A new chapter that reflects our essence, our savoir-faire, and the desire to continue offering a coherent and inspiring luxury experience.
We have unified our three boutiques under a single brand: Maison Roca. This step gives a clear and coherent identity to the project we have developed throughout our history. The unification marks a new stage for a project born from a passion for fine jewellery and watchmaking, now presented to the public with a unique identity and a single 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 its 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, 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 18 Meritxell Avenue, entirely dedicated to high jewellery, gemmology takes centre stage — with exceptional diamonds and coloured gemstones — alongside houses such as Shamballa Jewels, Niessing or Tamara Comolli, which embody our passion for designer jewellery, contemporary craftsmanship and creations with a soul.


At 50 Meritxell Avenue, Maison Roca brings together a carefully curated selection of fine jewellery and watchmaking brands, and it is the only one of our boutiques where you can find Breitling timepieces — a proper reference in Swiss watchmaking and mechanical excellence.
At 97 Meritxell Avenue, the Maison Roca collection shines, with Maison Roca & Tracemark label, coexisting with other prestigious jewellery and watchmaking brands, as MESSIKA, FRED or CHANEL. This space hosts our most personal creations, designed with the same passion and precision that guide our brand selection. Each piece reflects our savoir-faire, our love for noble materials, and our commitment to traceability and responsible beauty.

Each Maison Roca space holds a different treasure: the art of watchmaking, the essence of designer jewellery, and the creativity of our own collections: three spaces, one Maison — the experience of a luxury that speaks with a single voice.
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 personalised service.
Our boutiques and team continue to offer expert guidance, dedicated attention, and a curated selection of brands that embody the values that define us: creativity, rigour, and apassion for beauty.
Please contact us to find out where these three spaces of style and exclusivity await you: Maison Roca.
