What is Calcite?
The definition of calcite is a carbonate mineral, made primarily of calcium carbonate (CaCO₃). It is part of the carbonate mineral group and is known for its striking crystal formations, which can be found in a wide range of colours.
Many people wonder, "Is calcite a mineral or a rock?" The answer is simple: calcite is a mineral. However, it often forms in sedimentary rocks, meaning you might hear it referred to in that context.
What Type of Rock is Calcite?
Since calcite forms mainly in sedimentary environments, it’s commonly found in limestone and marble, both of which are widely used in construction and sculpture. So, while calcite itself isn’t a sedimentary rock, it’s a key component of many. If you’re wonderig if calcite is an igneous rock, the answer is no—igneous rocks come from magma, and calcite forms through different processes.
What Does Calcite Look Like?
Calcite appears in a variety of colours, including white, yellow, green, blue, orange, pink, and black. It can be transparent, translucent, or opaque, with a surface that ranges from smooth and polished to rough and rugged in its raw form.
Its crystal shape is often scalenohedral, meaning pointed and multi-faceted, though it can also take on rhombohedral or massive (chunky and unstructured) formations. With a hardness of 3 on the Mohs scale, calcite is relatively soft compared to minerals like quartz.
One of its most fascinating properties is double refraction—when you look through a clear piece, objects may appear doubled!
Where is Calcite Found?
Calcite is one of the most abundant minerals on Earth and is found in a wide range of environments. Some of the most significant sources include:
- The United States – Especially in limestone caves and sedimentary rock formations.

Frequently Asked Questions About Calcite
Can Calcite Touch Water?
While brief contact with water may not immediately damage calcite, it is not water-safe for prolonged exposure. Due to its calcium carbonate composition, calcite can gradually dissolve or weaken when submerged in water for extended periods. If you need to clean calcite, it’s best to wipe it with a dry or slightly damp cloth rather than rinsing it directly under running water.
Why Does Calcite Glow?
Some varieties of calcite exhibit fluorescence, meaning they glow under ultraviolet (UV) light. This is due to the presence of trace elements and impurities such as manganese, lead, or rare earth elements. Iceland Spar and fluorescent calcite from Mexico are particularly well known for their ability to glow in vibrant shades of red, blue, pink, or green under UV light.
Is Calcite a Precious Gem?
Calcite is not classified as a precious gemstone, like diamonds or rubies, due to its softness and abundance. However, some rare and highly transparent forms, such as Iceland Spar, are sought after by collectors and can be valuable. Additionally, polished and coloured calcite specimens are widely used in crystal healing, making them desirable for their aesthetic and metaphysical properties.
Is Calcite Rare?
Calcite is one of the most abundant minerals on Earth. It is found worldwide in sedimentary, metamorphic, and hydrothermal environments. However, some rare varieties, such as optical-grade Iceland Spar or deep-coloured specimens, can be more difficult to find and are considered more valuable.
What is Another Name for Calcite?
Calcite is sometimes referred to as calcium carbonate, which is its chemical composition (CaCO₃). Specific varieties also have unique names, such as Iceland Spar (a clear, optical-grade calcite) or Honey Calcite (a golden-yellow form).
Why Does Calcite React with Acid?
Calcite reacts with weak acids, such as vinegar or hydrochloric acid, because it’s made of calcium carbonate. When acid is applied, it causes the mineral to fizz or bubble as carbon dioxide gas is released in a chemical reaction.
What is the Relief of Calcite?
In geological terms, relief refers to how a mineral appears under a microscope in relation to its surrounding environment. Calcite has high relief, meaning its edges and crystal structure stand out clearly when viewed under polarised light.
Does Calcite Have Magnetic Properties?
Calcite is not magnetic. Unlike some iron-rich minerals, calcite does not respond to magnets or display any magnetic properties.
Can Calcite Be Used in Jewelry?
Since calcite has a hardness of only 3 on the Mohs scale, it’s quite soft and prone to scratching or damage. For this reason, calcite is not commonly used in rings or bracelets, which experience frequent contact, but it can be set in pendants, earrings, and decorative pieces with proper care.
Why is Some Calcite Transparent and Others Opaque?
The level of transparency in calcite depends on impurities and crystal structure. Pure calcite, like Iceland Spar, is completely transparent and can display double refraction, while more common varieties with trace elements and internal fractures appear opaque or cloudy.
How Can I Tell the Difference Between Calcite and Quartz?
Calcite and quartz may look similar, but they have distinct differences:
- Hardness – Quartz is much harder (7 on the Mohs scale) compared to calcite (3). Quartz cannot be scratched with a knife, while calcite can.
- Acid Reaction – Calcite fizzes when exposed to acid, but quartz does not react.
- Crystal Shape – Calcite tends to form scalenohedral or rhombohedral crystals, whereas quartz forms hexagonal prismatic crystals.
What Are Three Interesting Facts About Calcite?
- Calcite makes up most of the world's limestone and marble, which are used in everything from buildings to sculptures.
- Certain types of calcite glow under UV light, displaying bright pink, blue, or green fluorescence.
- Calcite is found in coral reefs, shells, and even microscopic marine organisms, playing a crucial role in the Earth's carbon cycle.
Where Do You Put Calcite in Your House?
Calcite can be placed in various areas depending on its colour and energy properties:
- Clear calcite – Meditation or study spaces to enhance clarity and focus.
- Green calcite – Bedrooms for emotional balance and healing.
- Orange calcite – Creative spaces to inspire motivation and confidence.
