What is Turquoise: Ancient Blue Gemstone

Turquoise stands as one of the world’s oldest and most cherished gemstones, known for its distinctive blue to green coloration and rich cultural history. For thousands of years, this opaque gemstone has adorned everything from ancient Egyptian pharaohs’ burial masks to Native American jewelry. Its unique appearance combines a captivating color range with character-defining matrix patterns, making each piece distinctively unique. Jewelry enthusiasts, collectors, and curious observers alike continue to be drawn to this historic stone for its beauty, cultural significance, and enduring appeal across civilizations.

Turquoise Properties: Hardness, Color and Formation

Turquoise is a hydrated phosphate of copper and aluminum with the chemical formula CuAl₆(PO₄)₄(OH)₈·4H₂O. It forms over millions of years when water containing copper and aluminum leaches through host rocks, eventually crystallizing in the cracks and crevices. The distinctive blue color comes primarily from copper, while iron content can shift the hue toward green shades.

• Turquoise ranks 5-6 on the Mohs hardness scale, making it relatively soft compared to many gemstones. This softness means it can be scratched by many common items and requires careful handling in everyday wear.
• The stone displays colors ranging from sky blue (most valued traditionally) to blue-green, apple green, and yellowish-green. The color variation depends primarily on the amount of copper (blue) versus iron (green) in its chemical composition.
• Matrix patterns—the dark, web-like veins or patches within turquoise—are actually the host rock in which the turquoise formed. These patterns can range from thin spider-web lines to thick patches and significantly affect both the appearance and value of the stone.
• Natural turquoise is porous and can absorb oils, moisture, and chemicals from skin contact, cosmetics, or cleaning products. This porosity can cause color changes over time, sometimes referred to as the stone “taking on character.”
• Most commercial turquoise undergoes some form of treatment, including stabilization (infusing with resin or polymer), waxing, or hardening to improve durability, enhance color, and reduce porosity.
• High-quality natural, untreated turquoise with good hardness and minimal matrix commands the highest prices in the market, with “Persian grade” or “Sleeping Beauty” varieties being particularly sought after.

Due to its unique physical properties, turquoise requires different care than harder gemstones. Its distinctive color, often described as “turquoise blue,” has become so iconic that it has given its name to this particular shade in our color vocabulary. Despite its relative softness, turquoise’s beauty and cultural significance have maintained its value and popularity in jewelry for thousands of years.

Historical Uses and Cultural Significance of Turquoise

Turquoise has one of the longest documented histories of any gemstone, with evidence of human use dating back at least 7,000 years. Its name derives from the French phrase “pierre turquoise” meaning “Turkish stone,” as Turkish merchants first introduced it to Europe, though most of their material came from Persian (now Iranian) mines.

• Ancient Egyptians mined turquoise in the Sinai Peninsula as early as 3200 BCE, using it for jewelry, amulets, and ceremonial items. The famous funerary mask of King Tutankhamun features prominent turquoise inlays, demonstrating its importance in royal contexts.
• Persian (Iranian) turquoise, particularly from the historic mines near Nishapur, has been considered the quality standard for thousands of years. The pure, robin’s-egg blue variety without matrix has traditionally been the most valued type worldwide.
• Native American cultures of the Southwestern United States have a profound relationship with turquoise dating back over 1,000 years. The Ancestral Puebloans, Navajo, Zuni, and Hopi peoples all developed distinctive styles and techniques for working with the stone that continue to influence jewelry design today.
• For the Aztec and Maya civilizations of Mesoamerica, turquoise was often more valuable than gold. They used it extensively in mosaic work, masks, and ceremonial objects, associating it with water, fertility, and protection.
• In Tibet and Nepal, turquoise has been treasured for centuries as a protective talisman and used in traditional jewelry, often combined with coral and silver. The stone is believed to connect the earth and sky and offer protection to travelers.
• Chinese artisans have worked with turquoise for over 3,000 years, particularly favoring it for intricate carvings, inlay work, and as embellishments for headdresses and ornaments for nobility.

Throughout human history, turquoise has transcended its role as a decorative material to become deeply embedded in religious, spiritual, and cultural traditions across multiple civilizations. Its widespread use across diverse cultures—from the American Southwest to the Middle East, Asia, and beyond—speaks to its universal appeal. Even today, turquoise remains strongly associated with many of these cultural traditions, particularly Native American jewelry arts where it continues to be a living, evolving tradition rather than merely a historical artifact.

