December’s birthstones, explained

Swiss Blue Topaz, Zircon

December has four modern birthstones: blue topaz, blue zircon, tanzanite, and turquoise. We handcraft two of them. Swiss blue topaz rates 8 on the Mohs hardness scale, and natural blue zircon rates 7 with near-diamond fire.

Meaning and Properties

Blue topaz has long been tied to calm and clear communication. Zircon is the oldest mineral on Earth, with crystals dating back over four billion years, and has symbolized wisdom and prosperity since the Middle Ages.

Chakra and Energy

December’s blues are associated with the throat chakra, the energy center tied to calm, honest expression. They are believed to steady the mind and support clear words.

December Birthstones and Zodiac

December spans two zodiac signs: Sagittarius (November 22 to December 21) and Capricorn (December 22 to January 19). Blue topaz is the primary Sagittarius birthstone, and zircon is recognized for both signs. Explore our zodiac jewelry collection.

December Birthstone Jewelry

December has four official birthstones: blue topaz, tanzanite, turquoise, and zircon. Zircon is a natural gemstone (not cubic zirconia) with more fire than diamond and crystals dating back 4.4 billion years. Swiss blue topaz offers a bright, vivid blue at an excellent price point. At Erin Gallagher Jewelry, our December collection features both zircon and Swiss blue topaz pieces, all handcrafted in Colorado.

Zircon

Swiss Blue Topaz

Zircon vs. Swiss Blue Topaz

Zircon (Mohs 6.5 to 7.5) has exceptional fire and brilliance but can be brittle at the edges. Swiss blue topaz (Mohs 8) is harder and more durable for everyday wear. Both are beautiful December birthstones. Learn more about zircon or Swiss blue topaz meaning and properties.
