Since May 1st 2023, new legislation is in force regarding the provision of information that will be mandatory when selling natural and/or synthetic diamonds (mounted or unmounted) to consumers.

A company that wishes to sell natural or synthetic diamonds (loose or mounted in a piece of jewelry or watch) to a consumer, must provide information regarding the characteristics of the good(s) before the consumer is bound by an agreement:

• The fact whether the good is/contains natural or synthetic diamond(s) as well as the number of stones;
• The fact whether the natural or synthetic diamond(s) is/are treated/untreated
• The weight of the natural diamond(s) or the synthetic diamond(s)
• If applicable, the type of treatment to which the natural diamond(s) or the synthetic diamond(s) has/have been subjected.

The information is provided by means of a paper document or, if the consumer agrees, on another durable data carrier, which is handed over to the consumer. The information provided is readable and clear and must contain at least the following information: 

1. The company number;
2. The trade name or company name; 
3. The address where the company is established; 
4. The identification of the good. 

The document is dated and signed by a natural person who can legally represent the company. The legislator also provides a template document, which is deemed to comply with these requirements of the Royal Decree. You can find this documents (in both FR and NL) at the 'interesting downloads' section on this page.

AWDC actively supported the development of this new legislation because it contributes to a transparent and sustainable diamond and jewelry trade.
