A new chapter that reflects our essence, our savoir-faire, and the desire to continue offering a coherent and inspiring luxury experience.
We are pleased to share an important milestone in our journey: the integration of our three boutiques under one single brand, Maison Roca. This step symbolizes the maturity of a project born from a passion for fine jewellery and exceptional watchmaking, now presented to the public with a unique identity and a unified voice.
A story that evolves
Since our beginnings at the emblematic Mercat de l’Or on Meritxell Avenue 52, we have grown through three spaces that, each in their own way, have interpreted the same spirit of excellence, beauty, and authenticity.
Today, Mercat del Diamant, Bàsic Mercat and Maison Roca become one single house: Maison Roca, a name that encapsulates years of dedication, trust, and passion for creations that endure.
One brand, multiple expressions
This integration allows us to offer a smoother and more coherent experience, where each boutique — at 18, 50 and 97 Meritxell Avenue — retains its own personality while speaking the same language of elegance and savoir-faire.
At 50 Meritxell Avenue, Maison Roca exclusively hosts the Breitling brand, a benchmark of Swiss watchmaking and mechanical excellence.
At 18 Meritxell Avenue, gemmology takes centre stage — with diamonds, gemstones, and brands such as Shamballa Jewels and Niessing, expressing our passion for designer jewellery, contemporary craftsmanship, and pieces with a soul.


At 97 Meritxell Avenue, our own Maison Roca collection shines — a line of fine jewellery created with the same passion and precision that guide our selection of brands. Each piece reflects our savoir-faire, our love for noble materials, and our commitment to traceability and responsible beauty.
Each space holds its own treasures, inviting you to discover them at your own pace and experience Maison Roca in all its diversity.
From the most contemporary collections to the most exclusive pieces, everything reflects the same philosophy: Bold Luxury Life — a way of understanding luxury that highlights authenticity and human connection.
Our commitment
With this new stage, we reaffirm our commitment to quality, sustainability, and personalized service.
Our boutiques and team continue to offer expert guidance, dedicated attention, and a curated selection of brands that embody the values defining us: creativity, rigour, and passion for beauty.
