| Comments: | are all trapiche-like sapphires, with white “arms” developing around the core. Various sections of the samples were distinguished by visual observation. Detailed inspection of the raw stone reveals subtle changes in different zones. Further polishing made the phenomenon more visible. The arms are generally white, reaching from the mineral’s border to the center and aborting at the cores. The cores are substantially darker in color, typically dark blue or black, whereas the sectors are blue. It is not a product of basaltic magma crystallization but is more likely derived from the lower crust and is classified as magmatic sapphire. | |
