The stunning event was broadcast to millions on the Discovery Channel show Expedition Unknown: Egypt Live.
In the epic two-hour thrill ride, host Josh Gates guided a camera crew through the Tuna el-Gebel archaeological site where artefacts were shown off in rapid succession.
Among the finds were canopic jars – known for preserving vital organs of mummified people – and a horrifying mummy.
But, the chief find came at the end of the programme where a sarcophagus opened live for the world to see revealed a shocking find.
Nestled on top of the perfectly-preserved mummy were a gold scarab and an ISIS cross.
The pair of objects signified the person buried in the tomb had a high status – possibly a high priest.
A golden ISIS 'cross' was typically used as a symbol for the Goddess who was believed to wield great magical power.
A viewer was stunned by the find, tweeting: "This is a monumental moment. Beautifully preserved mummy. Perfectly wrapped. Gold ISIS and a scarab."
