What is scientific provenance verification?
TSW Trace® is the name of our proprietary provenance verification solution, which is our scientific process for determining the provenance, or origin, of a product. Whether an item is natural or man-made, its chemical composition represents where it is from and how it may have been produced. Animals absorb these trace elements, isotopes, chemicals and molecules through the process of eating, plants through nutrient uptake, and minerals and stones during mineralising events. We use this information to create a unique reference chemical fingerprint for the product and its matching location of origin. This fingerprint allows us to verify a product back to a specific point of origin from any point in the supply chain – its provenance.
