Those who were born in December are lucky enough to have two birthstones: turquoise and tanzanite. Turquoise has a robin’s egg blue color and often showcases natural veins, or matrix patterns, which are remnants of the rock it was mined from. While both clean and matrix turquoise are popular, collectors prize turquoise from the now-closed Sleeping Beauty mine in Arizona, which has a rare, vivid hue and no matrix. Designer Laura Stephanie says, “The formation of this stone and its pure blue coloration is a geological miracle. The blue color has been traced to a large copper deposit at the mountain it is mined from.” 

As for tanzanite, it’s one of the most popular pleochroic gemstones (stones that exhibit different colors in various lights), and it is a relatively new gemological finding. Tiffany & Co. introduced it in 1967, and ever since, designers have incorporated the rare gemstone into artful pieces that highlight its intense violet-blue to pale purple hue. Our roundup of December birthstone jewelry includes both turquoise and tanzanite jewelry, allowing you to choose a piece that feels personal to you.

Another way you can embrace a December birthday is by wearing zodiac jewelry. If you were born between November 22 and December 21, you can enjoy Sagittarius zodiac jewelry. Otherwise, those born between December 22 and January 19 can sport Capricorn zodiac jewelry.
