December Birthstones: Tanzanite, Zircon and Turquoise

Most months throughout the year are only associated with a single birthstone, but those who are born in December are privileged to choose between three different birthstones when they would like to purchase jewelry that contains a gemstone that resembles their birth month. The three stones associated with the month of December are Tanzanite, Zircon and Turquoise. In this post, we hope to provide more details about each of these stones to help those looking to buy a gemstone that represents their birth month a better idea of which stone would best suit them individually.

Tanzanite Gemstones

Tanzanite gemstones are considered the primary December birthstone. These gemstones are still relatively new to the world, especially when compared to the rest of the gemstones deemed as birthstones. In fact, it was only in 1967 when Tanzanite gemstones were first discovered. These stones were discovered in Tanzania. The name of the stone was derived from its country of origin.

The Tanzanite is considered one of the most popular stones today, mostly due to its unique color hues and its beauty. These gemstones are, however, very rare. Tanzanite gemstones are made of zoisite, which is a particular mineral that causes the dec birthstone to reflect a vivid blue color.

On the Mohs hardness scale, the Tanzanite ranks seventh, making the stone as hard as a Quartz gemstone, but less durable than a Topaz or Corundum. This, however, does not mean that the Tanzanite gemstone rings are not durable. These stones can be worn on a daily basis when fitted in certain jewelry, such as a pair of earrings.

Zircon Gemstones

The secondary birthstone associated with the month of December is Zircon. It is important to note that these gemstones are available in a variety of colors, but it is the blue variety of the Zircon gemstone that is deemed the secondary birthstone of December.

Zircon is widely found within the crust of the Earth and these gemstones date back to as much as four billion years. The gemstone is classified as a Nesosilicate and is rated at 7.5 on the Mohn hardness scale. This means Zircon gemstones are durable and very hard – also somewhat harder than Tanzanite gemstones – making them the perfect stone to be used in necklaces, bracelets and earrings. When used in rings, however, a person should consider taking extra care of their jewelry and not wear it as an everyday accessory.

Turquoise Gemstones

The third gemstone dubbed as the birthstone for December is the Turquoise gemstone, a beautiful stone that features a light blue color. These stones are mentioned throughout history and can be tracked down to ancient times. Mentions of Turquoise gemstones are found in ancient Egyptian history, with reports claiming that Pharaohs wore necklaces that contained several Turquoise stones. Turquoise gemstones are also mentioned in Native American history, as well as in the history of many other civilizations.

There are many different uses for Turquoise gemstones. It is often used in necklaces, as well as many other types of jewelry. Additionally, Turquoise gemstones are also often seen fitted into certain types of clothing. While these gemstones tend to have a blue color, some feature hues of dark green in addition to their blue color.


Those people born in December have three gemstones associated with their birth month. These include the Turquoise, Zircon and Tanzanite gemstones, each offering a set of features that makes the specific stone suitable for certain individuals born within the month of December. Apart from the fact that these stones are dubbed as the birthstones of December, they also make perfect gifts for certain occasions.
