The month of December, characterized by its crisp air and the quietude of winter, is unique in the world of gemology for being represented by a trio of breathtaking blue gemstones. For those born in this transitional month, the question of what is december birthstone reveals a lineage of minerals—Turquoise, Zircon, and Tanzanite—that span across cultures, continents, and millennia.
At PureJewels, we view these stones not merely as decorative elements but as vessels of history and artisanal excellence. Each stone offers a different shade of the celestial sky, from the earthy robin’s-egg blue of Turquoise to the deep, hypnotic violet-blue of Tanzanite. These stones have adorned the regal necks of Pharaohs and the sophisticated modern collections of today’s connoisseurs.
Choosing a birthstone is a deeply personal journey. Whether you are seeking a bespoke piece to celebrate a milestone or exploring heirloom quality gifts for a loved one, understanding the provenance and symbolism of December’s treasures is the first step in finding a piece that resonates with your soul.
Key Takeaways
- Multiple Identities: December is one of the few months with three official birthstones: Turquoise, Zircon, and Tanzanite.
- Ancestral Heritage: Turquoise is one of the oldest gemstones used in karigari and jewellery making, dating back to ancient Egypt and Persia.
- Modern Rarity: Tanzanite is a 20th-century discovery, found only in a small area at the foothills of Mount Kilimanjaro, making it 1,000 times rarer than diamonds.
- Optical Brilliance: Zircon (not to be confused with synthetic cubic zirconia) is a natural gemstone renowned for its “fire” and high refractive index.
- Symbolism: These stones are traditionally believed to bring devotion, protection, and prosperity to the wearer.
- Investment Value: High-grade Zircon and Tanzanite are considered collectible assets due to their limited geographic origins and exceptional quality.
Defining the December Birthstones
In the most technical sense, the December birthstone refers to a curated group of blue gemstones officially recognized by the American Gem Trade Association and the Jewelers of America. While Turquoise was the original standard, Zircon and Tanzanite were added to the calendar to offer diversity in hue and brilliance.
A quick summary of their characteristics:
- Turquoise: An opaque, phosphate mineral known for its distinctive blue-to-green palette and historical provenance.
- Zircon: A brilliant silicate mineral that occurs in many colors, though the vivid “Starlight” blue is the preferred choice for December.
- Tanzanite: A blue-violet variety of the mineral zoisite, prized for its pleochroism—the ability to show different colors when viewed from different angles.
| Feature | Turquoise | Zircon | Tanzanite |
|---|---|---|---|
| Luster | Waxy to Dull | Adamantine (Diamond-like) | Vitreous (Glass-like) |
| Hardness (Mohs) | 5.0 to 6.0 | 7.5 | 6.5 to 7.0 |
| Color Range | Sky Blue to Teal | Electric Blue to Honey | Ultramarine to Violet-Blue |
| Transparency | Opaque | Transparent | Transparent |
The Soul of Turquoise: A Legacy of Protection
Turquoise is a stone that bridges the gap between the terrestrial and the divine. In the world of heritage craftsmanship, it has been a staple for thousands of years. From the turquoise-inlaid masks of the Aztecs to the karigari traditions of the East, this stone is synonymous with timeless elegance.
We often find that clients are drawn to Turquoise for its matte finish and organic feel. It does not demand attention through sparkle; rather, it commands respect through its rich, saturated color and the story of the earth written in its “matrix”—the dark veins of host rock that sometimes spiderweb across the surface.
For those seeking a meaningful gift, Turquoise represents health, wealth, and a ward against negative energy. It is an ideal choice for kids jewellery or daily staples like stud earrings, where the stone’s vibrant hue can brighten the face without being overly ostentatious.
The History of Persian Turquoise
The finest Turquoise has historically come from the Nishapur district of Iran, often referred to as “Persian Turquoise.” These specimens are prized for being “clean”—meaning they lack the dark matrix found in many North American varieties. This pure, robin’s-egg blue has been a mainstay in royal legacy collections for centuries.
In our experience, the use of Turquoise in 22ct gold jewellery creates a striking contrast. Use of high-purity gold enhances the warmth of the stone, making it a favorite for festive gifts and cultural storytelling pieces that honor traditional aesthetics while remaining refined for a contemporary audience.
The Brilliance of Blue Zircon: Nature’s Hidden Fire
There is a common misconception that Zircon is a synthetic material. At PureJewels, we take pride in educating our patrons on the exceptional quality of natural Zircon. It is, in fact, the oldest mineral on Earth, with some crystals dating back over 4 billion years.
Zircon possesses a “fire” that rivals that of a diamond. This is due to its high double refraction, which causes light to split into two rays as it passes through the stone. This creates a mesmerizing depth and a lively dance of light that makes it a perfect centerpiece for an personalised ring.
The “Starlight” Blue
While Zircon appears in many shades, the blue variety is traditionally achieved through careful heat treatment of reddish-brown Zircon found primarily in Southeast Asia. This process, a masterclass in metallurgical expertise and thermal craftsmanship, produces a shade of blue that is unlike any other in the gemstone kingdom—bright, energetic, and deeply translucent.
When selecting a Zircon, consider its setting carefully. Because Zircon can be slightly brittle at its facet edges, we often recommend protective settings such as bezels or masterfully crafted prongs that ensure the stone’s longevity as an enduring family heirloom.
Tanzanite: The Rarity of a Single Source
Tanzanite is a relatively new addition to the December family, having been discovered in 1967. Found only in a four-kilometer strip of land in Tanzania, its provenance is so singular that experts believe the world’s supply may be exhausted within a single generation.
