Wildlife trade monitoring network Traffic revealed an "emerging trend" of making and smuggling beads, bracelets and bangles and rhino horn powder.
The lead investigator told BBC News the trade in rhino horn was now "morphing" into a market for luxury items.
At least 7,100 rhinos are estimated to have been killed in Africa since 2007.
Today, about 25,000 of the animals remain.
Julian Rademeyer from Traffic explained that the production of rhino horn "trinkets" mirrored some of the patterns seen in the trade in ivory.
