While gemstones associated with specific months are typically more commonly known, there are a few rare and lesser-known birthstones that begin with the letter "U." Among these are Unakite and Uvarovite, both of which possess distinctive characteristics, geological origins, and cultural significance. Though not widely recognized as traditional birthstones, they offer a compelling blend of beauty, symbolism, and rarity that appeals to gemstone enthusiasts and collectors alike.
This article delves into the fascinating world of these two gemstones, exploring their historical uses, geological formation, physical properties, and the spiritual meanings attributed to them across various cultures. Through a detailed examination of available data, we uncover the unique qualities that make Unakite and Uvarovite stand out among the vast array of gemstones in the world of gemology.
History and Lore
Unakite: A Stone of the Earth
Unakite is a type of granite that was first discovered in the Unakas Mountains of North Carolina, USA. As its name suggests, it is named after the region where it was first identified. The stone is composed of a blend of feldspar, epidote, and quartz, giving it a distinctive mottled pattern of pink and green. Its aesthetic appeal led to its use in jewelry, particularly in the form of cabochons and beads. Though it is considered a semi-precious stone, Unakite is not particularly durable and is best suited for low-impact jewelry pieces such as pendants and earrings.
While Unakite is not officially listed as a traditional birthstone in the official American birthstone lists, it has gained recognition in the metaphysical and holistic communities for its emotional and spiritual properties. It is often associated with healing and grounding, making it a popular stone for meditation and emotional balance.
Uvarovite: A Sparkling Green Gem
Uvarovite is a rare variation of garnet, known for its brilliant green color. It was first identified in 1832 and named after Count Sergei Semenovitch Uvarov, a Russian nobleman and statesman. Unlike the more common red garnets, Uvarovite is notable for its vivid green hue, making it a highly sought-after gemstone among collectors.
Uvarovite is not typically used in mainstream jewelry due to its limited availability and lower durability compared to other garnet varieties. However, when found in suitable form, it is prized for its sparkling appearance and is often used in high-end, bespoke jewelry pieces. Its rarity and vibrant color have also made it a subject of interest in gemological research and museum collections.
Like Unakite, Uvarovite is not part of the traditional birthstone list, but it is sometimes used in alternative or modern birthstone systems that include a broader range of gemstones beyond the classic 12-month list. In metaphysical circles, Uvarovite is believed to carry positive, protective energies, often associated with good fortune and spiritual enlightenment.
Geological Formation and Sources
Unakite: A Product of Metamorphism
Unakite is a metamorphic rock that forms under high pressure and temperature conditions, typically in granite formations. It is composed of three main minerals:
- Feldspar (usually pink or white)
- Epidote (green mineral)
- Quartz (often clear or white)
The interplay of these minerals gives Unakite its characteristic mottled pink and green appearance. It is primarily found in the Unakas Mountains of North Carolina, USA, but it has also been discovered in other regions such as Australia and South Africa, where similar geological conditions exist.
Due to its relatively low hardness (on the Mohs scale), Unakite is not suitable for high-wear jewelry such as rings. It is best used in pendants, earrings, and other delicate pieces where it can be polished to a smooth, lustrous finish.
Uvarovite: A Rare Garnet Variety
Uvarovite is a garnet mineral, specifically a member of the grossular garnet family, and is chemically composed of calcium chromium silicate (Ca₃Cr₂(SiO₄)₃). It forms in metamorphic rocks, particularly in limestone and marble environments where chromium-rich minerals are present.
Uvarovite is known for its brilliant green color, which is caused by the presence of chromium. It is most commonly found in Russia, where it was first discovered in the Ural Mountains. Other notable sources include Austria, Brazil, and Madagascar, where small deposits of Uvarovite have been identified.
Due to its rarity and small crystal size, Uvarovite is not commonly cut into large gemstones. Instead, it is often used in small, cabochon-style pieces or as inclusions in other gemstones. Its sparkling green appearance and high refractive index make it a highly desirable gemstone among collectors and gemologists.

In some traditions, Uvarovite is considered a stone of good fortune and is believed to attract abundance and prosperity. It is often used in jewelry and personal adornment to carry these positive energies with the wearer.
Care and Cleaning
Unakite: Gentle Handling and Protection
Due to its relatively low hardness and porous nature, Unakite requires gentle handling to avoid scratches and damage. It should be cleaned with a soft cloth and warm, soapy water, avoiding harsh chemicals or ultrasonic cleaners, which can cause erosion or discoloration.
Unakite should be stored separately from harder gemstones to prevent scratching, and it should be avoided from exposure to high heat or direct sunlight, which can fade its colors over time. It is best suited for occasional wear rather than daily use, and it is ideal for jewelry pieces that are not subject to heavy impact.
Uvarovite: Avoiding Abrasive Cleaning
Uvarovite, while more durable than Unakite, still requires careful cleaning and storage to maintain its brilliant luster. It should be cleaned with a soft cloth and mild soap, avoiding abrasive materials or harsh chemicals that can scratch or dull its surface.
Uvarovite should be stored in a soft pouch or jewelry box to protect it from scratches and impacts. It is best suited for jewelry that is worn occasionally, and it should be avoided from exposure to high heat or strong light sources, which can affect its color and clarity.
Due to its rarity and high value, Uvarovite is often insured or appraised to ensure its protection. It is also recommended to avoid wearing Uvarovite jewelry during physical activities or when handling rough materials, as it can easily chip or crack.
