X-ray CT Scan of a 23.45-Carat Carbonado Diamond from Central African Republic

The University of Texas High-Resolution X-ray CT Facility (UTCT) provides a high-resolution X-ray CT scan of a carbonado diamond specimen. The scan comprises 970 slices with a voxel size of 1.02 µm, captured on 19 September 2010. This research was supported in part by National Science Foundation grant EAR-0948842.

Use Cases

• Analyze the internal porosity and structure of carbonado diamonds based on the 3D volumetric scan data.
• Study geological formation processes of diamonds based on the high-resolution internal imagery.
• Develop or test 3D image segmentation algorithms based on the detailed, micron-scale scan slices.
• Compare material inclusions and defects in natural diamonds based on the specimen's scan.

Strengths

• High-resolution scan with a precise voxel size of 1.02 micrometers.
• Scan date and principal investigators (Richard Ketcham, Christian Koeberl) are explicitly documented.
• Data provenance is clear, originating from a known academic facility (UTCT) with a supporting NSF grant.

Limitations

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