Howlite Mineral Stone Natural Crystal Specimen India 25–50mm Genuine with Certificate

Overview & Authenticity

This listing features a genuine Howlite mineral specimen sourced from India, carefully selected for its quality, natural character, and visual appeal. The specimen shown in the photographs represents the exact type and quality you will receive, ensuring confidence and transparency when purchasing. Each piece is an individual natural mineral, chosen to meet consistent standards of appearance and integrity.
Every specimen is supplied with a Certificate of Authenticity, including a lifetime guarantee of genuineness, provided on a generic authenticity card. This makes the mineral suitable for collectors, educational use, or long-term display.

Mineral Identification & Composition

Howlite is a hydrous calcium borosilicate mineral, recognised for its distinctive white to off-white colouration with characteristic grey or black veining. These natural vein patterns result from matrix material infilling fractures during formation, giving each specimen a unique appearance.
The mineral commonly forms in nodular or massive habits, rather than well-defined crystals, which contributes to its smooth, organic visual texture. This specimen falls within the 25–50 mm size range, making it ideal for hand specimens, crystal grids, display cases, or educational collections.

Geological Formation

Howlite forms in evaporite-rich geological environments, typically associated with borate deposits. It develops when boron-rich fluids interact with calcium-bearing host rocks under low-temperature conditions. Over time, chemical precipitation within sedimentary settings allows the mineral to crystallise in compact masses.
Indian howlite deposits are valued for producing clean, well-contrasted material, often with visually striking veining that enhances both aesthetic and collectible appeal. The formation process reflects slow geological change in arid or semi-arid conditions where evaporation plays a key role in mineral development.

Physical Characteristics & Appearance

This howlite specimen displays the classic features for which the mineral is widely recognised. The base colour is predominantly white to pale cream, intersected by darker grey to black matrix lines that create a marbled or webbed appearance. The surface texture may range from smooth to subtly granular, depending on natural formation and finishing.
Howlite has a relatively soft hardness, making it easy to shape and polish, but this specimen is presented as a natural mineral piece, preserving its geological authenticity. Each stone is unique in pattern and form, ensuring no two examples are exactly alike.

Educational & Collecting Value

Howlite is a popular mineral among collectors due to its distinctive look and clear geological identity. It is frequently used in teaching collections to demonstrate borate mineral formation, evaporite environments, and vein infill structures. Its recognisable appearance also makes it an accessible entry-level specimen for new collectors, while still holding interest for experienced enthusiasts.
Because of its consistent size range and natural variation, this specimen is well suited for comparative study alongside other borate and sedimentary minerals.

Display & Use

With a size range of 25–50 mm, this howlite mineral is ideal for display cabinets, desks, or shelving. It also works well as part of a curated mineral set or as a thoughtful geological gift. The natural veining provides strong visual interest without the need for artificial enhancement.
As a genuine mineral specimen supplied with a Certificate of Authenticity and lifetime guarantee, this howlite from India offers a reliable, visually appealing, and geologically meaningful addition to any mineral or crystal collection.
