One very famous piece of scarab themed jewelry was found in 1999 by an archaeologist named Howard Carter. He found this necklace located in King Tut's tomb in the Valley of the Kings. it is a pectoral necklace, which means it went around the neck but hung over the entire pectoral region of the body. Italian geologists performed a chemical composition test on King Tut's scarab necklace and determined the scarab was made out of natural desert glass for the king, who reigned from 1333 to 1323 B.C. This special type of glass can only be found in the Great Sand Sea of the eastern Sahara desert. Because this special glass only comes from such a remote area, the glass for this amulet had to have traveled over 500 miles.
What the geologists also discovered that was extremely special about the glass that made up the scarab center, is that this type of glass is only produced by the impact on sand by a meteorite or comet. This necklace symbolized the voyage of the sun and moon through the sky, which also brings up some questions of whether the Ancient Egyptians believed this glass center piece was even more important because of it celestial origins.
This pectoral necklace is inlaid with carnelian, lapis lazuli, calcite, obsidian turquoise, and red, blue, green, black and white glass.
