US police have recovered a $US3200 ($A3049) engagement ring a man allegedly swallowed during an attempted jewellery store theft.
Ronald Perley, 52, was charged with theft and falsifying physical evidence after X-rays showed the 14-karat white-gold ring with princess-cut diamonds inside him, authorities say.
WMUR-TV reports New Hampshire police had recovered the ring on Saturday.
Perley allegedly went into a shop on Thursday asking about engagement rings.
Workers said he grabbed a ring, then swallowed it after being confronted.
Police say surveillance footage shows Perley taking the ring and putting his hand to his mouth.
Perley was being held on $US50,000 bail.
It's not clear if he has a lawyer.
