4. (SBU) In 1989, Kriangkrai Techamong, a Thai working in the palace of Prince Faisal (son of then-King Fahd) in Riyadh, stole an estimated 200 pounds of jewelry worth approximately $20 million from the palace and smuggled it back into Thailand. Among the jewels was a 50-carat blue diamond, a prized possession of the Saudi royal family. Kriangkrai was ultimately convicted of theft in Thailand in 1990, and received a five-year sentence (he served almost three, before being released in 1994).
