Step 2: Analysis using XRF Technology
Before performing any other tests, technicians place your items inside an X-ray fluorescence (XRF) machine. To test them without causing damage. The X-ray excites the metal’s atoms; the machine then measures the ‘fluorescent’ rays the sample releases. and uses that data to determine the exact percentages of gold, silver, copper, and other alloys.
Step 3: Fire Assays are the Most Accurate Method
Fire Assays require the destruction of a small amount of gold (300-500 mg). From your jewelry for a 100% accurate measurement of the purity of your gold. The Fire Assay process involves two stages: Cupellation and Parting. Both are essential for testing your gold.

This HUID, a six-character alphanumeric code, enables consumers to track their gold’s authenticity through the BIS Care App.
