Turquoise: The Timeless Sky-Blue Gem
When you picture December’s birthstone, that captivating, sky-blue color of turquoise is probably what comes to mind. It’s more than just a pretty stone—it's a piece of history, cherished by cultures across the globe for thousands of years as a symbol of wisdom, nobility, and protection.
Its legacy is truly ancient. Turquoise has a history stretching back over 6,000 years, making it one of the very first gems ever set into jewelry. Archaeologists have found intricate turquoise pieces in the tombs of Egyptian pharaohs, including the stunning inlays on King Tutankhamun’s famous burial mask.

Beyond its rich past, the stone’s color tells a fascinating story of its own.
The Science Behind Its Signature Color
The iconic blue of turquoise isn't just one shade but a beautiful spectrum. The final hue all comes down to the trace minerals present while the stone was forming, making each one unique. Think of it like nature mixing colors on a palette.
Copper Content: The presence of copper is what gives turquoise its prized, vibrant robin's egg blue. The more copper, the more intense the blue.
Iron Content: When iron gets into the mix, it lends the stone a greener tint, creating shades that range from soft seafoam to deep olive.
The most sought-after turquoise color is an even, intense, medium blue, often called "Persian blue" or "robin's egg blue." This pure hue is rare and highly valued by collectors and jewelry lovers alike.
Appreciating the Unique Matrix
Adding to its personality is the matrix—the intricate, web-like pattern of dark veins that often runs through the stone. These are remnants of the host rock where the turquoise formed, like a natural fingerprint. The matrix can be anything from a delicate spiderweb pattern to bold, dark splotches.
This characteristic means no two turquoise stones are ever exactly alike. Whether you prefer a pure, sky-blue stone or one with a dramatic matrix, you're choosing a gem with one-of-a-kind character, connecting you to an ancient story of beauty and fortune.
Discovering Tanzanite and Zircon's Brilliance
While turquoise holds the historic crown for December, two other incredible gems round out the modern birthstone trio: tanzanite and zircon. They bring a completely different kind of fire and color story to the table, giving December babies some seriously brilliant options.
First up is tanzanite, a geological newcomer with a violet-blue glow that’s almost otherworldly. It was only discovered in 1967 in the Mererani Hills of Tanzania—and to this day, that’s the only place on Earth you can find it. This makes it a true collector’s prize and 1,000 times rarer than diamonds.
The Magic of Tanzanite and Zircon
One of tanzanite’s most mesmerizing qualities is its pleochroism. This is a fancy way of saying it shows different colors when you view it from different angles. One moment it’s a deep sapphire blue, the next a rich violet, and then it might flash a hint of burgundy. It’s like holding a tiny, frozen sunset that dances with the light.
Tanzanite officially joined the birthstone list in 2002, bringing its signature velvety blues and purples to the December palette. It was a modern addition for a modern stone.
Then there’s zircon, a natural gemstone that often gets mistaken for its synthetic look-alike, cubic zirconia. But make no mistake, zircon is a magnificent mineral in its own right, beloved for centuries for its incredible fire and brilliance that can honestly give a diamond a run for its money.
Zircon comes in a surprisingly wide range of colors. Exploring the definitive A-Z list of gemstones for jewelry reveals just how versatile it is. While a stunning ice-blue is its claim to fame for December, you can also find it in warm, earthy reds, yellows, and even a completely colorless form that was once a popular diamond alternative.
These two gems have carved out their own space in the December birthstone market. Zircon's diamond-like sparkle accounts for about 15% of December sales, while tanzanite’s extreme rarity has it commanding prices from $500 to $1,200 per carat, making it a beautiful investment.

