Video: US jeweller offers free guns to engagement ring buyers 'who hunt deer, not diamonds' Jeweller Harold van Beek at Jewelry By Harold in North Liberty, Iowa said that he wanted to "do something for the boy who doesn't like to hunt for diamonds but likes to hunt for deer." Customers must spend $1,999 (£1,240) or more on an engagement ring to qualify for the free gun and the rifle offer is subject to Iowa laws on gun ownership. Those barred include criminals and addicts. The deal starts Thursday and will run through to the end of October.
