Every bar, fully traceable.
Every Auvalis bar carries the hallmark Auvalis engraved on its face, a unique serial number, and ships with an individual certificate of analysis signed by the assayer in charge.
From raw gold intake to delivery, every gram is tracked under full BACEN registration and OECD due-diligence procedures. Provenance is verifiable at any point in the chain of custody.
The certificate of analysis links each bar to its purity test, refining batch, and assayer signature. Documents are independently retrievable through institutional channels.
Every bar leaves the refinery in a tamper-evident sealed plastic capsule. The packaging carries the hallmark, the bar's serial number, weight, fineness and refining batch — visible without breaking the seal.
Printed on the packaging, a QR code links directly to the digital Assay Certificate for that specific bar. A single scan reveals the laboratory analysis, the assayer's signature, and the chain-of-custody record — anywhere, anytime.
Digital verification
Scan the QR code on the packaging to open the bar's Assay Certificate, with full analysis and authentication.
