December, the final month of the year, is associated with a diverse collection of gemstones, each distinguished by its own unique color palette and rich historical significance. Unlike other months that typically feature a single birthstone, December offers a selection of four to five gemstones—blue topaz, blue zircon, tanzanite, and turquoise—each with its own distinct shade of blue and, in some cases, other vibrant colors. This diversity allows December-born individuals to choose a gemstone that not only complements their personal style but also resonates with their individual energy and personality.
The December birthstones are more than just beautiful jewels; they are steeped in history, lore, and cultural symbolism. From ancient civilizations that revered these gems for their supposed protective and healing properties to modern times where they are cherished for their beauty and rarity, December’s birthstones have a story that spans centuries. This article will explore the various December birthstones in detail, covering their geological properties, historical uses, cultural significance, and practical considerations for care and maintenance.
History and Lore
The December birthstones have a long and storied history, with each gemstone tracing its lineage to different civilizations and eras. Turquoise, for instance, has been revered for thousands of years, with evidence of its use dating back to ancient Egypt. Pharaohs and other Egyptian rulers adorned themselves with turquoise, believing it to bring health, good fortune, and protection. The stone was so highly valued that it was often used as a form of currency. In ancient China, turquoise was similarly treasured, with artisans carving it into intricate pieces over 3,000 years ago. These early uses underscore the enduring appeal of turquoise and its role as a symbol of protection and prosperity.
Zircon, another December birthstone, has an even older history. The name "zircon" is derived from the Arabic word zar (meaning gold) and gun (meaning color), a testament to its golden hues in its natural state. Zircon has been found in various parts of the world, including Thailand, Cambodia, Vietnam, Nigeria, and Australia. It has been used in jewelry for centuries, with some believing it to possess the power to relieve pain, increase appetite, and protect travelers from injury and disease. Zircon was also thought to welcome visitors warmly and ensure peaceful sleep without nightmares. These beliefs highlight the gemstone’s enduring place in both cultural and spiritual traditions.
Tanzanite, by contrast, is a relatively recent discovery, first identified in 1967 in Tanzania. Unlike the ancient histories of turquoise and zircon, tanzanite’s lore is more modern, though it has quickly gained a reputation as a stone of healing, protection, and self-transformation. It is believed to activate the throat, third-eye, and crown chakras, allowing wearers to enhance their psychic abilities and connect with higher dimensions. This association with spiritual growth has made tanzanite a popular choice among those seeking personal development and enlightenment.
Blue topaz, the final of December’s birthstones, has a more varied historical background. Its name comes from the Sanskrit word for fire, a nod to its fiery origins before being transformed into its more familiar blue hues through irradiation. Blue topaz is a modern addition to the December birthstone list, but it has quickly become a favorite among jewelers and collectors for its affordability, versatility, and vibrant color. Historically, it was considered a symbol of love and affection, and it is said to aid in improving one’s disposition and sweetness.
Together, these gemstones form a rich tapestry of December’s birthstone heritage, each contributing to the month’s unique identity. Whether through their ancient uses in Egypt and China, their spiritual associations in modern times, or their practical applications in jewelry, December’s birthstones reflect a deep and enduring connection between humanity and the natural world.
Geological Formation and Sources
The December birthstones are formed through a variety of geological processes, each contributing to the unique characteristics of the gemstones. Turquoise, for example, is a phosphate of aluminum and copper, formed through the interaction of water with phosphorus-rich rocks. This process typically occurs in arid environments, where the slow movement of water allows the minerals to crystallize over long periods. Turquoise is found in several countries, including the United States, Iran, China, and Egypt. In the United States, some of the most famous turquoise deposits are located in the southwestern states, such as Arizona, New Mexico, and Nevada. These regions are known for producing high-quality turquoise with vibrant blue and green hues, often enhanced by the presence of matrix patterns.
Zircon, another December birthstone, is a zirconium silicate that forms in igneous and metamorphic rocks. It is one of the oldest minerals on Earth, with some zircon crystals dating back over 4 billion years. This makes zircon not only a beautiful gemstone but also a valuable tool for geologists studying the Earth’s history. Zircon is found in various parts of the world, including Thailand, Cambodia, Vietnam, Nigeria, and Australia. The gemstone is often heat-treated to produce its popular blue and colorless varieties, as well as orange, yellow, and red. However, some heat-treated zircons may revert to their original colors after prolonged exposure to bright light, making it important to store these stones in a cool, dark place.
Tanzanite, the youngest of December’s birthstones, is a type of zoisite that was first discovered in 1967 in Tanzania. It is found exclusively in the Merelani Hills near Arusha, a region known for its unique geological conditions. Tanzanite is formed under high-pressure, low-temperature conditions, which contribute to its distinctive blue-violet color. The gemstone’s rarity and unique origin have made it highly sought after in the jewelry industry. Due to the limited supply of tanzanite, it is considered one of the most valuable and exclusive gemstones in the world.