How to Choose Your Perfect December Gemstone
With three completely different stones sharing the December spotlight, picking the right one is all about you—your style, your budget, and how you live your life. It’s a fun journey into that beautiful winter blue palette, and each gem tells a totally different story.
Think about the jewelry you already reach for every day. Are you drawn to earthy, one-of-a-kind pieces? The bold blue-green of a turquoise cuff, with its organic web of matrix, might feel like it was made for you.
If you’re all about refined elegance, the rare, violet-blue glow of a tanzanite pendant adds a touch of quiet luxury. And for a classic look that never fails? The fiery sparkle of zircon studs delivers timeless brilliance, every single time.
Matching a Gem to Your Lifestyle
Looks are one thing, but practicality is everything. Your day-to-day life plays a huge role in which stone will be the best long-term fit, since they all have different levels of durability.
For Everyday Wear: Zircon is the toughest of the trio. Its resilience makes it a great candidate for rings or bracelets you plan on wearing often.
For Occasional Statements: The softer nature of turquoise and tanzanite means they're better suited for special occasions. They’re absolutely stunning but need a bit more care to avoid scratches.
And if you're shopping for a gift, exploring other luxury gift ideas for her, including timeless jewelry can spark even more inspiration for that perfect, memorable piece.
Sometimes, a simple visual makes the choice even clearer. This decision tree boils it down to two key factors: rarity and brilliance.
As you can see, if you want something truly rare, tanzanite is in a class of its own. If not, the choice between zircon and turquoise really comes down to whether you prefer brilliant sparkle or unique, earthy character.
By balancing your personal style, how you’ll wear it, and what feels right, you can confidently pick the gem that feels like a true reflection of you.
Styling Your December Birthstone Jewelry
Alright, you've found the perfect gem. Now for the fun part: making it yours. Styling is what turns a beautiful stone into a signature piece that feels like an extension of you, and December's birthstone colors are incredibly versatile.
The metal you choose is like the frame for a piece of art—it can completely change the mood. A great pairing doesn't just hold the stone; it elevates it.
Warm Metals (Yellow Gold, Rose Gold): These metals create a beautiful, warm contrast against the cool tones of turquoise, tanzanite, and zircon. Yellow gold makes turquoise feel earthy and bohemian, while rose gold gives blue zircon a soft, almost romantic glow.
Cool Metals (Silver, Platinum, White Gold): If you're going for a more seamless, elegant look, cool metals are your best friend. They create a harmonious vibe, letting the gemstone's color do all the talking. Think of tanzanite's deep, velvety blue set in platinum—it’s pure modern sophistication.
The real secret is matching the metal to the vibe you want. Warm metals often lean classic or even a little casual, while cool metals give off a sleek, contemporary feel.
Creating Looks for Every Occasion
Styling is all about context. A bold, chunky ring that's a showstopper on a night out might not fit in at the office. But the beauty of December's color palette is how easily it adapts.
For everyday wear, think delicate and layered. A fine chain with a tiny, brilliant zircon or a simple tanzanite charm adds just the right amount of sparkle without being overpowering. It's a modern, effortless look you can live in.
Casual vs Formal Styling Tips
For casual, daytime looks, don't be afraid to let turquoise be the star. A statement ring or a beaded bracelet looks fantastic with denim and neutral fabrics, adding a much-needed pop of vibrant color.
When it's time to dress up for a formal event or head to the office, lean into refined elegance. You can't go wrong with a pair of tanzanite stud earrings or a timeless zircon tennis bracelet. And for the men, a pair of subtle tanzanite cufflinks can add a personal, distinguished touch of color to a suit.
Keeping Your December Gems Sparkling
Protecting your jewelry is non-negotiable, and when it comes to December’s birthstones, each one has its own personality. You can't treat them all the same—what keeps a zircon brilliant might damage a piece of turquoise. Think of it as learning their individual love languages.
Take turquoise, for example. It's a relatively soft and porous stone, which means it acts a bit like a sponge. It can absorb liquids, lotions, and oils, which can slowly dull its iconic blue-green hue. My best advice? Always take off your turquoise rings and bracelets before putting on hand cream or perfume.
Tanzanite is tougher than turquoise, but it still needs a gentle touch. It’s particularly sensitive to sudden temperature shifts and sharp knocks, both of which can lead to cracks. For that reason, I always tell clients that tanzanite is more of a special occasion gem—perfect for a night out, but maybe not for everyday wear and tear.
Simple Care for Lasting Beauty
Even though they're all different, a few universal rules will keep your December birthstones looking their best.
Gentle Cleaning Only: For turquoise, a quick wipe-down with a soft, damp cloth is usually all you need. For tanzanite and zircon, you can use a little warm, soapy water and a very soft brush to get them sparkling again.
Store Them Separately: This is a big one. To prevent scratches, keep each piece in its own soft pouch or a lined jewelry box. While zircon is hard, it can be brittle, and this simple step will keep it from chipping against other, tougher gems.
No Harsh Chemicals, Ever: Never, ever use ultrasonic cleaners or harsh jewelry dips on turquoise or tanzanite. They are far too delicate for that kind of treatment.

Your December Birthstone Questions, Answered
Choosing a gemstone can bring up a lot of questions. To help you pick the perfect piece with total confidence, let’s clear up a few of the most common queries about December’s incredible birthstones.
What Is the Main December Birthstone Color?
Traditionally, the December birthstone color is that iconic, dreamy sky-blue of turquoise—a shade that’s been loved for centuries.
But the modern list opens up the palette in a big way. Now, you also have the deep, velvety violet-blue of tanzanite and the entire rainbow of zircon. While zircon is most famous for its brilliant blue, it also comes in stunning reds, yellows, and even colorless varieties that rival diamonds.
Which Gem Is Best for an Engagement Ring?
If you’re looking for a ring you can wear every day, zircon is definitely the most durable of the three. It scores a 6 to 7.5 on the hardness scale, meaning it’s much better at resisting scratches.
That said, even zircon can be a bit brittle and might chip if it takes a hard knock. Tanzanite (6.5 hardness) and turquoise (5-6 hardness) are significantly softer, so they aren't usually recommended for a daily-wear ring since they can scratch or damage easily.
Is Blue Zircon the Same as Cubic Zirconia?
Not at all—they’re completely different materials. Blue zircon is a natural, genuine gemstone that’s mined from the earth and valued for its incredible brilliance and fire.
On the other hand, cubic zirconia (or CZ) is a synthetic, lab-created stone made to look like a diamond. While CZ is a great affordable alternative, natural zircon is a historic and valuable gemstone in its own right.
