Your studio is the issuer
A certificate of authenticity records the details your studio supplies about its own piece. You remain the issuer. Digital Unboxing & COA Kit creates and presents the certificate alongside care instructions and your maker's note. It does not inspect products, authenticate resale goods, issue gemstone grading reports or manage laboratory Certificates of Analysis.
