Gül Gül, the Golden Sign CEO, previously told Reuters that her company sells seven to eight units to Russians “every day,” and said they often pay in cash or “bring gold.”

At the time, she told Reuters that her clients are wealthy Russians, but not oligarchs. However, she later told the Journal that “some” are. Golden Sign did not immediately respond to Insider’s request for comment.
