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 has four official birthstones: blue topaz, tanzanite, turquoise, and zircon. At Erin Gallagher Jewelry, we carry two: zircon (a natural gemstone with more fire than diamond, Mohs 6.5 to 7.5) and Swiss blue topaz (Mohs 8), both handcrafted in Colorado from $20.
No. Zircon is a natural gemstone — a zirconium silicate mineral (ZrSiO4) with crystals dating back 4.4 billion years and more fire than diamond. Cubic zirconia is a synthetic material with no connection to natural zircon. Blue zircon achieves its color through heat treatment, which is permanent. Read our full guide: Zircon vs. Cubic Zirconia.
Swiss blue topaz (Mohs 8) is harder than zircon (Mohs 6.5 to 7.5) and better suited for everyday rings and bracelets. Zircon is more brittle and best protected in bezel settings; it is ideal for earrings and necklaces. Both are genuine gemstones available at Erin Gallagher Jewelry from $20.
Zircon is a natural zirconium silicate mineral (Mohs 6.5 to 7.5) valued for its exceptional fire and brilliance. Swiss blue topaz is a variety of topaz (Mohs 8) whose vivid medium blue color is achieved through irradiation and heat treatment, both permanent. Zircon has more sparkle; Swiss blue topaz is more durable for daily wear.
Zircon is the traditional gift for the 11th wedding anniversary. Swiss blue topaz (blue topaz) is the traditional gift for the 4th anniversary. Both make strong December birthday gifts for Sagittarius (November 22 to December 21) and Capricorn (December 22 to January 19).
