What is the purity of gold offered by Gilded and who certifies it? 

Purity of the Gold.

As noted in the FAQ “What is the Gilded Offering”, the gold available through the Gilded Offering is always Swiss-refined, 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 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 LBMA’s Responsible Sourcing Programme, which is designed to combat money laundering, terrorist financing and human rights abuses. The LBMA is recognized as the global leader in setting standards for the world’s gold markets.

In addition, the quality, and LBMA and refiner bona fides, of all gold purchased through the Gilded Offering are verified by Bureau Veritas, the nearly two-century-old global firm devoted to establishing trust amongst individuals, public authorities and companies in all matters, including those between businesses and their customers.
