The large glimmering blue sapphire pictured in the prospective from the Phillips auction house was, he was convinced, a gem his company once owned before it was audaciously snatched from a Milan hotel nearly two decades earlier.
"I looked at the certificate, and I had this feeling. I said to myself: 'That's it. That's it'," he told AFP in an interview last week.
The story reads like the plot of a mystery novel, with a multitude of twists and turns, a second disappearance and an as yet unresolved ending centred around a New York pawn shop.
On November 14 that year, days before the anticipated sale in Geneva focused exclusively on Cartier jewels, auction house Antiquorum displayed the pieces at the Four Seasons hotel in Milan.
According to Swiss daily Le Temps, more than 50 people were in the viewing room when the bracelet, the main attraction of the show, vanished.
"It was terrible. It is always a shock when you get robbed," Totah said.
Until November 8, 2015, when he received an email from Phillips offering a Geneva viewing of a 59.57-carat Kashmir Sapphire ahead of an auction in New York.
Totah did not view the stone, but studied the certificate carefully.
Considering "there are basically no stones with this origin, weight and shape out there ... It is "very, very, very probably" the stolen H&T sapphire, he said.
The fact that the gem in the prospectus was a little smaller than the one stolen 19 years earlier did not make Totah less suspicious, since jewel thieves will often file down a stone to alter its weight or shape.
