Konovalenko continued to make gem sculptures throughout the 1960s and 1970s. Around 1974, American wholesale diamond dealer Jack Ortman saw the sculptures on display and offered Konovalenko a house in the United States, machinery, and minerals with which to work. In pursuit of freedom, Konovalenko and his family quickly emigrated. In the early 1980s, Museum trustee Alvin Cohen purchased 20 of the Konovalenko sculptures and made them available to the Denver Museum of Nature & Science, where they have been on display ever since. It is the only collection of the remarkable Konovalenko sculptures on public display outside of Moscow.
