Certification & Hallmarking

According to Portuguese Law no. 98/2015, all silver, gold and platinum products must be hallmarked. The hallmark must include the type of precious metal and its purity. All of our pieces, made with precious metals, are hallmarked, as stated in the Portuguese Assay Office Legal Marks table.
The buyer, in case of doubt about the authenticity of the hallmarks, can use, for verification purposes, the services of hallmarking agencies. For more information, click here
