OD's Jewellers Brand Guide: UNOde50

1. Brand Overview / Why UNOde50 Matters

UNOde50 is one of Spain's most distinctive modern jewellery houses—a brand defined by raw creativity, artisanal imperfection, and a refusal to conform to the mass-produced luxury model. Every piece is designed, handcrafted, and finished in Madrid, making UNOde50 an authentic representation of Spanish individuality in global jewellery.

The name "UNOde50" (meaning "One of 50") captures the founding philosophy: each design was originally produced in just 50 units worldwide. While production has expanded to meet global demand, the spirit of exclusivity and craftsmanship remains central—every collection still features limited edition pieces of 50 units, and all jewellery is handmade one-by-one at the Madrid workshop.

At OD's Jewellers, UNOde50 appeals to customers who want statement jewellery that feels lived-in and expressive, not polished and predictable.

Perfect for:

• Those seeking jewellery with tactile, perfectly imperfect artisan character
• Statement piece collectors prioritising uniqueness over uniformity
• Customers valuing Madrid handcraft heritage (130 stores, 48 countries, all made in Spain)
• Gift-givers wanting pieces that stand out from conventional jewellery box contents
• Fans of the signature UNOde50 red branding and padlock emblem

What makes UNOde50 different:

• José Azulay acquired late 1990s Madrid: President & Creative Director transforming jewellery as wearable sculpture
• 15–20 micron silver plating: Industry-leading thickness providing exceptional durability and weight
• Cannot resize rings: Multi-layer plating process makes resizing impossible without compromising integrity
• 130 stores, 48 countries physically: 80+ markets online, 2,500+ points of sale worldwide
• Wax sculpting to metal casting: Complete Madrid workshop process from design to final assembly

2. The UNOde50 Story (History & Heritage)

Late 1990s – The Acquisition & Vision

Founded in Madrid in the late 1990s, UNOde50 began as a brand operating only in Spain. In the late nineties, José Azulay acquired the UNOde50 brand with the vision of creating unique and different jewellery with original designs and limited production. His goal: break away from everything that existed in the jewellery market.

Azulay, who serves as both President and Creative Director, reimagined jewellery as wearable sculpture—pieces with personality, emotion, and human touch rather than industrial precision. The first UNOde50 collections were made up of only 50 units of each design, a commitment to quality and exclusivity that forced evolution as the brand's success grew.

2000s – International Expansion

As UNOde50 gained recognition beyond Spain, Azulay retained the brand's roots in Spanish craftsmanship and authenticity. Each piece was conceived, sculpted, and finished by hand using traditional silversmithing and leatherwork techniques rarely seen in modern fashion jewellery.

The brand's distinctive stores—minimalist, sculptural spaces lined with leather and wood, featuring signature UNOde50 red accents—began opening across Europe and beyond. These retail spaces feel more like galleries than boutiques, reflecting the same artistic personality as the jewellery itself.

2016–2020 – North American Presence & Global Growth

In 2016, UNOde50 celebrated its 20th anniversary with significant retail expansion in North America, opening stores at premium locations including New York City's World Trade Center and JFK International Airport, as well as Disney Springs, California's Valley Fair and Stanford, and Atlanta's Lenox Square.

By 2020, the brand had established itself as a premium Spanish jewellery house with a distinctive voice in the global market, balancing artistic integrity with commercial success.

Today – Creative Universe Worldwide

Currently, UNOde50 operates approximately 130 owned stores across 48 countries, with physical presence reaching customers through over 2,500 points of sale worldwide. Through online channels, the brand reaches more than 80 markets globally, making it the most internationally renowned Spanish jewellery company.

Despite this growth, all design and production remain in Spain. Over 550 professionals work to inspire people to enjoy their own identity, guided by the brand values of naturalness, freedom, and authenticity. José Azulay continues as Creative Director, personally overseeing every aspect of the brand's creative universe—from jewellery design to store concepts.

The brand's philosophy remains unchanged: creating jewellery without reservations for those who know that being yourself is revolutionary.

3. Craftsmanship & Innovation

UNOde50's Craftsmanship is Its Trademark

Every jewel passes through the hands of skilled artisans at the Madrid headquarters who sculpt, plate, and polish each piece in small batches. The signature finish—slightly irregular, tactile, and organic—is what sets UNOde50 apart from conventional jewellers.

Materials & Techniques

Proprietary Metal Alloy: UNOde50 uses a unique alloy base that respects the handcrafted characteristic of the manufacturing process. This proprietary metal is designed specifically to work with traditional artisan techniques.

15–20 Micron Silver Plating: Significantly thicker than industry standard, providing exceptional durability, lustre, and signature weight. All pieces are plated in sterling silver.

Why this matters: Standard industry plating is typically 5–10 microns. UNOde50's 15–20 micron thickness means longer-lasting finish and more substantial weight—jewellery that feels premium from the moment you hold it.

18K Gold Plating: Applied over the proprietary alloy base, hand-polished for a warm, luxurious finish.

High-Grade Natural Leather: Hand-cut, conditioned, and integrated into designs, reflecting the brand's connection to organic materials and traditional craftsmanship.

Crystals, Pearls & Resins: Manually set for light play, colour, and durability. Each stone placement is done by hand.

Hypoallergenic & Nickel-Free: All metals used are skin-safe and suitable for sensitive skin.

Design & Production Process

Design Development: Every design originates at the Madrid headquarters. The creative process begins with a theme that inspires each collection, guided by José Azulay and his design team.

Wax Sculpting: Designers create the master piece from special wax, sculpting until achieving the desired shape. This process is literally jewellery-as-sculpture.

Mould Creation: From the wax master, moulds are created where the proprietary metal alloy will be poured to obtain the first prototype.

