December Birthstones Guide: Turquoise, Zircon, and Tanzanite

December’s birthstones offer a vibrant trio of gems that bring a welcome splash of color to the year's final month. While many months have only one dedicated gem, December boasts three distinct stones: Turquoise, Zircon, and Tanzanite. Each possesses a unique personality that provides a lively counterpoint to winter’s often subdued tones.

These gemstones offer more than just decoration; they embody deep history, cultural significance, and extraordinary flair. From the ancient, storied past of turquoise to the fiery brilliance of zircon and the relatively new discovery of tanzanite, the December birthstones invite us to embrace uniqueness. Below, we explore the history, styling, and care for these three spectacular blue gemstones.

Turquoise is arguably the most recognized of the December birthstones, serving as a cultural icon for thousands of years. Revered by ancient Egyptians, Persians, and Native American tribes, its opaque blue-green hue has long been a symbol of protection, healing, and tranquility.

While deeply rooted in history, turquoise is not confined to the past. Today, it remains a staple in fashion, appearing in everything from bohemian-inspired accessories to sophisticated high-jewelry designs.

For those exploring turquoise jewelry, it is helpful to look beyond traditional Southwestern silver styles. This gemstone creates a stunning statement in minimalist gold settings or as a vibrant centerpiece in bold, contemporary rings. Its earthy, organic appearance makes it a versatile choice for December birthdays, transitioning effortlessly from casual daywear to striking evening attire.

Zircon is a gem that refuses to be categorized. Often unfairly confused with cubic zirconia (a synthetic simulant), natural zircon is a historic mineral that offers a dazzling array of colors—from electric blues (the most popular December hue) to fiery oranges, warm yellows, and deep reds.

The defining characteristic of zircon is its refractive index. It plays with light in a way few other gemstones can, creating a dynamic sparkle that rivals even diamonds. This optical property makes it the perfect December birthstone for those who love brilliance and fire.

Whether you seek a bold, colorful cocktail ring or a subtle, elegant pendant, zircon offers the versatility to fit any aesthetic. It thrives on variety, making it an ideal gem for celebrating individuality.

Discovered in Tanzania in the 1960s, Tanzanite is the newcomer to the gemstone world. Despite its recent addition to the birthstone list, it has quickly cemented its status as a modern classic. Its striking blue-violet hues—often displaying pleochroism, where the stone shows different colors depending on the angle—are unlike anything else in the mineral kingdom.

Tanzanite is the rarest of the December birthstones, found only in the Merelani Hills of Tanzania. This exclusivity makes it a "modern marvel" and a highly sought-after gem for collectors.

Ideal for those who appreciate the extraordinary, tanzanite’s vivid presence commands attention. Whether set in a classic diamond halo ring or a contemporary necklace, it is a gemstone that speaks to sophistication and modern elegance.

Turquoise has proven its versatility time and again, moving far beyond the "boho-chic" label. Modern designers are reimagining this December birthstone by setting it in sleek, minimalist pieces that let the stone's natural matrix and color take center stage.

Current trends favor geometric shapes, mixed metals, and unexpected pairings—such as turquoise set with diamonds or pearls.

• Stacking: Consider stacking simple turquoise bands with yellow gold or platinum rings.

• Minimalism: Pair a solitaire turquoise pendant with a clean, understated chain.

• Contrast: The juxtaposition of turquoise’s opaque bold color against the sparkle of transparent gems creates a look that is both fresh and timeless.

Because December has three birthstones with different physical properties, each requires specific care to maintain its beauty.

• Turquoise Care: Turquoise is a porous stone (5-6 on the Mohs scale). It is sensitive to chemicals, perfumes, and extreme temperatures. To prevent discoloration, avoid ultrasonic cleaners and exposure to harsh household cleaning agents.
• Zircon Care: While Zircon is harder (6-7.5 on the Mohs scale), its facet edges can be brittle. It is best to store zircon jewelry separately in a soft pouch to avoid chipping or scratching from harder stones like diamonds or sapphires.
• Tanzanite Care: Tanzanite is relatively soft (6-7 on the Mohs scale) and has distinct cleavage, meaning it can split if struck. Clean it gently with warm, soapy water and a soft brush. Avoid ultrasonic or steam cleaners.

Regular maintenance and professional checks are recommended for all three gems to ensure prongs remain tight and stones remain brilliant.

The three December birthstones—Turquoise, Zircon, and Tanzanite—are more than just vibrant jewelry choices; they are symbols of personal style.

• Turquoise for the history lover and the grounded spirit.

• Zircon for the vibrant personality who loves sparkle.

• Tanzanite for the connoisseur of rare and modern beauty.
