We use 99.99% investment grade 1 kilo gold bars that are fully allocated. Our gold is sourced from an international gold refiner called Produits Artistiques Métaux Précieux (PAMP), which is a part of the London Bullion Market Association (LBMA). PAMP is one of only three refineries worldwide designated as ‘Approved Good Delivery Referees’ by the LBMA, that means our gold is guaranteed to be top quality!
