Jewelry worth nearly $500,000 disappeared in New York City after a 67-year-old Peruvian woman who was wearing it mysteriously collapsed and died during Fourth of July weekend, her family revealed Monday.

"She was not sick, she was super healthy. She never smoked a cigarette in her life," the woman’s son told DNAInfo.com. "There is no money or jewelry that will bring her back."

The woman, whose identity is being withheld at the request of her family, was visiting the Big Apple with her husband to buy two diamond rings and a bracelet to bring back to their upscale jewelry business in Lima, the son said.

After making the purchase, she wore the jewelry for safekeeping, but then collapsed in her room at the St. Regis Hotel in Manhattan before dying two days later at New York Presbyterian Hospital, police told DNAInfo.com.

The husband and son rushed to make arrangements to send her home for a funeral, but in the hours before their flight, they realized that the $445,000 worth of jewelry she was wearing had vanished, according to authorities.

The father and son reached out to people who had come in contact with the woman, but could not recall when they last saw the jewelry, the website reports.

On Oct. 19, the son returned to New York City to file a police report for the missing items.

The city’s medical examiner says the cause of the woman’s death has not yet been determined, but no jewelry was noted during the examination and they had received no reports of missing jewelry.

The hospital and hotel did not immediately respond to requests for comment by FoxNews.com.
