A billionaire’s son is suing his ex-fiancée to get back the $250,000 (£187,000) ring he gave her, after she broke off their engagement.

Wyatt Koch, 31, is demanding that Ivie Gabrielle Slocumb, 29, return the 8.24-carat diamond ring following the end of their relationship in May.

According to court documents, Koch bought the pricey Oscar Heyman cushion-cut diamond with two tapered baguette diamonds for $180,000 (£135,000) in March.

But just two months later, she allegedly ‘broke off’ the engagement and kept the ring, which Koch’s lawyers say is now worth $250,000 (£187,000).

The documents state that he is also claiming $15,000 (£11,000) in damages and has ‘demanded the return of the ring on multiple occasions.”

It also states that the would-be bride ‘received the ring as a conditional gift,’ which she refuses to return ‘despite proper demand and the condition not being fulfilled', Page Six reports.

A receipt filed with the court shows that he also splashed out on a $7,750 (£5,700) ‘platinum diamond pendant’ with 56 round diamonds, but that it’s not part of the suit.

Slocumb now has 20 days to respond to the suit, according to a summons dated Dec. 13.

Known as the flame-haired CEO of his own fashion line that specialises in quirky styles, Koch is the son of industrialist Bill Koch, the brother of Charles and David’s twin.

Bill Koch, 77, whose net worth is estimated at $1.7 billion (£1.2 billion), according to Forbes, worked with his brothers at Koch Industries in the 1970s but was later fired.

In 1983, Bill Koch and his oldest brother, Freddie, sold their interests for $470 million (£350 million) and $320 million (£240, million), respectively.

Since then, Koch Industries has gone onto become America's second biggest private company with a $100billion (£74 billion) revenue - propelling Charles and David into joint 8th and 9th places on the Forbes' richest billionaires.
