Quick answer: Turquoise, December's traditional birthstone, is the sky-colored 'stone of protection' — a talisman of travelers, warriors, and fortune-seekers for over 5,000 years, now joined by zircon and tanzanite as modern December stones.

December is the only month with three birthstones — and the oldest of them, turquoise, is also the most storied. Long before birthstones were a jewelry-store convention, turquoise was a sacred material: mined by pharaohs, worn by Persian kings against the evil eye, inlaid into Aztec ritual masks, and revered by the peoples of the American Southwest as the stone of the sky. Its color — that unmistakable blue-green of desert skies and tropical shallows — has been carved, polished, and gifted as a token of protection for five millennia.

The name comes from the French pierre turquoise, "Turkish stone," because it reached Europe through Turkish trade routes from Persian mines. Chemically, turquoise is a hydrated copper-aluminum phosphate; copper gives it the blue, iron the green. And unlike most birthstones, turquoise is opaque — its beauty is in color, pattern, and history rather than sparkle. For December birthdays, it is a birthstone with soul: ancient, warm, and full of stories.

Turquoise Meaning and Symbolism

Across nearly every culture that touched it, turquoise symbolizes protection, good fortune, and honest expression. Ancient Egyptians — who mined turquoise at Serabit el-Khadim in the Sinai as early as 3000 BCE — believed it guarded against misfortune; King Tutankhamun was buried with turquoise inlaid into his famous gold funerary mask. In Persia, where the world's finest turquoise came from Nishapur, the stone was worn to ward off the evil eye, and a Persian proverb held that holding turquoise in hand brought its color's good fortune.

In the American Southwest, turquoise is profoundly sacred: Navajo, Zuni, and Pueblo traditions call it the stone of the sky, a bridge between heaven and earth, used in healing ceremonies, amulets, and trade for centuries. Tibetan traditions prize turquoise as a symbol of health and fortune, often set in protective amulets worn against illness. Medieval Europeans believed turquoise fell off its setting or changed color to warn the wearer of danger — an early "wellness ring." In the language of love, turquoise is the traditional gift for 11th wedding anniversaries, and modern crystal traditions associate it with the throat chakra: clear, honest communication and the courage to speak one's truth.

A Brief History of Turquoise

Turquoise is among humanity's oldest worked gemstones. The Sinai mines were worked under Egyptian pharaohs who sent entire expeditions — inscriptions there record Pharaohs' names carved into the rock alongside prayers. By the time of the Aztecs, turquoise was more precious than gold: the double-headed serpent mosaic pectoral in the British Museum, crafted for an Aztec ruler, uses hundreds of turquoise tiles — gold was abundant, but turquoise was divine.

Persian Nishapur turquoise — the famed "robin's egg blue" — supplied royal courts for a thousand years and set the standard for fine color. Spanish conquistadors carried Southwestern turquoise back to Europe, where it became a Victorian-era sensation after Napoleon's sister and later the British royal family wore it. In the 20th century, turquoise became the signature stone of Native American silver jewelry, and mines like Arizona's Sleeping Beauty — whose pure, matrix-free sky blue made it the world's most famous turquoise — supplied the bohemian jewelry boom of the 1960s and 70s. (Sleeping Beauty closed in 2012, making its stones increasingly prized.) Today, fine natural turquoise from old American mines commands collector prices, and the stone's 5,000-year reign as humanity's protector shows no sign of ending.

The Other December Birthstones: Zircon and Tanzanite

Turquoise has company. December's modern birthstones are zircon and tanzanite — two very different, very beautiful stones.

Zircon (not to be confused with cubic zirconia) is one of the oldest minerals on Earth — some Australian zircon crystals are 4.4 billion years old. It was believed in medieval times to induce sleep, ward off evil, and bring prosperity. Blue zircon, heat-treated from brown rough, is famous for its brilliance and fire that can rival diamond; it also comes in golden "hyacinth," green, and red. On the Mohs scale it ranks 7.5, making it reasonably durable for rings.

Tanzanite is the newcomer, discovered in Tanzania in 1967 and named by Tiffany & Co. Found in only one place on Earth — a small area near Mount Kilimanjaro — it displays pleochroism: shifting between velvety blue and violet depending on the angle of light. Fine tanzanite over five carats is increasingly scarce, and its single-source story makes it a collector favorite. All three December stones share the blue family, but each offers a completely different personality: turquoise the ancient protector, zircon the fiery traditionalist, tanzanite the modern marvel.

