In this article, we will explore the concept of "official import diamonds" and find out why official customs import documents are a prerequisite when buying diamonds?
What Are Official Import Diamonds?
Official import diamonds must meet 3 simultaneous criteria: Legal import process, International quality certificate, and Ethical mining standards. Unlike smuggled or untraceable goods, official diamonds are strictly controlled from extraction in reputable mines (South Africa, Canada, Botswana, etc.) until they arrive at port and clear customs in Vietnam.
- Transparent legal status: Possess customs declarations and are recognized as legal by the State.
- International certificates: Accompanied by reputable appraisal certificates such as GIA (Gemological Institute of America), IGI, or AGS.
- Ethical process: Adhere to the "Kimberley Process," ensuring diamonds are not from conflict zones (Conflict-free diamonds).

Official import diamonds are diamonds with legal import processes, international quality certificates, and ethical mining standards.
