If cold December gave you birth

The month of snow and ice and mirth

Place on your hand a turquoise blue;

Success will bless whate’er you do.

Modern December Birthstones

December babies are super lucky! Of all the months of the year, only a few feature three separate birthstones. December birthstones are turquoiseblue zircon, and tanzanite. Because this is a cold winter month, it should be no surprise that all three of these gemstones exhibit various tones and hues of blue.

Initially, turquoise and lapis lazuli were the birthstones for December. Both show blue hues that reflect winter. However, this list would evolve over time.

By the early 1950s, blue zircon replaces lapis lazuli due to growing customer interest. By 2002, tanzanite would also come to join turquoise and blue zircon as an official December birthstone.

Turquoise

One of the world’s most ancient gems, turquoise has been around for more than 3000 years ago. The name turquoise originates from the French expression pierre tourques, or “Turkish stone.” The name reflects the fact that the gemstone came from modern-day Turkey. This gemstone displays a beautiful blue to green color, sometimes featuring a matrix of its host rock. The national gem of Tibet, turquoise has long been considered a stone that guarantees strength, prosperity, and safeguards from evil. Also, there are many varieties of turquoise, and each has distinct characteristics.

Blue Zircon

Blue zircon is a brilliant blue gemstone with a higher refractive index compared to any other blue gemstone. Zircon’s name is either derived from the Arabic word zarkun, meaning “red,” or a combination of the ancient Persian phrase zar, meaning “gold” and gun, meaning “color.” Despite this name, zircon occurs in a myriad of colors. This beautiful gemstone is famous for its outstanding brilliance, strong dispersion, or fire, the tendency to split white light into a spectrum of colors.

Tanzanite

A relatively new gemstone, tanzanite is the blue to violet variety of zoisite. This rare gemstone comes from only one place, the Merelani Foothills of Tanzania. Known for displaying a transition of color from blue to violet, with flashes of red, tanzanite exhibits pleochroism, meaning that the hue of the gemstone shifts as you change its position. Also, many think this gemstone boosts the immune system, communication skills, and sharpen the mind. There are several varieties of tanzanite with distinct characteristics.