What Makes Fine Turquoise

Turquoise quality is judged differently from faceted gems — color is everything:

Color: The most prized color is an even, intense, medium sky blue — the legendary "robin's egg" or "Persian blue." Greenish tones are less valuable, though some collectors love them. Uneven, pale, or chalky color drops the price sharply.
Matrix: The dark veining of host rock (iron pyrite or limonite) running through turquoise is called matrix. Fine Persian and Sleeping Beauty turquoise has little to none, but dramatic "spiderweb" matrix from mines like Arizona's Number 8 is beloved in its own right — it is a matter of taste, not a flaw.
Hardness and treatment: Most commercial turquoise is stabilized (infused with resin to harden porous stone) — this is standard and accepted, but natural, untreated turquoise from old mines commands large premiums. Always ask whether a stone is natural, stabilized, or "reconstituted" (powder glued together — far less valuable). Chalky, untreated-but-soft turquoise can also be dyed to fake fine color.

The golden rule of turquoise buying: ask the mine name. Reputable sellers name the mine — Sleeping Beauty, Kingman, Bisbee, Royston, Morenci — because origin is turquoise's pedigree. Suspiciously cheap, perfectly uniform "turquoise" is almost always dyed howlite or magnesite.

Turquoise in Jewelry: Styles and Settings

Turquoise is traditionally cut as cabochons — smooth domes that show off color and matrix — and set in silver, its classic partner. The iconic Southwestern look pairs chunky turquoise with hand-worked sterling silver, and it remains timeless. Modern designers set turquoise in yellow gold for a warm, luxurious contrast, or in rose gold for a romantic pairing. Turquoise beads — rondelles, heishi, nuggets — make wonderful necklaces and bracelets, and inlay work (crushed turquoise set in channels of silver or gold) gives bold Southwestern style.

Because turquoise is relatively soft (5–6 on the Mohs scale), it suits rings with protective settings — bezels rather than high prongs — and is happiest in pendants, earrings, and bracelets, where it takes fewer knocks. For December birthstone jewelry, consider pairing turquoise with blue zircon or tanzanite accents for a tonal blue story, or keep it solo: turquoise has five thousand years of presence and needs no help.

Caring for Your Turquoise

Turquoise is porous and soft, so it needs gentler care than most birthstones. Remove turquoise jewelry before swimming, showering, cleaning, or applying lotion and perfume — chemicals and oils can permanently darken or green the stone (vintage turquoise often shows this "patina" from decades of wear). Clean with a soft, dry cloth only; never use ultrasonic cleaners, steam, or harsh chemicals. Store turquoise pieces separately so harder gems cannot scratch them. Treated and stabilized turquoise is more forgiving, but the rule stands: turquoise rewards gentle owners and remembers rough ones.

Is Turquoise Right for You?

Beyond December birthdays and 11th anniversaries, turquoise calls to anyone drawn to protection with personality. It is not a cold, glittering stone — it is warm, earthy, and alive with human history. Whether you choose a matrix-free Persian-blue cabochon, a wild spiderweb stone from an old Arizona mine, or a modern tanzanite alternative, you are wearing the oldest protective talisman in the jewelry box.

And if you are shopping for a December birthday, remember the deeper message the stone has carried since the pharaohs: may the sky watch over you. Few gifts carry a five-thousand-year blessing — turquoise does.

Frequently asked questions

What is December's birthstone?

December has three birthstones: turquoise (the traditional choice), zircon, and tanzanite. Turquoise is the most iconic — an opaque sky-blue stone used as a protective talisman for over 5,000 years across Egypt, Persia, Tibet, and the American Southwest.

What does turquoise symbolize?

Turquoise symbolizes protection, good fortune, honest communication, and healing. Ancient cultures believed it guarded travelers, warriors, and horses from harm; Persian traditions held it protected against the evil eye, and Native American traditions call it the stone of the sky.

How can you tell real turquoise from fake?

Real turquoise is waxy rather than glassy, often has natural matrix veining, and varies slightly in color across a stone. Fakes — dyed howlite, dyed magnesite, plastic, or reconstituted powder — look unnaturally uniform and vivid. Suspiciously cheap 'turquoise' in perfect sky-blue is almost always dyed howlite. Ask for the mine name and any stabilization disclosure.

Is turquoise fragile in jewelry?

Turquoise ranks only 5–6 on the Mohs scale, so it is softer than most gems and porous. It can absorb oils, perfumes, and chemicals, which change its color over time. Remove turquoise jewelry before swimming, cleaning, or applying lotion, and clean only with a soft dry or slightly damp cloth.

What are the other December birthstones?

Besides turquoise, December's modern birthstones are zircon and tanzanite. Zircon is one of the oldest minerals on Earth, known for brilliant fire and colors from blue to golden. Tanzanite, found only in Tanzania, is a velvety blue-violet stone discovered in 1967 and beloved for its pleochroic color shift.
