A peculiar inclusion with metallic luster (see above) was observed in a 5.31 ct faceted pinkish orange padparadscha sapphire. Though reminiscent of an inclusion previously observed in garnet (Summer 2023 G&G; Micro-World, p. 226), this occurrence in sapphire displayed a more irregular and pronounced spiky texture. The combination of nearly pyramidal protrusions and sloped valleys gives this inclusion a fascinating and unique topography. While neither inclusion was conclusively identified, the opacity and dark metallic appearance suggest a metal sulfide.