Blue topaz, the final of December’s birthstones, is a silicate mineral composed of aluminum and fluorine. It is found in various parts of the world, including Brazil, Mexico, Nigeria, and the United States. Blue topaz is typically colorless in its natural state, but it is often irradiated to produce its popular blue hues. This process does not alter the gemstone’s chemical composition, making it safe and stable for use in jewelry. The resulting blue topaz is known for its glass-like luster and deep cleavage, which make it a favorite among jewelers and collectors.
These diverse geological origins and sources contribute to the unique properties and beauty of December’s birthstones. Whether formed through the slow movement of water in arid environments, the intense heat and pressure of geological processes, or the careful treatment of naturally occurring minerals, each December birthstone tells a story of the Earth’s history and the natural forces that shape our world.
Gemological Properties
The December birthstones are distinguished by their unique gemological properties, which contribute to their beauty, durability, and practicality in jewelry. Each gemstone has its own distinct characteristics, including color, hardness, clarity, and chemical composition.
Turquoise is a semi-translucent to opaque gemstone that ranges in color from blue to green, often with veins of matrix running through it. It has a hardness of 5 to 6 on the Mohs scale, which means it is relatively soft and prone to scratching. This makes turquoise best suited for jewelry that is worn infrequently, such as pendants or earrings. Turquoise also has a porosity that can make it susceptible to damage from moisture and chemicals, so it is important to store it in a cool, dry place and avoid exposing it to harsh cleaning agents.
Zircon, on the other hand, is a much harder gemstone, ranging from 6 to 7.5 on the Mohs scale. This hardness makes it more durable than turquoise, but it is still susceptible to abrasion and can be damaged if exposed to rough conditions. Zircon is often heat-treated to produce its popular blue and colorless varieties, as well as orange, yellow, and red. However, some heat-treated zircons may revert to their original colors after prolonged exposure to bright light, making it important to store these stones in a cool, dark place. Zircon is also generally stable when exposed to chemicals, making it a good choice for everyday wear.
Tanzanite is a relatively soft gemstone, with a hardness of 6 to 6.5 on the Mohs scale. This makes it prone to scratches and requires careful handling when worn in jewelry. Tanzanite is known for its deep blue-violet color, which is caused by the presence of vanadium. It is also pleochroic, meaning it can display different colors depending on the angle from which it is viewed. Tanzanite is typically cut in a way that maximizes its color and brilliance, making it a popular choice for rings, pendants, and earrings.
Blue topaz is a harder gemstone, with a hardness of 8 on the Mohs scale, making it one of the most durable of December’s birthstones. This hardness makes it well-suited for everyday wear, and it is often used in rings, bracelets, and necklaces. Blue topaz has a chemical formula of Al2SiO4(F,OH)4, with strong chemical bonding that makes it harder than most silicate minerals. It is also generally stable when exposed to light and chemicals, making it a versatile and practical choice for jewelry.
These diverse gemological properties make each of December’s birthstones suitable for different types of jewelry and wearing conditions. Whether choosing a soft and delicate turquoise for a special occasion or a hard and durable blue topaz for everyday wear, December-born individuals can find a gemstone that suits their lifestyle and personal preferences.

The December birthstones are not only admired for their beauty and durability but also for their rich symbolism and metaphysical properties. Each gemstone is associated with different meanings and powers, making them popular choices for those seeking protection, healing, and personal transformation.
Turquoise, one of the oldest and most revered December birthstones, has long been considered a symbol of protection and good fortune. In ancient Egypt, turquoise was believed to ward off evil and bring health and prosperity to the wearer. It was also used as a form of currency and was highly valued by pharaohs and other rulers. In Hindu tradition, turquoise was thought to break into pieces at the approach of disaster, serving as a warning to the wearer. It was also believed that seeing turquoise after beholding the new moon would ensure fantastic wealth. These beliefs have contributed to turquoise’s enduring popularity as a protective stone, making it a favorite among those seeking to enhance their well-being and fortune.
Zircon, with its ancient history and diverse color palette, is associated with a variety of metaphysical properties.

It is also thought to welcome visitors warmly and ensure peaceful sleep without nightmares. Zircon’s association with protection and healing has made it a popular choice for those seeking to enhance their physical and emotional well-being. Additionally, zircon is often used in spiritual practices to promote clarity and insight, making it a valuable tool for meditation and personal growth.
Tanzanite, a modern discovery with deep spiritual significance, is believed to activate the throat, third-eye, and crown chakras, allowing wearers to tap into their psychic abilities and communicate with higher dimensions. This association with spiritual growth has made tanzanite a popular choice among those seeking personal development and enlightenment. It is also believed to promote healing, protection, and self-transformation, making it a powerful stone for those undergoing significant life changes. These properties have contributed to tanzanite’s growing popularity in the metaphysical community, where it is often used in chakra balancing and energy work.