This rarity imbues Tanzanite with an air of luxury and exclusivity. It is the gemstone for the woman or man who celebrates their own unique journey. Its color—an exquisite blend of royal blue and deep violet—shifts as you move, revealing flashes of red or burgundy in higher-grade specimens.
A Statement of Sophistication
Tanzanite is best suited for evening wear and special occasions. We often incorporate this stone into drop earrings or a personalised necklace to allow the stone to capture the light. Its luxurious depth makes it a standout choice for anniversary gifts or a treat for oneself after a significant personal achievement.
Owning a Tanzanite is a commitment to the preservation of traditional skills. Because the stone is pleochroic, the lapidary (the artisan who cuts the stone) must possess design intelligence to determine which axis will yield the most vibrant blue. A single misstep can result in a paler, less valuable stone.
Choosing Your December Gemstone: A Guide to Purpose
Selecting what is december birthstone for your collection depends largely on your lifestyle, aesthetic preference, and the narrative you wish to convey. At PureJewels, we believe that every meticulously crafted piece should reflect the wearer’s identity.
For Daily Wear and Cultural Connection
If you value artisanal texture and a connection to ancient civilizations, Turquoise is your stone. Its durability (when handled with care) and opaque beauty make it a versatile companion for both casual and refined attire. Consider Turquoise for personalised pendant designs that sit close to the heart.
For Unmatched Sparkle and Brilliance
For those who love the “fire” of a diamond but desire a dash of celestial color, Blue Zircon is the iconic choice. It offers a luxury look with a unique optical signature that is sure to spark conversation. This stone is particularly effective in high-karat gold, where the yellow tones of the metal accentuate the electric blue of the Zircon.
For the Collector and the Visionary
Tanzanite is for the individual who understands the value of provenance and rarity. As a collectible gemstone, it represents a moment in geologic history that can never be repeated. It is a stone of devotion and deep emotional resonance, making it an exceptional choice for wedding gifts.
The Craftsmanship Behind the Stone
At PureJewels, the journey of a gemstone from the earth to your curated collection is one of immense integrity and trust. We work closely with master artisans who understand the soul of these materials. Whether it is the traditional goldsmithing techniques used in our 22ct collections or the precise engineering of our platinum settings, we prioritize artisanal excellence.
Our karigari—the art of Indian craftsmanship—is particularly suited to the vibrant blue of December’s stones. The use of intricate filigree, granulation, and hand-hallmarked metals ensures that the final piece is not just jewellery, but a work of wearable art.
The Significance of Hallmarked Quality
When investing in luxury with purpose, exceptional materials must be matched by certified purity. Every piece of 22ct gold jewellery we provide is hallmarked in the UK, ensuring that your legacy is built on a foundation of integrity. This is especially important for generational pieces like a gold spoon for a newborn or a personalised bracelet for a graduation.
Caring for Your December Treasures
Each of the three December birthstones requires specific care to maintain its timeless elegance and enduring luster. As your trusted consultative jeweler, we recommend the following masterfully tested practices:
- Turquoise: Being porous, Turquoise should be kept away from perfumes, oils, and harsh chemicals. Simply wipe it with a soft, dry cloth after wearing.
- Tanzanite: Avoid ultrasonic cleaners. This stone is sensitive to thermal shock and should be cleaned with mild soap and lukewarm water.
- Zircon: While durable, Zircon should be stored separately to prevent the facets from scratching other stones or being scratched by harder gems like diamonds.
Investment and Gifting: A Celebration of Moments
Whether you are browsing our jewellery under 550 or commissioning a bespoke masterpiece, a December birthstone is a profound way to celebrate a journey. These stones are popular choices for birthday gifts, christmas gifts, and even anniversary gifts marks of devotion.
For men, the deep hues of Zircon or Tanzanite in mens jewellery, such as signet rings or lapel pins, offer a sophisticated alternative to traditional metals. For children, a simple initial pendant set with a small Turquoise can serve as a first introduction to the world of fine gemstones.
Frequently Asked Questions
Which December birthstone is the “true” one?
There is no single “true” birthstone. Traditionally, Turquoise is the most ancient, while Zircon and Tanzanite were added to the official list to provide more choices in terms of color intensity and brilliance. All three are authentic representations of December.
Is blue the only color for December birthstones?
While all three are prized for their blue hues, Zircon actually naturally occurs in green, red, yellow, and brown. However, the vivid blue remains the symbolic standard for those born in December.
How can I tell if my Turquoise is real?
Genuine Turquoise should have a cool, stony feel and a weight that feels substantial. At PureJewels, we emphasize provenance and integrity, sourcing only authentic, natural stones that meet our high standards for exceptional quality.
Is Tanzanite a good investment?
Tanzanite is often considered a collectible gemstone because it is found in only one location on Earth. As the mines reach the end of their lifespan, the scarcity of high-quality Tanzanite is expected to increase its heirloom value.
Can I wear Zircon every day?
Yes, Zircon is relatively hard (7.5 on the Mohs scale), making it suitable for daily wear. However, we recommend a refined setting that protects the edges of the stone, such as those found in our masterfully crafted rings.
What is the spiritual meaning of Turquoise?
For centuries, Turquoise has been a symbol of devotion, friendship, and protection. Many cultures believe it acts as a bridge between the sky and the sea, bringing peace and tranquility to the wearer.
The journey to find the perfect December birthstone is one of discovery. We invite you to explore our curated collections, where heritage craftsmanship meets modern luxury. Whether it is the earthy appeal of Turquoise or the celestial fire of Zircon, your choice will become a cherished part of your family’s legacy.
