Purity Shown, Not Asserted
Two identifiers belong to two different holders: your BIS registration is yours, and a piece's HUID belongs to the article as it was hallmarked at the assaying centre. Most jewellery sites collapse both into one badge. We build required HUID and caratage fields on hallmarked listings and your registration as a site-level field — and stone grades stay attributed to the grading laboratory, because that grade is the lab's opinion rather than your claim. We assay nothing and certify nothing.
