Viren Bhagat isn’t a household name, but in the rarefied world of haute joaillerie he’s spoken of in reverential tones. One of the world’s most important contemporary jewelers, this dashing artist seldom speaks publicly, so when he does, people listen. “Mapping a Legacy of Indian Jewels,” a two-day conference organized by Saffronart, an auction house headquartered in India, headlines Bhagat and other luminaries in the field of baubles such as Lisa Hubbard and Joanna Hardy. Curated by celebrated historian Usha Balakrishnan, expect a mix of jewel history and appreciation. —Gayatri Shah
