As noted in the FAQ “What is the Gilded Offering”, the gold available through the Gilded App is always London Bullion Market Association approved “Good Delivery” gold of .9999 purity. What this means is your gold will have been produced by accredited LBMA refiners in Switzerland who meet the highly detailed specifications of the LBMA’s Good Delivery List Rules, which govern such matters as the purity, weight and safe handling of the refined gold bars. Moreover, these refiners must also adhere to the LBMA’s Responsible Sourcing Programme, which is designed to combat money laundering, terrorist financing and human rights abuses.
