Türkiye-sourced color-change diaspore exported for the international gem trade typically carries documentation including a Türkiye Mineralogical Heritage attestation, customs declarations citing HS code 7103 (precious and semi-precious stones), and where applicable a chain-of-custody record traceable to the İlbir Mountains. Buyers transacting outside Türkiye should expect to see this provenance trail; absence of documentation is a material flag for further verification.
