Chrysocolla is a captivating gemstone, renowned for its striking blue-green hues and association with communication, balance, and creativity. While not traditionally assigned to a specific birth month, its beauty and nurturing energy make it a cherished stone for many, and it is often used alongside turquoise in December birthstone jewelry. This article will explore the history, geological origins, gemological properties, and cultural significance of chrysocolla, drawing upon available knowledge of this fascinating mineral.
History and Lore
The name “chrysocolla” originates from the Greek words chrysos, meaning “gold,” and kolla, meaning “glue.” This unusual nomenclature stems from its historical use in ancient times – as early as 300 BC – when civilizations mined the copper ore to create solder for gold. Ancient goldsmiths utilized chrysocolla, referred to as santerna by the Romans, to weld pieces of gold together, effectively acting as “gold glue.”
Theophrastus, a Greek philosopher and botanist, first documented the use of chrysocolla in 315 B.C. Throughout history, chrysocolla has inspired artists and artisans. Medieval doctors employed it in treating wounds, while Renaissance painters ground it into pigment for paints. Modern jewelry designers continue to incorporate this vibrant stone into their creations.
Legends surrounding chrysocolla also exist in Tibet and Africa, where the stone was historically used for healing purposes. A particularly intriguing legend connects chrysocolla to King Solomon’s mines in Africa, specifically regarding the Eilat stone – a composite of chrysocolla, malachite, and turquoise – which is the national stone of Israel. This association adds a layer of mystique and historical significance to the gemstone.
Geological Formation and Sources
Chrysocolla is a secondary copper mineral, meaning it forms as a result of the alteration of existing copper-rich minerals. Its formation occurs when silica-rich waters interact with copper deposits, or when hydrothermal fluids alter copper-rich rocks. This process typically takes place in regions with past or present volcanic activity, resulting in chrysocolla forming as encrustations or along fractures in host rocks. It is frequently found alongside other copper minerals such as malachite, azurite, and turquoise.
Significant deposits of chrysocolla are found worldwide. The Democratic Republic of the Congo produces high-quality specimens with vividly colored hues. Peru is known for deep blue-green chrysocolla often found intermingled with malachite. The southwestern United States, particularly Arizona, New Mexico, and Colorado, is also a bountiful source, yielding bright turquoise-like chrysocolla. Mexico offers a mix of chrysocolla, turquoise, and quartz composites, while Israel is a source of the Eilat stone. Other locations include Egypt, Chile, and Australia.
Gemological Properties
Chrysocolla is a copper silicate mineral, with a chemical formula of (Cu,Al)₂H₂Si₂O₅(OH)₄·nH₂O. Its color range is predominantly blue-green, teal, and turquoise, though yellow-green variations can also occur. The vibrant coloration is directly attributed to the presence of copper within its atomic structure.
The gemstone typically exhibits a hardness of 2.5 to 3.5 on the Mohs scale, classifying it as a relatively soft mineral. This softness necessitates careful handling to avoid scratches and damage. Chrysocolla often presents in unique formations, including botryoidal (bubbly) shapes and fibrous coatings on other rocks.
The value of chrysocolla per carat varies considerably. Standard quality material typically ranges from $5 to $50 per carat, while premium gem-quality specimens can exceed $100 per carat. The value is influenced by factors such as color intensity, clarity, and the presence of other desirable minerals like turquoise or malachite.

Symbolism and Metaphysical Beliefs
Chrysocolla is often associated with love, compassion, and feminine energy. It is believed to promote harmony, increase wisdom, and guide individuals toward discretion. Crystal practitioners suggest that chrysocolla can purify the home, environment, and mind, fostering a sense of levelheadedness and calm during turbulent times. It is also thought to decrease nervousness and irritability.
The stone is considered beneficial for those who struggle to express their feelings, enhancing creativity and communication. Its combination of earth and water energies is thought to represent the nurturing aspects of the planet. Some believe that chrysocolla should be cleansed monthly by rinsing it under warm running water and recharging it overnight with a piece of hematite.
Care and Cleaning
Due to its relatively low hardness, chrysocolla requires gentle care. It is susceptible to scratches and damage from abrasive materials. Cleaning should be performed with a soft cloth and mild soapy water. Avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these can damage the stone. It is also advisable to store chrysocolla jewelry separately from harder gemstones to prevent scratching.
Conclusion
Chrysocolla is a captivating gemstone with a rich history, unique geological origins, and a vibrant aesthetic appeal. From its ancient use as “gold glue” to its modern-day appreciation as a beautiful and expressive gemstone, chrysocolla continues to inspire and enchant. While not a traditional birthstone, its association with healing, communication, and feminine energy makes it a cherished stone for many. Its delicate nature requires careful handling, but the beauty and tranquility it embodies make it a worthwhile addition to any gemstone collection.
