These are attractive and colourful specimens of calcite crystals from Mexico. Calcite is one of the most common and varied minerals on Earth, prized for its wide range of colours and crystal formations. Some of the most popular varieties include orange, blue, green, honey, red, black and pink mangano calcite. In this lot, you have 4 of these colours.
Many people associate coloured calcites with cleansing, emotional balance, and energy amplification. Different colours are believed to carry different energetic qualities:
- Orange - creativity, confidence, and motivation.
- Blue - calm communication and emotional soothing.
- Green - growth, renewal, and heart-centered healing.
- Honey calcite - focus, personal power, and learning.

This is an attractive specimen of calcite crystals from Limestone Quarry, Povodje, Ljubljana, Slovenia. The entire top surface of the specimen is covered with many sharp well formed golden calcite crystals. It is in excellent condition.
Calcite is found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere. Calcite is the principal constituent of limestone and marble.

Iceland Spar, also known as optical calcite, is a clear, transparent variety of calcite famous for its unique optical property called double refraction. When you place the crystal over text or an image, it appears doubled — a visual effect that occurs because light splits into two rays as it passes through the crystal. This fascinating trait made Iceland spar historically important in early optical instruments and scientific studies, including navigation and the development of polarizing microscopes.
It’s typically colorless or very lightly tinted and forms naturally in sharp, rhombohedral shapes. High-quality Iceland spar is most famously found in Iceland, though it also occurs in places like Mexico, the U.S., and China.
Iceland Spar (optical calcite) is often associated with clarity, insight, and truth. Because of its double refraction property, some see it as a symbol of seeing beyond surface appearances — helping to highlight different perspectives or reveal hidden aspects of a situation. It's thought to support clear thinking and honest communication, making it a favorite for meditation or decision-making spaces.

This is a natural cluster formation of large calcite crystals with hematite inclusions. This piece has some white color to translucent crystals with areas of orange/red coloring from hematite inclusions, with sharp tabular crystal formations. There are some nicks and imperfections on a few crystals but would still shine in the proper setup. They don't take away from how interesting this piece is. Would be a nice addition to any new or existing collection.

Weight: 160.5 Grams / 5.7 oz
Origin: Mined in Lane Quarry, Westfield, Hampden Co., Massachusetts, USA
Amber golden calcite from Mexico is a beautiful variety of calcite known for its rich golden to honey-colored tones. It often forms in sharp, well-shaped crystals like dogtooth clusters or larger, chunky crystals with smooth faces. These pieces can have a soft glow when light passes through them, making them visually warm and inviting. Much of this material comes from regions like Durango and Chihuahua, areas well known for producing high-quality calcite in many colors.
Amber golden calcite is often associated with confidence, warmth, and personal growth. Some believe it helps boost self-esteem and encourages a positive, motivated outlook, making it a helpful stone during times of change or new beginnings. It's also thought to carry a gentle grounding energy, helping balance emotions while keeping one connected to a sense of inner strength.

Iceland spar, formerly called Iceland crystal (Icelandic: silfurberg [ˈsɪlvʏrˌpɛrk], lit. 'silver-rock') and also called optical calcite, is a transparent variety of calcite, or crystallized calcium carbonate, originally brought from Iceland, and used in demonstrating the polarization of light.
The most common crystal structure of Iceland spar is rhombohedral, but other structures, such as scalenohedral or prismatic, can form depending on formation conditions. Iceland spar is primarily found in Iceland but can occur in different parts of the world with suitable geological conditions such as China.

This is a natural cluster formation of calcite on calcite crystals or two variations of the mineral found in a cracked concretion in a coal mine in Oskaloosa, Mahaska County, Iowa, USA.
It is a specimen consisting of two types of calcite on matrix. The first type is a coating of iridescent, dark calcite on the matrix. The second type are white crystals of calcite. It is in good condition. Would be a nice addition to any new or existing collection.
