carbH_C_A: X-ray CT Scan of a 23.45-Carat Carbonado Diamond

994 high-resolution X-ray CT slices of a 23.45-carat carbonado diamond from the Central African Republic. The specimen was scanned at the University of Texas High-Resolution X-ray CT Facility on 23 September 2010 with a voxel size of 5.47 µm. This research was supported by a National Science Foundation grant (EAR-0948842) and the data should be acknowledged to UTCT, Richard Ketcham, and Christian Koeberl.

Use Cases

• Analyze the internal porosity and structure of a carbonado diamond based on the high-resolution CT slices.
• Study the formation history and potential extraterrestrial origin of carbonado diamonds based on 3D volumetric data.
• Develop or test image segmentation algorithms for geological materials based on the provided CT scan stack.
• Compare the internal features of this carbonado specimen to other diamond types using the detailed 3D model.

Strengths

• High-resolution volumetric data with a precise voxel size of 5.47 micrometers.
• Data is associated with a specific, large (23.45 carat) and rare carbonado diamond specimen.
• Clear provenance and attribution requirements stated for the scanning facility and researchers.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• The single-specimen focus may limit generalizability for broader geological studies.
