What is Cavansite?

Cavansite is a rare and beautiful phosphate mineral with the chemical formula Ca(VO)Si4O10·4H2O. It is known for its vibrant, intense turquoise-blue color, often appearing as small, spherical aggregates of tabular crystals. Cavansite is a relatively soft mineral, with a Mohs hardness of 2 to 3, and it possesses a vitreous to pearly luster. It is a hydrous calcium vanadium oxy-silicate. Its distinct color is due to the presence of vanadium, often in the V4+ oxidation state, incorporated within its layered silicate structure. Cavansite is often found in association with other rare minerals, such as stilbite, heulandite, and apophyllite, typically in basaltic or similar igneous rock formations.

Formation and Occurrence

Cavansite was first discovered in the Wombach Quarry near India’s Wagad-Gadhvi region in Gujarat, India, and was officially recognized in 1976. The primary source of cavansite has historically been the Deccan Traps region of India, specifically in cavities and fissures within basaltic rocks. These geological conditions, involving hydrothermal alteration and the presence of vanadium-rich fluids, are crucial for its formation. While India remains the most significant locality for gem-quality cavansite, tiny amounts have also been reported from other locations, including the United States (Oregon) and, less commonly, potentially within Australia’s vast geological terrains, although significant deposits are not widely documented. The rarity of cavansite means that finding it outside its primary known sources is exceptionally uncommon.

Rarity and Collector Appeal

The intense, vivid blue color of cavansite is its most striking characteristic, setting it apart from most other blue minerals. This unique hue, combined with its rarity, makes it one of the most coveted minerals among collectors. Specimens typically consist of small, radiating aggregates or spherical clusters of tabular crystals, often no larger than a few millimeters across. These small, jewel-like formations are presented on a matrix, frequently composed of other zeolites or basalt. The difficulty in obtaining sizable, well-formed crystals contributes significantly to its high value and desirability in the mineral collecting community. In 2026, cavansite remains a ‘must-have’ for many serious collectors due to its exceptional beauty and scarcity.

Understanding Cavansite’s Significance and Properties

Cavansite is a mineral that captures the imagination due to its intense color and rarity. While it doesn’t have widespread industrial applications like common minerals, its significance lies primarily in its value to mineral collectors and its unique geological context. Maiyam Group deals with minerals that have significant industrial impact, but we also appreciate the value of rare and beautiful specimens for connoisseurs.

Unique Coloration

The defining feature of cavansite is its extraordinary blue color, which ranges from a light sky blue to a deep, intense turquoise. This vibrant hue is a result of vanadium and its specific electronic configuration within the crystal lattice. This distinctive color makes it instantly recognizable and highly desirable, setting it apart in any mineral collection. The intensity and evenness of the color are key factors in determining the quality and value of a cavansite specimen.

Crystal Structure and Habit

Cavansite crystallizes in the monoclinic crystal system. It typically forms as small, tabular crystals that aggregate into spherical or botryoidal (grape-like) clusters. These clusters often rest upon a matrix, which is usually composed of other minerals such as heulandite, stilbite, or apophyllite, themselves often found in basalt cavities. The delicate, often radiating structure of these aggregates gives cavansite a unique and appealing aesthetic, different from the more geometric crystal habits of many other minerals.

Associations with Other Minerals

Cavansite is almost exclusively found in association with zeolite minerals, particularly those that form in vesicles and cavities within basaltic lava flows. This association provides crucial clues about its formation environment. The presence of vanadium in hydrothermal fluids interacting with the basaltic rock is necessary for cavansite to form. Common associated minerals include stilbite, heulandite, apophyllite, and sometimes calcite. These associated minerals often form the matrix upon which the cavansite aggregates grow, creating visually appealing and geologically interesting specimens. Understanding these associations helps in identifying potential locations and appreciating the geological story behind the specimen.

Rarity and Geographic Distribution

As mentioned, cavansite is exceptionally rare. The Wagad Gadhvi region in Gujarat, India, is the most prolific source, yielding the majority of cavansite found on the market. Small occurrences have been reported in Oregon, USA, and potentially other locations, but these are typically less significant in terms of specimen quality or quantity. While South Australia boasts a rich and varied geology, including basaltic formations and zeolites, documented occurrences of cavansite are extremely limited or non-existent in published literature. This geographical rarity means that acquiring genuine cavansite often involves sourcing from established dealers who specialize in rare minerals, primarily those originating from India.

For collectors in South Australia, the challenge is not just finding cavansite but finding reliable sources that guarantee authenticity and quality, given its extreme rarity outside of its primary discovery locations.

Where is Cavansite Typically Found?

The search for cavansite is largely dictated by its specific geological requirements and limited geographic distribution. Understanding these factors is crucial for anyone looking to acquire this rare mineral, including collectors in South Australia. Maiyam Group emphasizes that while our operations focus on strategic industrial minerals, we appreciate the unique sourcing challenges of rare collector specimens.

The Primary Locality: India

The most famous and prolific source of cavansite is the Wagad region, specifically near Wagad and Gadhvi in the Kutch district of Gujarat, India. Cavansite is found within cavities and fissures of Deccan Traps basalt. These formations are the result of ancient volcanic activity that created layered basaltic rock. Over millions of years, hydrothermal fluids rich in silica, calcium, vanadium, and water percolated through these rocks, depositing minerals like zeolites, apophyllite, and, crucially, cavansite. The cavansite typically forms as small, spherical aggregates of tabular crystals, often enhancing the beauty of the associated zeolite matrix. Specimens from this region are highly prized for their vibrant color and crystal quality.

Secondary Occurrences: United States

Cavansite has also been found in the United States, notably in theemplace formation near the type locality for stilbite in Malheur County, Oregon. These occurrences are considerably less productive than those in India and generally yield smaller crystals or less vibrant specimens. However, they represent important secondary localities that add to the mineral’s overall distribution and scientific interest. Finding high-quality cavansite from these US localities is also a significant challenge for collectors.

Potential in South Australia and Elsewhere

South Australia possesses a diverse geological landscape, including areas with basaltic rocks and zeolite mineralization, such as parts of the Great Dividing Range and the South Australian Highlands. However, documented evidence of significant cavansite finds in South Australia is virtually non-existent in mainstream mineralogical literature. The specific conditions required for cavansite formation—particularly the presence of vanadium in the hydrothermal fluids within suitable basaltic cavities—may not have been met extensively in these regions. While it is not impossible for trace amounts to exist, finding collector-quality specimens comparable to those from India is highly improbable based on current knowledge. Collectors in South Australia would likely need to source cavansite from international dealers specializing in rare minerals, primarily those who import from India.

How Collectors Acquire Cavansite

Given its rarity and limited primary localities, collectors typically acquire cavansite through:

• Specialized Mineral Dealers: Reputable dealers who focus on rare and display minerals are the most reliable source. They often import directly from the Indian localities.
• Mineral Shows and Auctions: High-quality shows and auctions can sometimes feature exceptional cavansite specimens, but buyers must be knowledgeable to avoid misidentified or over-priced material.
• Online Marketplaces: While convenient, extreme caution is advised. Many online listings may be misidentified, over-valued, or even synthetic. It is crucial to buy from trusted sellers with strong reputations and clear return policies.

For enthusiasts in South Australia, the journey to acquiring cavansite often involves looking beyond local sources and engaging with the global community of rare mineral specialists.
