This Digital Passport is tied to OTZ-2026-01762 and remains accessible after the gemstone leaves available Otzera inventory. The QR code on the case always resolves to this canonical record rather than to a temporary sales page.
The Otzera 50 is a founder-led, species-relative collector rating. It is not a laboratory grade, appraisal, price guarantee, investment representation or universal ranking across all gemstones. Identity, treatment, origin evidence, laboratory documentation and condition are disclosed separately where applicable.