Different Types of Turquoise

Turquoise varieties are typically named after their mining locations, each with distinctive characteristics in color, hardness, and matrix patterns. These regional differences give each type its unique identity and value in the market. Quality turquoise is increasingly rare as many historic mines have been depleted or closed.

• Sleeping Beauty turquoise from Arizona is famous for its solid sky-blue color with little to no matrix. Since the mine’s closure in 2012, this variety has become increasingly valuable as existing supplies dwindle. Its pure, robin’s-egg blue color makes it highly desirable for fine jewelry.
• Kingman turquoise, also from Arizona, displays a range of blue shades with distinctive brown or black matrix patterns. It’s one of the few American mines still in substantial production and is known for its hardness and ability to take a high polish.
• Bisbee turquoise, from the Bisbee copper mine in Arizona, features an intense deep blue color often with a chocolate-brown matrix. Production ended in the 1970s, making authentic Bisbee material highly collectible and valuable.
• Persian (Iranian) turquoise is the historical standard for quality, characterized by its pure, intense blue color without matrix. The famous mines near Nishapur have produced exceptional material for centuries, though political situations have complicated its export in recent decades.
• Chinese turquoise typically has a greener hue than American or Persian varieties and often features distinctive matrix patterns. While historically significant, it’s generally considered less valuable than its American or Persian counterparts in today’s market.
• Tibetan turquoise tends toward greener shades and is often highly valued for its spiritual significance rather than gemological qualities. Traditional Tibetan jewelry frequently combines turquoise with coral and silver in distinctive, culturally significant designs.
• Nevada turquoise includes several varieties from different mines, including Lander Blue (extremely rare with spider-web matrix), Number 8 (known for its deep blue color), and Carico Lake (famous for bright green varieties).

The variety and distinct character of different turquoise types have created a specialized collector’s market where the provenance, mining location, and distinctive features of each stone become part of its value and appeal. As historic mines close and existing material becomes scarcer, authenticated turquoise from specific well-known sources continues to appreciate in value, particularly for larger, high-quality specimens with distinctive characteristics.

Turquoise Jewelry: Popular Styles and Settings

Turquoise has been a favorite material for jewelry across cultures and throughout history. Its distinctive color and versatility have made it adaptable to numerous styles, from ancient Egyptian amulets to contemporary designer pieces. The stone’s relatively soft nature requires thoughtful setting and design choices to ensure durability.

• Native American turquoise jewelry, particularly from Navajo, Zuni, and Hopi artisans, represents some of the most recognized styles, featuring distinctive silverwork, cluster settings, inlay techniques, and characteristic shapes like squash blossoms and concho belts.
• Turquoise is commonly paired with silver, which complements its blue-green colors beautifully. This combination has become iconic, particularly in Southwestern and Mexican jewelry styles.
• While traditionally set with silver, turquoise also works well with yellow gold, which creates a striking color contrast and has become increasingly popular in contemporary fine jewelry designs.
• Common setting styles for turquoise include cabochon settings (with smooth, rounded stones), inlay work (where pieces of turquoise are fitted into metal channels), and beaded styles (using drilled turquoise beads).
• The stone is frequently combined with complementary materials like coral, lapis lazuli, mother-of-pearl, and various shells in multicultural jewelry styles.
• Turquoise is versatile enough to be carved into beads, cabochons, small sculptures, inlay material, and even used as a ground material in techniques like micro-inlay.
• Due to its porosity and relative softness, protective settings like bezels (which surround the stone’s edge with metal) are often preferred over prong settings to prevent damage.

From ancient royal adornments to contemporary fashion statements, turquoise jewelry has maintained its popularity across thousands of years. The stone’s ability to complement both traditional and modern designs has ensured its ongoing presence in jewelry fashion. Whether in an authentic Native American piece with cultural significance or a contemporary designer creation, turquoise continues to attract jewelry lovers with its distinctive color and character.

How to Clean and Care for Turquoise

Turquoise requires more careful handling than many harder gemstones due to its porosity and moderate hardness. Proper care can significantly extend the life and preserve the beauty of turquoise jewelry, preventing color changes, structural damage, and deterioration over time.

