The photo below is taken from the other diamond that wasn't stolen.

Manager Online reports that one of the men wore a black suit and a red neck-tie and the other man wore a yellow shirt and navy blue trousers.
The stolen diamond from Africa weighs about 420 grams or 2,100 carats.
"A man suddenly ran away with the diamond just as we were discussing a purchase deal," Rinlapas Poonyajirapat said yesterday. "Then he jumped on a waiting motorcycle and sped away."
58 year old Rinlapas runs a recruitment agency but also doubles up as a diamond agent.
The diamond's rightful owner, 71-year-old Mr. Chakraphan Pramuansuk, was also present at the scene. He had bought two diamonds from Africa for 500,000 Baht about 15 years ago.
