Lusijoia is an Official Appraiser Licensed by INCM

When selling or appraising jewelry, gold, silver or other precious metals, trust is essential. Lusijoia is proud to be an Official Appraiser Licensed by INCM (Imprensa Nacional – Casa da Moeda), a certification that guarantees rigor, legality and transparency in all assessment processes.

But after all, what does it mean to be an official appraiser licensed by INCM?
And why should this matter to you as a consumer? In this article we explain everything to you.

The Law 98/2015 tates that it is mandatory for anyone who holds a "retailer's license for the purchase and sale of articles containing used precious metal" to be accompanied by an official appraiser. Namely:
"The retailer's license for the purchase and sale of articles containing used precious metals and the pawnshop license also depend on the declaration by the economic operator, under oath, that the daily monitoring of the activity of purchasing and selling articles containing used precious metals by an appraiser of articles containing precious metals and gemological materials, qualified under the terms of article 45, is ensured, without the need to remain at the place of sale.”

What is INCM?

The INCM – Imprensa Nacional Casa da Moeda is the entity responsible, in Portugal, for the assay office and verification of the authenticity of precious metals. It is the entity that supervises, certifies and licenses professionals and establishments that are legally authorized to carry out assessments and transactions with precious metals.

What does it mean to be an Official Appraiser?

Being a Licensed Official Appraiser involves fulfilling a series of legal and technical requirements defined by INCM, including:

• Certified training in precious metals assessment;
• Use of approved measuring equipment;
• Compliance with transparent and impartial assessment practices;
• Ability to issue well-founded opinions aligned with the daily metal price.

In practice, this translates into security for the customer: anyone who sells a gold or silver piece to Lusijoia knows that they are receiving a fair, accurate and legally valid assessment.

Authentication of Precious Metal Artifacts

The authentication of precious metal artifacts - in which INCM already has a long tradition - is currently carried out in modern laboratories, certified by the Portuguese Accreditation Institute.
When it comes to gold, silver or platinum jewelry and artifacts, authenticity is essential — not only for economic value, but also for historical, emotional and symbolic value. Authentication of precious metals is a fundamental step to ensure:

✔️ The purity of the metal (in carats or percentages)
✔️ The origin of the piece and its manufacture (national or international)
✔️ The integrity of the design and materials
✔️ The hallmark, which certifies the legality and composition of the metal alloy

The hallmark, mandatory in Portugal for pieces above certain weights, is also issued by INCM. This mark is the signature of authenticity that guarantees the consumer that they are purchasing a real and valuable piece.

Why authenticate the parts?

✅ To obtain a fair value in case of sale or inheritance
✅ For greater security when purchasing valuable jewelry
✅ As a guarantee of investment in precious metals
✅ For preserving pieces with historical or sentimental value

If you have gold or silver artifacts and want to know more about their value, trust professionals with credentials and experience. At Lusijoia, your jewelry is treated with the respect and care we know it deserves.
