What Is December's Birthstone? Blue Topaz, Tanzanite & Turquoise

December has three birthstones: blue topaz, tanzanite, and turquoise. Blue topaz — with its clear, winter-sky blue — is the most popular and versatile choice, available in shades from light sky blue to deep London blue, and durable enough for everyday wear. Here's a closer look at December's trio.

Blue Topaz: December's Standout

If you're looking for the perfect December birthstone, blue topaz is the classic choice. Its captivating blue, reminiscent of a clear winter sky, makes it a favourite for jewellery — whether a ring, necklace, or earrings, it adds elegance to any outfit. At Irosk, our blue topaz is set in bright 925 sterling silver.

Why Blue Topaz?

Beyond its beauty, blue topaz is traditionally associated with calm, balance, and clear communication — meanings that are part of gemstone folklore rather than proven fact, but a lovely part of the stone's charm. It's also wonderfully versatile, coming in shades from light, airy Sky Blue Topaz to rich, deep London Blue Topaz, so you can pick the hue that suits your style.

Durable Enough for Everyday

Blue topaz is also durable, which makes it ideal for everyday wear. Whether you want an elegant statement piece or something subtle for daily use, it holds its vibrant shine over time with gentle care.

December's Other Birthstones: Tanzanite & Turquoise

While blue topaz takes centre stage, December babies also have tanzanite and turquoise to choose from:

• Tanzanite: known for its striking blue-violet colour, tanzanite is a relatively rare gem that's grown popular in recent decades, traditionally associated with transformation and self-discovery. Explore our tanzanite collection.
• Turquoise: with its distinctive blue-green hue, turquoise has been prized for centuries and is traditionally linked with protection and good fortune. Its rustic charm offers a different look to the classic elegance of blue topaz.

Why Blue Topaz Makes a Perfect Gift

For a December birthday, blue topaz is an easy winner. Its vibrant colour and timeless elegance suit a wide range of styles — a blue topaz necklace, a pair of stud earrings, or a delicate ring. It's also wonderfully affordable, offering a luxurious, high-quality look at a friendly price.
