Shraddha Kapoor’s jewellery brand Palmonas is in discussions to raise Rs 200-250 crore from mid-market private equity firm Xponentia Capital. The round is expected to value Palmonas around Rs 1,600-1,800 crore, up by more than three times from the last round, one of the persons said. The company had raised Rs 55 crore from Vertex Ventures earlier this year at a valuation of Rs 500-550 crore.
