Quality Assurance 

At Maria João Bahia, we are dedicated to delivering unparalleled quality in every piece of jewellery we offer. Our commitment to craftsmanship and meticulous attention to detail ensures that each item you acquire is a genuine work of art.

Authenticity and Materials

We have established longstanding partnerships with reputable suppliers known for fair and transparent practices. Our stone supplier maintains direct connections to Antwerp, a hub for diamonds and precious stones. Our gold and silver are certified by Portuguese law, with a standard of 19.2kt Gold and 925 Sterling Silver. Pearls are sourced from a certified supplier. 

Skilled Artisans 

Our artisans are an integral part of our extended family, and they are the soul of our brand. Many have been with us since the beginning and knowledge is passed down through generations. We prioritize their training and technical growth, providing them with the time and resources to innovate. 

Design Excellence 

Maria João Bahia, the founder and owner, also serves as our Design Director. With years of experience, she possesses a deep understanding of customer needs and a unique ability to transform personal histories into exquisite jewellery. Working closely with our bench jewelers, they form a harmonious partnership.

Quality Control 

Every piece undergoes rigorous testing before reaching our clients. We meticulously examine each item for any minor imperfections, conduct pressure tests to ensure secure settings, and, if necessary, make adjustments to achieve perfection.

Customer Satisfaction 

Above all, customer satisfaction is our guiding principle. Witnessing how our pieces carry profound emotions and make a significant impact in our customers' lives brings us immense joy. We recognize the immense value our work holds and its potential to positively influence the lives of our customers.

Certificates and Warranties

We ask you to keep your invoice, as it is the relevant document and serves as a guarantee. Certificates provide additional information.
Maria João Bahia offers warranties that exceed those stipulated by law, providing the opportunity for the customer to have their pieces maintained without a time limit.