• Avoid exposing turquoise to chemicals, including soaps, detergents, perfumes, hairspray, and household cleaners, as these can penetrate the stone and cause color changes or damage.
• Never clean turquoise jewelry in ultrasonic or steam cleaners, as the heat and vibration can cause cracking, color changes, or deterioration of any treatments or stabilizers.
• Clean turquoise gently using only a soft, slightly damp cloth. For more thorough cleaning, use a soft brush (like a baby toothbrush) with mild, lukewarm water and dry immediately and thoroughly with a soft cloth.
• Store turquoise jewelry separately from harder gemstones and metals to prevent scratching. Ideally, keep pieces in individual soft pouches or wrapped in a soft cloth.
• Remove turquoise jewelry before swimming in pools or hot tubs, as chlorine can damage both the stone and metal settings. Similarly, avoid wearing during heavy sweating or exposure to saltwater.
• Natural oils from skin contact can actually benefit turquoise over time, creating a pleasing patina—often described as the stone “taking on character.” This is different from damage and is considered desirable by many collectors.
• Avoid prolonged direct sunlight or heat exposure, as this can fade the color of turquoise and potentially damage any stabilizing treatments.

With proper care, turquoise jewelry can be enjoyed for generations and even improve in appearance over time as it develops a natural patina. Understanding turquoise’s unique properties helps owners make informed decisions about when to wear their pieces and how to maintain them. Though it requires more careful handling than diamonds or sapphires, many enthusiasts find that turquoise’s distinctive beauty makes the extra care worthwhile.

How to Identify Authentic Turquoise

With the high value of quality turquoise and increasing scarcity from historic mines, the market has been flooded with imitations, synthetics, and enhanced stones that can be difficult to distinguish from natural material. Knowing how to identify authentic turquoise helps collectors and jewelry buyers make informed purchases.

• Howlite, a white stone with gray markings, is commonly dyed blue to imitate turquoise. Look for unnaturally bright blue colors, color concentrations in the cracks, or spots where dye has worn away to reveal white underneath.
• “Block” or “chalk” turquoise is reconstituted turquoise dust mixed with resins and dyed to create a uniform appearance. This material lacks the natural variations and matrix patterns of genuine turquoise and may feel lighter or warmer to the touch.
• Plastic or resin imitations can be identified by their lightness, warmth to the touch, and lack of natural variation. A hot needle test (touching a heated needle to an inconspicuous spot) will melt plastic but not damage genuine turquoise.
• The “scratch test” can help identify some imitations—genuine turquoise can be scratched with a knife or steel file due to its 5-6 hardness, while many plastics will show different scratch patterns. However, this test should only be done on an inconspicuous area.
• Price can be an indicator—extremely inexpensive “turquoise” jewelry, particularly from mass-market sources, is unlikely to contain high-quality natural material. Genuine, high-grade turquoise commands significant prices.
• When examining turquoise, look for natural variations in color and matrix. Perfectly uniform color without any variation is rare in natural stones and may indicate a manufactured product.
• Reputable sellers should be willing to disclose any treatments or enhancements. Terms like “stabilized,” “enhanced,” “treated,” or “reconstituted” indicate the material is not completely natural, though it may still contain real turquoise.

Distinguishing between genuine and fake turquoise often requires experience and sometimes specialized testing. For significant purchases, consider consulting a gemologist or specialist in turquoise. Building a relationship with reputable dealers who specialize in turquoise, particularly those with connections to established mines or Native American artists, can also help ensure authenticity. Remember that treated or stabilized turquoise is still real turquoise—it has simply been enhanced for durability, which is common practice in the industry.

Metaphysical Properties & Healing Beliefs of Turquoise

Throughout history, turquoise has been attributed various healing and metaphysical properties across different cultures. While scientific evidence doesn’t support these claims, the stone’s rich tradition of spiritual and protective associations makes these beliefs an important part of its cultural heritage.

