However, the couple separated about two years ago.
Documents filed with the Companies Office state Bell Boyd became a director of Wunderkammer Limited in August 2011, two days before Crane was removed as a director. In May last year, Crane was declared bankrupt.
Bell Boyd told the Herald on Sunday she bought the business from Crane three years ago and helped clear $220,000 of debt.
She said some of the jewellery allegedly stolen belonged to a customer.
"All the work was produced last year," Bell Boyd said.
"Two lots of jewellery, three pieces each, belonged to collaborative work I did in conjunction with other people. Mark never worked on the jewellery."
Crane said the charges were the start of a long battle which would bring "a lot of stuff" out of the woodwork.
He declined to comment further.
Murray Crane told the Herald on Sunday he supported his brother.
He said the charge was "malicious".
"It seems very strange someone can get charged from shoplifting from what is effectively their business that they have worked in, operated and founded, and been involved in for 10 years," Murray said.
Mark Crane has been bailed to reappear in court on January 25.
