December is unique among the months, boasting not one, but three recognized birthstones: blue zircon, blue topaz, and tanzanite. Traditionally, December was associated with turquoise and lapis lazuli, but modern lists have expanded to include these vibrant blue gems. Each stone carries its own distinct history, metaphysical properties, and appeal, making December birthdays particularly rich in gemstone options. This article will explore the origins, characteristics, and significance of these December birthstones, drawing upon available historical and gemological information.
A History of December’s Gems
The tradition of associating specific gemstones with each month dates back to ancient times, though the specific stones have varied across cultures. The practice gained prominence in medieval times, with gemstones believed to possess unique powers and influence. The modern birthstone chart, as it is known today, began to take shape in the 20th century, with the National Association of Jewelers (now Jewelers of America) establishing a standardized list.
While turquoise and lapis lazuli represent the traditional gems for December, the inclusion of blue zircon, blue topaz, and tanzanite reflects evolving tastes and the discovery of new and captivating gemstones. These colored gems were considered blessed to those who wore them in rings, pendants, and other jewelry, a practice rooted in ancient medieval times. The trend of wearing birthstones isn’t a recent fashion, but a tradition with deep historical connections.
