones. The distinct matrix patterns and identifying features present in natural turquoise are often absent in synthetic versions.

Furthermore, synthetic turquoise may exhibit a more vibrant or saturated color than natural turquoise. This is because synthetic stones can be manipulated to achieve specific hues, whereas natural turquoise obtains its color from trace elements and natural processes.

By carefully examining the stone’s characteristics and considering the absence of natural imperfections, experts can determine whether a turquoise stone is natural or synthetic.
