Who’s pays for Thali

Hi guys, this has been an ongoing discussion between my family and friends and everyone seems to have a different answer. In Tamil culture, who pays for the thali pendant and who pays for the thali chain, is it the bride or the grooms family or is it split? I understand the pendant pattern usually follows the groom’s side but what about the expense? Anyone with recent experience, please share what you’ve done and the reasoning too, thanks!
