December has two birthstones: Zircon and tanzanite.

Zircon was believed to provide wisdom and honor

The name “zircon” comes from the Persian word zargun, meaning “gold-colored,” though this gem is found in a breathtaking array of hues. Revered since ancient times, zircon was treasured in the Middle Ages as a protective talisman believed to bring wisdom and honor. Today, the most sought-after variety for December is brilliant blue zircon, celebrated for its intense sparkle that rivals diamonds. Mined in Cambodia, Sri Lanka, and Australia, zircon is both durable and versatile, making it ideal for rings, earrings, bracelets, and pendants. Its radiant wintery glow pairs beautifully with any precious metal, offering a timeless elegance for holiday gifting.

Tanzanite is only found in one place

Tanzanite’s name comes from its sole place of origin—Tanzania—where it was discovered in 1967 near Mount Kilimanjaro. The gemstone’s mesmerizing blue-violet color, caused by trace amounts of vanadium, shifts under different lighting, adding to its allure. Often considered one of the most exciting gem discoveries of the 20th century, tanzanite is rarer than diamonds, as it is mined from just one small region in the world.
