Thewa is my middle name,” says Roopa Vohra, the Mumbai-based jewellery designer who resuscitated the dying Mughal craft in the 1990s. Thewa involves embossing intricately worked-out sheet gold on molten glass of varied hues. The result is a stunning play of sparkle and colour, with the gold and glass playing up each other’s strengths. Around 400 years ago, artisans would make an elaborate piece, such as a pillbox or a pankhi, every few years, present it to their royal patrons, and be rewarded with a bag full of gold guineas. They would repeat the process after their gold guineas were spent. Of course, the bigger the piece, the bigger the reward.
