“Natural Diamond Quality Assurance” Mark Scheme

The "Trade Descriptions Ordinance" of the Hong Kong SAR Government serves as the framework for establishing a program to enhance consumer trust in natural diamonds.
The objective is to provide customers with "Natural, Assurance & Protection" when acquiring natural diamonds.
The primary goal is to safeguard consumer interests by establishing standardized business practices.
Our steadfast objective is to maintain and enrich Hong Kong's standing as a premier shopping destination, the foremost hub for diamonds in Asia, and a leading global city in Asia.
