Each of these stones offers something special, from ancient cultural symbolism to breathtaking hues. Whether you're a curious rockhound, shopping for a meaningful gift, or just wondering what is the birthstone for December, this guide will take you through it all in a fun, simple, and educational way.
Let's explore these December stone birthstones and discover what makes them sparkle—literally and figuratively.
Why December Has Four Birthstones
Before diving into the stones themselves, let's answer a common question: why does December have four birthstones? Most months traditionally had only one, but over time, as gemstone markets expanded and consumer demand grew, multiple stones were added to offer variety in terms of availability, color, and cost.
The official birthstones for the month of December include:
- Turquoise - one of the oldest known birthstones
- Zircon - a gem with incredible sparkle that's often mistaken for diamond
- Tanzanite - a relatively new discovery in the gem world
- Blue Topaz - a popular modern option with a dazzling blue color
Each stone captures a different facet of December's chill beauty. From icy blue to deep violet to greenish sky-blue, the December birthstone colors are absolutely mesmerizing.
