Question 1
What is XRF spectrometry in plain English?
It is a testing method used to analyse the elemental composition of a material without relying solely on appearance or destructive assumptions. In practical charity-retail terms, it helps a specialist assess what a precious-metal item is made of more confidently than a visual guess can. That matters because hallmarks may be absent, misleading, worn, or misunderstood, and because value should not depend on branch confidence alone.