• Many Native American traditions consider turquoise a sacred stone that connects earth and sky, facilitates communication with the spirit world, and offers protection to the wearer. It’s often associated with rainfall, fertility, and overall good fortune.
• In crystal healing practices, turquoise is considered a stone of communication, encouraging clear expression and creative thinking. It’s often recommended for those in creative fields or those who struggle with public speaking.
• Turquoise is believed by some practitioners to have purification properties, allegedly helping to neutralize negative energy and electromagnetic smog from computers and environmental pollutants.
• In traditional Middle Eastern cultures, turquoise was often used as a protective talisman against the “evil eye,” bringing good fortune and preventing harm. This belief led to the tradition of gifting turquoise jewelry to protect loved ones.
• Some alternative healing traditions suggest turquoise may help with respiratory issues, immune system support, and detoxification, though again, these claims have no scientific basis.
• In chakra healing practices, turquoise is associated with both the throat chakra (communication) and the third eye chakra (intuition), supposedly helping to balance and open these energy centers.
• Ancient Tibetan shamans used turquoise in healing rituals and as protection for horse riders, believing it could prevent falls and provide safety during travel.

While these metaphysical associations aren’t scientifically verified, they represent important cultural beliefs that have contributed to turquoise’s value and significance throughout human history. For many collectors and enthusiasts, these traditional associations add an extra dimension of meaning and connection to their turquoise jewelry, regardless of whether they personally attribute spiritual properties to the stone.

Turquoise as a December Birthstone

Turquoise is one of the three traditional birthstones for December, alongside tanzanite and zircon. As a birthstone, it carries special significance for those born in this month and is often given as a birthday gift with personal meaning.

• December’s birthstone has been associated with good fortune, success, and prosperity, making it both a meaningful and attractive gift choice for those born in this month.
• As a birthstone, turquoise is thought to bring protection to the wearer, a belief that dates back thousands of years across multiple cultures.
• For December-born individuals who don’t connect with the traditional blue color of turquoise, the stone’s natural color variations from blue to green provide options that might better suit personal taste.
• Turquoise has the distinction of being one of the oldest known birthstones, with connections to birth month traditions dating back to ancient civilizations.
• In modern birthstone jewelry, turquoise is often set in both traditional styles reflecting its cultural heritage and contemporary designs that showcase its distinctive color.
• Ancient lore suggests that turquoise birthstone jewelry given as a gift will bring good fortune to both the giver and the recipient, strengthening their relationship.
• For those born in December, wearing their birthstone is traditionally believed to bring enhanced good fortune and intensified metaphysical properties compared to others wearing the same stone.

As a December birthstone, turquoise offers a connection to both ancient traditions and personal significance. Its rich history and distinctive appearance make it a meaningful gift that goes beyond mere decoration to represent protection, good fortune, and personal connection. Whether chosen for its traditional significance or simply for its beautiful color, turquoise birthstone jewelry carries layers of meaning for December-born recipients.

Turquoise Meaning and Symbolism

Turquoise has accumulated rich symbolic meanings across various cultures throughout its thousands of years of human use. These symbolic associations have contributed significantly to the stone’s enduring popularity and cultural importance beyond its aesthetic appeal.

• In Native American cultures, particularly among Southwestern tribes, turquoise symbolizes the connection between sky and earth, representing life-giving water and the protective sky above. It’s often considered a bridge between worlds.
• Ancient Egyptians associated turquoise with Hathor, goddess of joy, feminine love, and motherhood. They believed the stone represented the joy of living and offered protection in the afterlife.
• Persian culture viewed turquoise as a symbol of heaven on earth, with its sky-blue color representing celestial perfection. It was often used to decorate important religious buildings and manuscripts.
• In many cultures worldwide, turquoise has been considered a protective talisman for travelers, supposedly preventing falls from horses in ancient times and now sometimes given to modern travelers for safe journeys.
• The stone is widely regarded as a symbol of wisdom and truth, believed to promote honest and clear communication—a symbolism that aligns with its association with the throat chakra in more recent New Age traditions.
• Many cultures consider turquoise a stone of friendship and connection, which has led to the tradition of gifting turquoise jewelry to strengthen bonds between friends and loved ones.
• In Tibetan culture, turquoise represents the clear blue sky and is associated with openness, truth, and spiritual enlightenment.

These rich symbolic associations have helped turquoise transcend its role as merely a decorative material to become a meaningful cultural touchstone. For many people who wear or collect turquoise, these symbolic meanings add depth and significance to the stone beyond its beautiful color. Whether chosen for personal spiritual reasons, cultural heritage, or simple appreciation of its history, turquoise carries with it thousands of years of human meaning and connection.