Casting & Shaping: The alloy is cast and shaped, then undergoes refinement and detailing by hand.

Plating Process: Each piece undergoes hypoallergenic treatment with 15–20 micron silver plating or 18K gold plating—substantially thicker than standard industry plating for longevity and depth of finish.

Quality Control: Exhaustive quality controls ensure every piece meets UNOde50 standards before leaving the workshop.

Final Assembly: Jewellery is combined with leather, crystals, pearls, and other materials to create unique handcrafted masterpieces.

The Result

No two UNOde50 pieces are exactly the same. Each has a touch of originality as they are all handmade, one-by-one, at the Madrid workshop. This perfectly imperfect nature—the slight variations, the tactile quality, the visible hand of the maker—is intentional and celebrated.

4. UNOde50 in Culture & Events

Brand Philosophy & Identity

UNOde50 has become a cultural icon in Spain and beyond—worn by artists, stylists, and personalities who embrace creative individuality over conformity. The brand merges self-expression with craftsmanship, creating jewellery with its own voice capable of transmitting strength and energy.

José Azulay describes the brand's design philosophy: "We are all different. Even different depending on the day, or at the time of day. That is why each UNOde50 piece is different. I want to express moods in my designs."

The Power of Red

UNOde50 red is instantly recognisable—bold, passionate, and transgressive. Azulay chose this colour to draw customers' attention and signal that the brand offers a special experience. "Red is the colour of life, of people who have passion, who have the joy of living, and who do things with love," he explains.

In the 1990s, the brand was pioneering in being so transgressive and unconventional with colour, helping UNOde50 stand out from traditional jewellery brands.

The Padlock Symbol

The padlock serves as UNOde50's brand emblem, symbolising the protection of jewels. It appears throughout store design and packaging, acting as a guardian of the treasures given to customers with each purchase.

Store Experience

UNOde50 stores provide a unique experience based on the brand's creative universe. Spaces feature cosmopolitan, bright, and urban atmosphere combined with signature furniture chosen from antique shops worldwide and pieces of art created by the brand's creative team. Each store blends wood, metal, marble, and leather—materials that reflect the jewellery itself.

Global Presence & Recognition

With presence in major fashion capitals including New York, Paris, Milan, Madrid, London, Berlin, Rome, and Tokyo, UNOde50 continues to expand while preserving its artistic DNA. The brand positions itself as the definitive name for modern, handcrafted Spanish jewellery.

6. Care & Warranty

UNOde50-Specific Care

15–20 Micron Plating Advantage: UNOde50's industry-leading plating thickness resists tarnishing and wear longer than standard plating (5–10 microns). This substantial layer provides exceptional durability—you'll notice the difference in both weight and longevity.

Leather + Metal Fusion Care: UNOde50's signature aesthetic combines metal and leather. Never submerge leather jewellery in water. Use unscented moisturising cream or saddle soap for conditioning, applied sparingly with a soft cloth. Store leather pieces in cool, dry places away from humidity and direct sunlight.

Cannot Resize Rings: The multi-layer 15–20 micron plating process makes resizing impossible without damaging the finish and compromising jewellery integrity. Ensure accurate sizing before purchase—visit OD's Jewellers for free professional ring sizing.

Store in Original UNOde50 Red Pouch: The signature red packaging isn't just branding—it's functional protection. Store pieces in original pouches to prevent scratches and minimise air exposure that causes tarnishing.

For universal jewellery care principles, see our Jewellery Care Hub.

7. FAQs

Where is UNOde50 jewellery made? All UNOde50 pieces are designed and handcrafted at the brand's headquarters in Madrid, Spain. Every item is made one-by-one by skilled artisans using traditional techniques. Despite global expansion (130 stores, 48 countries), all production remains in Spain.

What does "UNOde50" mean? It means "One of 50" in Spanish. Originally, only 50 units of each design were produced. Today, while production has grown, the brand still releases 50-unit Limited Edition pieces with each collection to honour this heritage.

Can I resize my UNOde50 ring? No. Due to the multi-layer plating process (15–20 micron thickness), resizing is not possible without damaging the finish and compromising the jewellery's integrity. Please ensure accurate sizing before purchase. Visit OD's Jewellers for free professional ring sizing.

What makes UNOde50 plating special? 15–20 micron silver plating—significantly thicker than industry standard (5–10 microns). This provides exceptional durability (longer-lasting finish), superior lustre (deeper, richer shine), substantial weight (feels premium), and better tarnish resistance. You'll notice the difference the moment you hold an UNOde50 piece.

How do I clean my UNOde50 jewellery? Use a soft, dry cloth for regular polishing. For silver pieces, use a non-abrasive silver cleaner if needed. Avoid water, perfumes, and harsh chemicals. Leather pieces should be treated with unscented moisturising cream. Never immerse jewellery in water or cleaning solutions.

Is UNOde50 jewellery hypoallergenic? Yes. All metals used are nickel-free and skin-safe, making UNOde50 jewellery suitable for those with metal sensitivities.

Why does my silver jewellery tarnish? Tarnishing is a natural oxidation process that occurs when silver is exposed to air, moisture, and certain chemicals. It is not a manufacturing defect. Regular polishing with a soft cloth will restore the original lustre. Proper storage (in original red pouches) minimises tarnishing. UNOde50 advantage: 15–20 micron plating resists tarnishing longer than standard plating due to its exceptional thickness.

Are UNOde50 pieces one-of-a-kind? While designs are produced in multiples (not single pieces), each item is handmade one-by-one, so no two pieces are exactly identical. The handcrafted process creates subtle variations that make each piece unique. Limited Edition collections feature only 50 units per design.
