The months of December and January are graced by a diverse selection of birthstones, offering a spectrum of color and lore. While modern lists often highlight Tanzanite and Garnet respectively, traditional associations include Turquoise, Lapis Lazuli, and Zircon for December, and solely Garnet for January. This article will delve into the characteristics, history, and significance of Garnet and Tanzanite, drawing upon available information to provide a comprehensive overview for gemstone enthusiasts.
Garnet: A Stone of Warriors and Vitality
Garnet, traditionally the birthstone for January, is not a single gemstone but rather a family of silicate minerals with varying compositions. The name “garnet” is derived from the Latin word granatus, meaning “seed-like,” a reference to the gem’s resemblance to pomegranate seeds. While commonly associated with a deep red hue, garnets occur in a remarkable range of colors, including purplish, green, yellow, and orange.
Historically, garnets have been prized for millennia. Archaeological evidence suggests their use as gemstones and abrasive materials as early as the Bronze Age. In ancient Rome, garnets were frequently used in signet rings to seal important documents. The stone’s association with warriors and royalty stems from a belief that it offered protection from injury. Some cultures connected red garnets to life-giving blood, symbolizing vitality, love, and light.
The garnet family is complex, encompassing several species and varieties. Pyrope and almandine are among the best-known red varieties, frequently found in jewelry. Other notable types include hessonite (golden), spessartine (vivid orange), demantoid (green, first mined in Russia in 1868), and tsavorite (green). The variety of colors and compositions within the garnet family makes it a versatile and popular choice for jewelry of all types. Garnets generally exhibit good transparency and can be found in relatively large crystal sizes.
Tanzanite: A Modern December Gem
Tanzanite, a relatively recent addition to the birthstone chart, is the modern birthstone for December, alongside Blue Zircon and Blue Topaz. Discovered in the Merelani Hills of Tanzania in 1967, this gem quickly gained popularity for its striking blue to violet hues. Tanzanite is a variety of the mineral zoisite, and most rough material begins as brownish in color. Heat treatment is essential to reveal the vibrant blue and violet tones that characterize this December birthstone, and this color change is permanent.
Tanzanite’s durability is rated between 6 and 7 on the Mohs scale of hardness, making it susceptible to abrasion and scratching. It can be cracked by sudden temperature changes or exposure to very high temperatures. Hydrochloric and hydrofluoric acids can also damage the stone. Due to its relative softness, tanzanite is best suited for settings in earrings or pendants, though it can be worn in rings with protective mountings and careful handling.
Historically, Tanzanite has strong ties to the cultures of East Africa. The Apache believed that following a rainbow to its end would lead to turquoise, and that attaching turquoise to a bow or firearm would improve accuracy. The Pueblo people associated turquoise with the sky, while the Hopi believed it was created by lizards. Tanzanite itself also holds cultural significance, being considered a national treasure in Tibet, believed to grant health, good fortune, and protection from evil. It is also associated with peace and was a popular gem in the funerary mask of King Tut.

Symbolism and Metaphysical Beliefs
Both Garnet and Tanzanite carry rich symbolic meanings. Garnets, historically associated with warriors, symbolize protection, vitality, and courage. Red garnets are often linked to love and passion, while other colors may represent different energies and intentions.
Tanzanite, a more modern gem, is often associated with transformation, intuition, and spiritual awareness. Its vibrant color is believed to stimulate the mind and enhance psychic abilities. The gem is also thought to promote communication and self-expression. Turquoise, a traditional December birthstone, symbolizes serenity and purity.
Care and Cleaning
Proper care is essential to maintain the beauty of both Garnet and Tanzanite. Garnets, with their relatively high hardness, are durable and can be cleaned with warm, soapy water and a soft brush. Ultrasonic cleaners can be used with caution, avoiding those with strong vibrations.
Tanzanite requires more delicate handling. Warm, soapy water is the recommended cleaning method. Ultrasonic and steam cleaners should never be used, as they can damage the stone. Due to its susceptibility to scratching, tanzanite jewelry should be stored separately from harder gemstones.
