For those born under the sign of Capricorn, particularly during the month of December, a fascinating array of gemstones claim the title of birthstone. While garnet traditionally holds the primary position, modern associations extend to include the captivating blue hues of tanzanite and turquoise, as well as the icy brilliance of zircon. These gemstones resonate with the ambitious, disciplined, and practical nature of the Capricorn individual, offering both aesthetic beauty and symbolic meaning. This article will explore the history, geological origins, gemological properties, and significance of these stones, as understood through available sources.
History and Lore
The association of gemstones with specific months and zodiac signs dates back centuries, evolving through various cultures and belief systems. Garnet, the most established Capricorn birthstone, boasts a history rooted in ancient civilizations. Its name originates from the Latin word “granatus,” referencing the pomegranate, owing to the gem’s resemblance to the fruit’s seeds. While commonly recognized for its deep red coloration, garnet can also be found in shades of brown, black, and orange. In Hindu tradition, garnet was known as the Serpent stone, though the modern Western world predominantly recognizes the red variety as the birthstone for January, and by extension, for Capricorns born in that month.
Tanzanite, in contrast, is a relatively recent discovery, first identified in Tanzania in 1967. Initially named “Blue Zoisite,” it was later renamed Tanzanite in honor of its country of origin. Due to its recent discovery, Tanzanite lacks the extensive historical lore associated with older gemstones, but quickly gained popularity for its unique color and optical properties.
Turquoise, another December birthstone, has a long and storied past, valued for its calming and protective qualities. Zircon, often confused with cubic zirconia, also has ancient roots, with examples found in historical jewelry.
Geological Formation and Sources
Garnet’s formation occurs in metamorphic rocks, resulting from high-pressure and temperature conditions. Its sources are widespread, with deposits found across the globe. Blue Topaz, mentioned as a Capricorn birthstone in some sources, is found in Brazil, India, Sri Lanka, and Madagascar, and is believed to symbolize hope, happiness, and loyalty in various cultures.
Tanzanite’s geological story is unique. It is found exclusively in the Merelani Hills of northern Tanzania, making it a remarkably rare gemstone. Its formation involved complex geological processes within a specific zone of metamorphic rock.
Turquoise, as its name suggests, is often found in arid regions, forming in volcanic rocks. Zircon is also found in a variety of geological settings, including igneous and metamorphic rocks.
Gemological Properties
The gemstones associated with Capricorn exhibit a range of gemological properties. Garnet, while varying in composition, generally displays a hardness of 6.5 to 7.5 on the Mohs scale. Its color is most commonly red, but can range to other hues.
Tanzanite is known for its striking pleochroism, a phenomenon where the gem displays different colors when viewed from different angles – typically shades of blue, violet, and red. This property contributes to its brilliance and unique appearance. Tanzanite typically has a hardness of 6 to 7 on the Mohs scale.
Turquoise is characterized by its opaque nature and distinctive blue-green color, often veined with matrix material. Its hardness ranges from 5 to 6 on the Mohs scale. Zircon, with a hardness of 6.5 to 7.5, exhibits a vitreous luster and can be found in a variety of colors, including colorless, blue, and brown.

Symbolism and Metaphysical Beliefs
Throughout history, gemstones have been imbued with symbolic meanings and metaphysical properties. Garnet is often associated with protection, vitality, and grounding energy, aligning with the Capricorn’s practical and resilient nature. It is believed to inspire confidence and enhance focus.
Tanzanite, while a newer gem, is linked to transformation, spiritual growth, and the activation of psychic abilities, particularly through its association with the throat, third-eye, and crown chakras. It is also believed to promote healing and self-transformation.
Turquoise is renowned for its calming and protective qualities, offering reflection and a sense of security. Zircon is thought to inspire wisdom and promote clarity of thought.
For Capricorns, these stones are believed to enhance their inherent strengths – their ambition, discipline, and perseverance – while providing emotional balance and spiritual insight. Wearing a Capricorn birthstone is seen as a way to connect with these qualities and navigate life’s challenges with resilience and determination.
Care and Cleaning
The care and cleaning of these gemstones vary based on their hardness and other properties. Garnet, with its relatively high hardness, is durable and can be cleaned with warm soapy water and a soft brush. Tanzanite, being somewhat softer, requires more gentle handling. Avoid harsh chemicals and ultrasonic cleaners, opting instead for mild soap and warm water. Turquoise is particularly sensitive and should be cleaned with a soft cloth and mild soap, avoiding any abrasive materials. Zircon should also be cleaned gently with warm soapy water and a soft brush. It is advisable to remove gemstone jewelry before engaging in strenuous activities to prevent damage.
