Chrome Diopside Mineral Natural Green Crystal Specimen Genuine with Certificate

Overview & Authenticity

This listing features a genuine Chrome Diopside mineral specimen, carefully selected for its natural crystal form, rich green colour, and overall geological quality. The photographs show the actual specimen you will receive, ensuring complete transparency and confidence when purchasing. Each piece is a naturally occurring mineral, individually chosen rather than bulk-graded, making every specimen unique in structure and appearance.
The mineral is supplied with a Certificate of Authenticity, including a lifetime guarantee of genuineness, provided on a generic authenticity card. This ensures the specimen is a true natural example, suitable for collectors, educational use, or long-term display.

Mineral Identification & Classification

Chrome Diopside is a chromium-bearing variety of diopside, a calcium magnesium silicate mineral belonging to the pyroxene group. The presence of chromium within the crystal lattice produces the intense green coloration for which this mineral is prized, ranging from vivid grass green to deep emerald tones.
Diopside minerals crystallise in the monoclinic crystal system and typically occur as prismatic crystals, granular aggregates, or crystal fragments. Chrome diopside is especially valued when colour saturation is strong, as even small specimens can display striking visual depth.

Geological Formation & Origin

Chrome Diopside forms in igneous and metamorphic environments, most commonly within ultramafic rocks such as peridotite and kimberlite. These rock types originate deep within the Earth’s mantle, giving chrome diopside a direct geological connection to deep Earth processes.
The mineral crystallises under high-temperature conditions during the slow cooling or metamorphic transformation of mantle-derived rocks. Chromium becomes incorporated during crystal growth, resulting in the distinctive green colour that differentiates chrome diopside from standard diopside varieties.

Physical Characteristics & Morphology

This specimen exhibits the classic physical characteristics of chrome diopside. Crystal surfaces may show a vitreous lustre, while fractured or granular areas reveal internal clarity and colour zoning. The mineral’s colour intensity often varies depending on crystal thickness and light interaction, enhancing its visual appeal from multiple viewing angles.
Chrome diopside has a well-defined crystal structure that allows it to retain sharp edges and clear forms, contributing to both its aesthetic and scientific value. Its natural form has been preserved, maintaining the authenticity of the specimen.

Scientific & Educational Significance

Chrome diopside is of interest to mineralogists and geology enthusiasts due to its chemical composition and mantle-related origin. It is commonly included in educational collections to demonstrate pyroxene mineralogy, chromium substitution in silicate minerals, and the relationship between surface mineral specimens and deep geological environments.
Because of its distinctive colour and identifiable structure, chrome diopside serves as an excellent reference specimen for both introductory and advanced mineral studies.

Collecting & Display Appeal

This chrome diopside specimen is well suited for display in mineral cabinets, drawers, or desktop collections. Its vivid green colour contrasts strongly with neutral backgrounds and complements a wide range of other mineral types. It is equally appropriate for private collections, academic use, or as a distinctive geological gift.
Supplied with a Certificate of Authenticity and lifetime guarantee, this genuine chrome diopside mineral represents a visually striking and geologically meaningful addition to any mineral or crystal collection.
