The practice of associating gemstones with specific months, known as birthstones, is a tradition steeped in history and symbolism. These “stones of birth” are believed to bestow good fortune and strength upon those born in the corresponding month, and have become cherished components of jewelry and personal adornment. The origins of this practice are complex, evolving over millennia from ancient religious texts to modern commercial standardization. This article will explore the historical development of birthstones, tracing their roots in biblical lore, Hindu traditions, and ultimately, the standardization efforts of jewelry organizations.
The earliest documented connections between gemstones and specific meanings can be found in the Bible. In the Book of Exodus, God instructs Moses to create a breastplate for Aaron, the high priest, adorned with twelve different gemstones. These stones, representing the twelve tribes of Israel, were believed to possess powerful properties and were engraved with the names of the tribes. The specific gems used are subject to interpretation due to the imprecise mineral naming conventions of the time. Descriptions like “chrysolite” could refer to multiple gems, including topaz or peridot, based on their color and inclusions. The stones mentioned include carnelian, chrysolite, beryl, jacinth, agate, amethyst, topaz, onyx, and jasper, forming a foundational link between gemstones and spiritual significance. This breastplate was considered a “shield of judgment,” and Aaron was to wear it when entering holy places, further cementing the gemstones’ association with divine power.
This biblical association laid the groundwork for later interpretations linking gemstones to months of the year. During the eighth and ninth centuries, Christian traditions further developed this connection, assigning specific stones to the twelve apostles. Simon Peter was linked to jasper, Andrew to ruby, and James and John to emerald, among others. This practice continued to evolve, with the Book of Revelations listing foundation stones for the new Jerusalem, again aligning gems with a calendar-based system.
Beyond the Judeo-Christian tradition, similar beliefs existed in other cultures. In Hinduism, the Ratna Pariksha, a 5th-century text, detailed the relationships between gemstones, deities, and celestial bodies. The navaratna, a Sanskrit term for nine gemstones, were central to this system, with a bright red ruby or spinel surrounded by other gems. These pieces were believed to grant cosmic harmony and symbolize status and wealth. Vedic astrologers would recommend specific stones based on individual birth charts to harness planetary energies or ward off negative influences. This demonstrates a parallel development of gemstone symbolism independent of Western traditions.
The association of gemstones with birth months continued to evolve over time, with regional variations in the assigned stones. The lack of standardization meant that different cultures and even different regions within a single country might attribute different gems to the same month. This ambiguity persisted until the early 20th century. In 1912, “The Jewelers of America” organization sought to address this inconsistency by adopting an official list of birthstones. This list, while attempting to standardize the practice, was itself updated in 1952 by the Jewelry Industry Council of America. Further refinements occurred in recent years, with the American Gem Trade Association adding tanzanite as a December birthstone in 2002 and spinel as an additional August birthstone in 2016. This ongoing evolution reflects both a desire for clarity and a recognition of the increasing variety of gemstones available.
One example of a gemstone with a rich history and evolving association is peridot. Derived from the Arabic word faridat, meaning gem, peridot was valued in ancient Egypt as early as the second century BCE. It was found on the island of Zabargad, which, due to its harsh conditions, was ominously named the “Island of Death” or “Ophiodes” (snake island). Despite the dangers of mining, peridot from Zabargad was highly prized and remains desirable today, with fine specimens displayed in museums worldwide. Peridot was also used in medieval Europe, adorning chalices and churches, and was considered a protective talisman against evil spirits. Today, peridot is primarily sourced from China, Myanmar, Pakistan, Tanzania, Vietnam, and the United States, and is the recognized birthstone for August.
Garnet, the birthstone for January, also has ancient roots. Its name is derived from the Latin word granatus, meaning seed-like, referencing the gem’s resemblance to pomegranate seeds. Garnet has been used in jewelry for millennia, and its deep red hues have long been associated with passion and vitality.
The modern tradition of birthstones is therefore a synthesis of ancient beliefs, religious symbolism, and commercial standardization. While the original associations may have been based on mystical or spiritual properties, the contemporary significance of birthstones often centers on personal sentiment and aesthetic appeal. They remain popular gifts, particularly for birthdays and anniversaries, and continue to captivate with their beauty and enigmatic allure. The standardization efforts of jewelry organizations have provided a common framework, but the underlying fascination with the power and symbolism of gemstones persists, connecting us to a long and vibrant history.
