Guest in Garnet: Metal Sulfide?
Recently a faceted garnet containing a striking inclusion came across the author’s desk. The solid inclusion was opaque with a metallic luster and had an uneven surface containing numerous sharp protrusions (see above). Although we were unable to definitively identify the inclusion, its opaque dark nature and crenulated texture were consistent with a metal sulfide crystal.
This inclusion scene inspired a variety of imaginative comparisons at our laboratory. Some thought it was reminiscent of the fire-breathing piranha plants from the Super Mario franchise, while others suggested it resembled a Ferrero Rocher chocolate. Regardless of what we might see in this piece, it is certain that we will continue to be fascinated by the delightful whimsy of Mother Nature’s micro-world.
