Micron-scale X-CT of a mineral inclusion within a diamond. Comprised of breyite (CaSiO3) and perovskite (CaTiO3). Measurements were conducted at the I13 beamline of Diamond Light Source. 1800 projections were collected over a 180 degree rotation on a pco.edge 5.5 sCMOS Camera using a 10x objective lens (0.3 second exposures; 0.33 μm voxels).Diamond Col-N-18, from the Collier-4 kimberlite pipe, Brazil.
