Sterling Jewelers and Zale Corp. failed to reach an agreement during mediation in their ongoing legal squabble over Zale’s advertising claims about its Celebration Fire diamond.
“On May 2, 2013, the Parties participated in mediation with the designated Mediator,” said a letter filed with the court on June 7. “The Parties negotiated in good faith but did not come to a resolution.”
As a result, the suit is continuing, the filing added.
The two parties were ordered to mediation on March 27.
Sterling sued Zale in November over Zale’s claim that its Celebration Fire diamond was the “most brilliant diamond in the world.” Sterling calls that claim misleading. Zale says the claim has been backed up by independent research.
