When images of the microscopic virus were first published, Dr. Vorobev, a jewelry firm in Kostroma, a town 300 kilometers north of Moscow, thought the form of the virus would make a beautiful pendant.
For just $ 20, the silver medallion in the form of a virus - which causes an acute respiratory illness known as Covid-19 - could become yours.
"People were buying it and posting it on social media," said Pavel Vorobev, the firm's founder. "It simply came to our notice then. It has a viral effect. "
The virus, which originated in China, has infected more than 1 million people worldwide and killed more than 50,000 people.
The company, Dr. Vorobev also produces heart, lung and DNA helix pendants.
As for allegations that he is being shown to be insensitive, Vorobev said the addicts have no intention of taking advantage of the international crisis.
"Our followers are respectable people - doctors and people working in medicine," he said, adding that some coronavirus patients had bought the pendants in question to donate to staff who cared for them.
The firm plans to donate coronavirus sprays to the cage for first-line doctors.
