Purity is central to trust in bullion. Every bar and coin produced by MBR undergoes purity validation in certified labs. Using both traditional fire assay and non-destructive spectrometric analysis, each product is checked for metal content before it enters packaging. All products are stamped with purity, weight, and serial codes to aid authentication. Customers receive detailed assay documentation, either printed or in digital form. For clients seeking external validation, third-party verification is also supported.
