A 10-carat diamond ring given to Bobbi Kristina Brown by her late mother Whitney Houston has gone missing, Radar Online reported. The 22-year-old was reportedly wearing the $250,000 ring on Jan. 31, the day she was found unresponsive in a bathtub at her Atlanta home.

The ring is reportedly the same that Bobbi Kristina was wearing when she announced her engagement to her boyfriend Nick Gordon in July 2012. The aspiring actress had posted a photo of the ring on her Instagram account at the time.

According to reports, sources claimed that Bobbi Kristina’s family has been curious about the whereabouts of the ring after Gordon mentioned it during his interview with Dr. Phil that aired last week.

In the interview, Gordon asked his mother about the ring who replied that she had kept it safe. A member of the Houston family later called Dr. Phil to help find the ring, Radar Online reported. However, Gordon and his mother stated that they were talking about a different ring and not the one that was given to Bobbi Kristina by her Grammy award-winning mother, a source reportedly said.

Gordon is currently in rehab under a residential substance abuse treatment program. The 25-year-old is being investigated over Bobbi Kristina’s current condition. A criminal probe was launched by police after they found injuries on Bobbi Kristina’s body.

The Houston and the Brown families have been feuding over Bobbi Kristina’s situation as she continued to show no signs of improvement.
