All About Colored Stones: Blue Topaz, Winter’s Crisp Sparkle

As the chill of December approaches, blue topaz shines as a gemstone that mirrors winter’s icy elegance. Known for its stunning blue hues, blue topaz is considered to be one of December’s birthstones by many – joined by turquoise, tanzanite and zircon – bringing a crisp sparkle to jewelry and symbolizing love, loyalty, and clarity. Adored for centuries, this gem continues to captivate with its radiance and depth, adding a touch of winter wonder to anyone born in December – or anyone else enchanted by its cool, refreshing beauty.

Formation and Properties

Topaz forms deep underground in igneous rocks like granite and rhyolite, where fluorine and aluminum-rich fluids interact over millions of years, creating this beautiful crystal. It’s made primarily of aluminum and silicon, and while pure topaz is colorless, the blue variety we love requires a bit of extra work. Natural blue topaz is quite rare; most blue topaz on the market is color-enhanced through heat and irradiation. With a Mohs hardness of 8, it’s sturdy enough for daily wear, making it a practical and stunning choice for jewelry.

Appearance and Colors

Blue topaz comes in various shades, each with a unique name and charm:

  • Sky Blue: A light, airy blue that resembles a clear, sunny day.
  • Swiss Blue: A more vivid blue that borders on electric, perfect for those who like a little pop of color.
  • London Blue: The deepest of the blues, almost like the ocean at twilight, making it mysterious, alluring and the most valuable.


These shades, ranging from light to deep blue, are created through a special treatment process. Regardless of the shade, blue topaz has a dazzling clarity and luster that’s hard to miss.
The cut of the Blue Topaz also plays a significant role in its appearance. The brilliance of the stone is brought out by a well-executed cut. The most common cuts are round, oval, and cushion, but it can also be found in more unique cuts like heart and pear shapes.

History, Myths, and Legends

Blue topaz has a rich history, enjoying legendary status in ancient Egypt, the Roman Empire, India and beyond. The Romans associated the gemstone with Jupiter, their king of the gods. In historic Indian belief systems, topaz is said to help one’s intellect and emotions align with the universe, leading to a more enlightened existence. Another myth holds that blue topaz, particularly, was favored by water nymphs and sea gods, giving it an enchanting aquatic legacy. As a result, seafarers believed that wearing blue topaz would protect them from harm and ensure a safe return from sea voyages, much like aquamarine, a slightly softer blue/green gemstone from the Beryl family.

Countries of Origin

While natural blue topaz is rare, Brazil is famous for its quality topaz deposits, producing several colors, including blue. Other sources include the United States – particularly Texas – Mexico, Nigeria, and Russia. Each region’s topaz has its unique characteristics, often related to the intensity of the color and clarity.
