Good delivery bars are manufactured by accredited refiners who are regularly subjected to double-blind tests by independent assayers. The bars spend their lives in accredited storage facilities and are transported only by accredited couriers.
They are the only form of gold automatically trusted upon receipt by professional buyers.
Once a year we send in independent specialist assayers who inspect the bullion and report to our auditors, who then publish the report on their own website for your inspection.
We are completely confident regarding the quality of the bullion in our care, and provide a full, permanent, 100% guarantee of its quality.
BullionVault gold bars are all of known weight and purity, which exceeds 99.5%. As with the rest of the professional bullion market only the pure gold content (gross weight * purity) is traded and recorded. The gold in your BullionVault account is therefore 100% pure.
Silver, platinum and palladium are different. Good delivery silver and platinum bars are refined to 99.9% purity or better for silver and 99.95% purity or better for platinum and palladium and traded at gross weight. The good delivery silver, platinum and palldium in your account is at least 99.9% or 99.95% pure, respectively.
