Karl Christian Loibenbock, a/k/a “Karl Christian Loibenboeck,” a/k/a “Christian Bock,” of Windhoek, Namibia, is charged with one count of wire fraud in a scheme to defraud a U.S. customer out of $250,000 by selling topaz stones as high-quality rough diamonds from Angola.
According to the indictment unsealed today, Loibenbock falsely claimed the diamonds were uncertified under the Kimberley Process, a global initiative launched in 2003 to prevent conflict diamonds from financing civil wars. In reality, the stones were not diamonds at all — they were topaz, sourced in Namibia and misrepresented as valuable Angolan rough diamonds.
From September 2013 to November 9, 2016, Loibenbock used false documentation and deceptive communications to advance the fraud. On November 7, 2016, he traveled from Namibia to the United States to finalize the sale of approximately 100 carats of the fake stones, attempting to complete the $250,000 transaction.
The Kimberley Process mandates that all rough diamonds be shipped in sealed containers and accompanied by a certificate verifying they are conflict-free. Loibenbock’s alleged scheme directly exploited the trust built into this international system, attempting to pass off cheap gemstones as illicit but high-value merchandise.
If convicted, Loibenbock faces a maximum sentence of 20 years in prison, three years of supervised release, a $250,000 fine, and a $100 special assessment. No plea has been entered yet, and he remains presumed innocent until proven guilty.
The investigation was led by Homeland Security Investigations and the United Kingdom’s National Crime Agency. The case is being prosecuted by Assistant United States Attorney Vineet Gauri. The indictment underscores the reach of federal fraud enforcement — even when the suspect operates from thousands of miles away.
