Blue Topaz and Tanzanite – December Birthstones

It’s time for another deep dive on this month’s birthstones. For December, we have gorgeous blue topaz and tanzanite taking on rich shades of blue for all our December babies. Read on to find out more about these sparkling stones and shop our favorite December birthstones.

Blue Topaz

Blue topaz gets its name from the word “topazion,” which may be related to the Egyptian island of Topazos. In the times of the ancient Greeks and Romans, the stone was valued greatly for its uniqueness and general rarity, though large deposits of the stone were eventually found in Brazil. Nowadays, topaz is very popular and accessible.

Originally, it was thought that all yellow gemstones were topaz, but it was soon discovered that topaz varies in color from yellow to blue and green to completely colorless. Blue topaz can sometimes resemble aquamarine, with a slightly deeper color that is sometimes heat-treated to enhance its appearance.

Did you know?

Topaz means “heat” in Hindu mythology. In fact, topaz was considered one of the “sacred stones” of the Kalpa tree, making it a holy stone for the Hindus. It was often worn as a pendant and believed to relieve thirst, extend one’s lifespan and increase intelligence.

Spiritual properties

Blue topaz is believed to stimulate the self-confidence of wearers, inspire creativity and increase attention span. It helps one to better articulate their thoughts and feelings and open lines of communication. A stone of peacefulness, blue topaz is thought to calm the emotions and is often used to aide meditation and spiritual readings.

Did you know?

It’s been suggested that the word “topaz” also comes from the Sanskrit word “tapas,” meaning fire, because blue topaz was believed to have cooling properties. In ancient civilizations, it was believed that when thrown into boiling water, the stone could actually cool the pot down.

Unlike many of our favorite gems, tanzanite is actually a relatively recent discovery. Tiffany & Co. named this brilliant blue gemstone after Tanzania, the first (and only) location where it was found in 1967. It is also known as “blue zoisite.” Since its discovery, it has become one of the most popular blue gemstones on the market.

Tanzanite has the unique property of being pleochroic, meaning it appears differently colored depending on how it is cut. It ranges from a deep blue to a more purplish tint. Its color is caused by small amounts of vanadium within its mineral structure. Tanzanite’s purple tone makes it stand out, particularly among other varieties of blue stones.

Did you know?

Tanzanite’s popularity grew in large part due to a public education campaign funded by Tiffany & Co. They developed and promoted educational materials to help jewelers understand, market and explain the characteristics of tanzanite to new customers.

Spiritual properties

Tanzanite is believed to have a high vibrational energy that envelops its wearers in protection and safety. Like blue topaz, it promotes good lines of communication while soothing and calming. It is also thought to bring a sense of self-awakening to those who wear it, encouraging psychic abilities and powers.

Did you know?

Popular legends in the region where tanzanite was discovered consider the stone a gift from the gods, as it was discovered by Masai cattle herders who first saw the stones after a brush fire in the area which was caused by lightning.
