Spinel

Post by JW »

This spinel exhibits rhombic dodecahedral crystal faces with very small octahedral modifications at the corners. Spinel is almost always forms octahedrons or rarely cubes, well developed spinel dodecahedrons are extremely rare in nature (although very common amongst the garnets). Associated with and included by green prismatic chestermanite, black ludgwigite and white calcite. From an undisclosable locality in eastern Fresno County, California. 20X Mitutoyo, WeMacro with 2 um steps, reversed 150 Raynox on 58 mm tubes, Canon D50 with diffused flash at 1/250. The 197 images were slabbed stacked with ZS, 15 overlap 3, first with PMax, then with DMap, then some in-program touchups. PS only to change size.
