Regarding the line: "To confirm the purity of the gold, a modern laboratory uses XRF technology to accurately assess its quality in order to ensure the owner receives fair market value for it."

As someone who works in the gold refining and trading industry, I can assure this is wrong. XRF is normally used as a quick preliminary check and some mining companies use it for forward selling, but final exchanges are always done based on Fire Assay results, normally repeated several times for quality assurance. 202.155.85.18 (talk) 01:01, 28 November 2016 (UTC)[reply]
