Kingman Turquoise, with its distinctive blue and green hues, is a highly sought-after gemstone. Known for its exceptional quality and unique appearance, this turquoise variety has captivated jewelry enthusiasts and collectors for centuries. However, distinguishing genuine Kingman Turquoise from imitations or other turquoise types can be a challenging task. In this comprehensive guide, we will explore the key features and techniques for identifying Kingman Turquoise, ensuring that you can confidently recognize and appreciate this exquisite gemstone.
I. The Origins of Kingman Turquoise
Before delving into the identification process, it’s essential to understand the origins of Kingman Turquoise. Kingman Turquoise is mined near the Kingman, Arizona, area, which has a rich history of turquoise production. It is renowned for its remarkable color, ranging from sky blue to deep green, making it one of the most prized and recognized varieties of turquoise worldwide.
II. Recognizing Genuine Kingman Turquoise
Here’s how to identify genuine Kingman turquoise:
1. Color and Hue
The most distinctive characteristic of Kingman Turquoise is its captivating color. Authentic Kingman Turquoise typically exhibits shades of vibrant blue with subtle green undertones. The blue can range from a pale sky blue to a deep, rich shade. However, the intensity and consistency of the color may vary from stone to stone.
a. Sky Blue: Some Kingman Turquoise gemstones are known for their bright, sky-blue color. This delicate and light shade is a hallmark of this variety.
b. Greenish-Blue: The presence of greenish tones in the blue is a characteristic trait of many Kingman Turquoise pieces. This interplay between green and blue gives the gemstone its unique appeal.
While the color is a critical factor, it’s important to note that the appearance of Kingman Turquoise can change over time due to exposure to light and other environmental factors. Therefore, it’s crucial to consider multiple features when identifying the stone.
2. Matrix or Host Rock
A distinguishing feature of Kingman Turquoise is the presence of a distinctive matrix or host rock. The matrix consists of the surrounding rock material that the turquoise forms within. Authentic Kingman Turquoise is often found embedded in a reddish-brown to black matrix, which creates a beautiful contrast with the blue and green colors of the gemstone. The matrix can take on various patterns, such as spiderweb or pyrite, adding to the uniqueness of each stone.
a. Spiderweb Matrix: This pattern resembles intricate spiderwebs, with thin black lines crisscrossing the turquoise. This is a highly desirable feature in Kingman Turquoise.
b. Pyrite Matrix: In some cases, the matrix may contain golden pyrite inclusions, which can further enhance the stone’s visual appeal.
3. Texture and Luster
The texture and luster of Kingman Turquoise can provide valuable clues when identifying it. This gemstone typically has a waxy to vitreous luster, giving it a glossy and polished appearance. Genuine Kingman Turquoise feels smooth to the touch and is free from surface irregularities, such as scratches or dull spots.
When examining the surface, look for a consistent and even luster. While Kingman Turquoise can vary in quality, high-quality pieces will exhibit a brilliant shine that enhances their overall allure.

III. Identifying Imitations and Look-Alikes
Recognizing authentic Kingman Turquoise is a crucial step in gemstone identification. However, it’s equally important to be aware of common imitations and look-alikes that can be mistaken for the genuine stone.
1. Dyed Howlite and Magnesite
Howlite and magnesite are two minerals often used as substitutes for turquoise. To mimic the appearance of Kingman Turquoise, these stones are frequently dyed to replicate the blue and green colors. While they may resemble the real thing at first glance, they lack the matrix and texture characteristics of genuine Kingman Turquoise.
2. Reconstituted Turquoise
Reconstituted turquoise is composed of small turquoise fragments and other materials that are combined and stabilized to create a composite gemstone. These composites can look very similar to natural turquoise, but the absence of a natural matrix and the uniform appearance can be telltale signs of a reconstituted stone.
3. Stabilized Turquoise
Stabilized turquoise is a genuine turquoise that has been treated with resins or other stabilizing agents to enhance its durability and color. While it is still considered natural turquoise, it may not have the same value as untreated, high-quality Kingman Turquoise. It is essential to distinguish between stabilized and untreated Kingman Turquoise when evaluating the value of a specimen.
4. Synthetic Turquoise
Synthetic turquoise is a man-made gem created in laboratories. It can be challenging to differentiate from natural turquoise without specialized equipment. Synthetic turquoise lacks the matrix and inclusions typically found in authentic Kingman Turquoise.
IV. Expert Tips for Identifying Kingman Turquoise
To become proficient in identifying Kingman Turquoise, consider the following expert tips:
1. Use of UV Light
Ultraviolet (UV) light can be a useful tool for gemstone identification. Under UV light, Kingman Turquoise may exhibit a characteristic greenish-blue fluorescence. This fluorescence is a strong indicator of its authenticity.
2. Seek Professional Appraisals
When in doubt, it’s wise to seek professional gemological appraisals from accredited laboratories or experienced gemologists. They have the knowledge and equipment to provide accurate assessments.
3. Comparison with Reference Materials
Building a reference collection of Kingman Turquoise samples can help you become more proficient at identification. By comparing your specimens to known examples, you can refine your skills over time.
4. Consult Reputable Sources
Buying Kingman Turquoise from trusted sources is crucial. Reputable dealers and jewelers are more likely to offer genuine Kingman Turquoise and provide the necessary documentation to verify its authenticity.
V. The Significance of Kingman Turquoise
Kingman Turquoise is not just a valuable gemstone but also a symbol of heritage and culture. The Navajo and Pueblo people of the Southwest United States have a deep connection to Kingman Turquoise and have been using it in their traditional jewelry and art for generations. Its significance is not limited to its beauty; it is also a representation of a rich cultural history and the spiritual importance of turquoise in their traditions.
