In Coimbatore, a goldsmith by the name Radhakrishnan Sundaram Acharya wanted to create awareness about wearing masks to prevent the spread of COVID-19. For this, he decided to design masks with gold and silver threads. The process is not easy, he explains. “First, big gold rods have to be drawn out to 0.06 millimetres thickness so that they can be woven together,” he says. This allows the metal to be flexible and makes it easy to sanitise. Once, the metal has been woven, the layer is knitted onto a cloth mask and then polished to complete the look. “The entire process takes around five to seven days,” he adds. This 18-carat gold mask sold by RK Jewel Tech (Acharya’s store) comes at a price of Rs. 275,000, while the 92.5 sterling silver mask costs around Rs. 15,000.
