Mineralogy of Zoisite
Mineral Family: Sorosilicates
Chemical Composition: Ca2Al3 (SiO4)3(OH)
Color: Green, yellow-green, white/grey
Crystal System: Orthorhombic
Fracture: Conchoidal to uneven, brittle
Luminescence: Orangey-yellow (long wave)
Transparency: Translucent to Opaque
Location: Zoisite is found in Australia, Germany, Japan, Namibia, Norway, Scotland, Spain, Tanzania, and the United States.
Mineral Family: Zoisite is a Silicate mineral. Silicate minerals form the largest family of minerals, including more than 25% of all known minerals and 40% of all common minerals. In addition to being a major part of the Earth’s crust, Silicate minerals have also been found on the moon and in meteorites. Silicates are minerals which contain the elements Silicon (a light gray shiny metal) and Oxygen (a colorless gas). Together, these two elements form a tetrahedron – a shape similar to a pyramid – with a Silicon atom in the center and Oxygen atoms at each of the four corners. These tetrahedra connect with other chemical structures, in six different ways, to form various minerals and rocks. There are six main groups of Silicate minerals, and these main groups are further subdivided into secondary subdivisions, such as Quartz and Feldspar. Zoisite belongs to the sorosilicate family, in which two tetrahedral groups share a single oxygen molecule. It is closely related to Danburite, Dragonstone, Epidote and Vesuvianite.
Formation: Zoisite is formed by regional metamorphism and by the hydorthermal alteration of igneous rocks. It is sometimes found in Quartz veins and pegmites.
Mining: Zoisite is mined in its primary deposit, often found near Ruby and other gemstones. The most valuable type of Zoisite is the blue/purple gemstone Tanzanite, found only in Tanzania. The second most valuable is pink Thulite.
Enhancements: Most Zoisites are fully natural and have been enhanced only by tumbling, cutting, and polishing. Tanzanites are often heat-treated to bring out their color and to remove any brown spots and patches.
History of Zoisite
Zoisite is a relatively “new” stone to the metaphysical community and so was not included in any ancient lapidaries, texts that describe gemstones and their powers. While transparent Zoisite crystals may be shaped into gemstones for jewelry, Zoisite is most commonly known as an opaque green mineral that serves as a matrix for low-quality Rubies. For more information, please see: Ruby Zoisite.
Pure Zoisite was first identified in 1797, by Slovanian geologist, Sigmund Zois (1747-1819). He had purchased the mineral from a dealer and soon after realized it was a brand-new stone which had not been described before. Zois sent the specimen on to his colleague, Abraham Gottlob Werner (1749-1814), the so-called “Father of German Geology.” Werner wrote the first formal description of the new mineral, and named it after Zois.
The most valuable type of Zoisite is the blue/violet found exculsively in the Mererani Hills of northern Tanzania. It was discovered in 1967 and became a popular gemstone due to the marketing efforts of Tiffany and Co. who named the distinctive Blue Zoisite – Tanzanite. The original deposit remains the only know deposit, acutely limiting the available supply and keeping demand high. Today Tanzanite is mined in pits and tunnels deep underground, divided into four blocks, and containing hundreds of individual claims, each closely guarded and mined around the clock.

Healing Properties of Zoisite
Spiritual: Zoisite invites us to let our spirit fly free, and to cast off the chains from society that demand we confirm and follow the rules. Zoisite reminds us that we have a good mind and a good heart, and can walk our own unique path without harming anyone else. It encourages us to live in the moment and to truly see the beauty all around us. It is a stone for spiritual growth and healing, transforming negative vibrations into positive energy. Zoisite is also a very comforting stone to work with when faced with a terminal illness and while contemplating questions of death and immortality. Zoisite is attuned to the Root, Heart, Third Eye Chakras and linked to the astrological sign of Gemini. It is connected to the element of Storm and vibrates to the number 4.
Emotional: Zoisite gives us emotional strength during times of high stress or illness. It soothes away fear, anger, and hopelessness, and reminds us that we have survived many such times before, and we will survive this one as well. Zoisite whispers to us that life is still sweet and far too precious to waste feeling sorry for ourselves. It helps us to stay positive and hopeful for the future, while staying in the moment and focused on whatever is most important.
Mental: Zoisite stimulates our sense of creativity, sense of purpose, and ability to follow through. This makes it an excellent talisman for artists who need to finish creative projects or for anyone starting an unusual business venture. It helps us to remember what we are doing, why we are doing it, and what step to take next! Zoisite shakes us out of our inertia when we feel stuck and inspires us to take action.
Physical: Zoisite is most often used by metaphysical healers to treat the reproductive and sexual organs, particularly the testicles and ovaries. It is believed to reduce inflammation and neutralize excessive acidity in the body. It is also said to be useful for treating the heart, spleen, pancreas, and lungs.
Always use wisdom when considering crystal therapies for healing.

I have been doing business with this source since the earliest days in my business. They are a major tumbling company and have more varieties, in more sizes, than any other known source. The owners visit many small and industrial-size mines personally. For artisanal-mined deposits in sub-Sahara Africa, the owners work with Gem Dealers who deal directly with the part-time miners. The majority of these Gem Dealers are women.
Some, but not all, of their stones are labeled with country-of-origin. For those that aren’t, I have to ask the owners personally. They tend to get impatient with questions. As I’ve learned more about mining practices in individual countries, I have become increasingly selective about what I will purchase from them. However, they remain my preferred source for most of sub-Sahara Africa.
