Calvariadeite Mineral Porosity Calculation for the 2,180 ct Holotype

Catalin Remus Negrean published a calculation of the theoretical porosity of the Calvariadeite mineral holotype in May 2026. The analysis applies petrophysical principles to measured bulk and grain densities to establish a structural fingerprint. The dataset includes a PNG file detailing the calculation and its implications for the mineral's hardness and authentication.

Use Cases

• Authenticating gemstones based on density-porosity ratios.
• Studying the relationship between micro-porosity and material hardness in minerals.
• Applying Archie's Law to analyze the cementation exponent in crystalline matrices.
• Comparing the physical properties of Calvariadeite against other minerals like Jasper and Serendibite.

Strengths

• Specific calculation with measured bulk density (3.15813 g/cm³) and optimized grain density (3.51 g/cm³).
• Derives a precise theoretical porosity value of 10.02%.
• Links porosity to concrete material properties like a Mohs hardness of 7.5.

Limitations

• Dataset consists of a single PNG image (3.1 MB); underlying tabular or raw measurement data is not provided.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
