UNOde50 Jewellery Guide
UNOde50 is one of Spain’s most distinctive modern jewellery houses — 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.
The name “UNOde50” (meaning “One of 50”) captures the founding philosophy: each design was originally produced in just 50 units worldwide. At OD’s Jewellers, UNOde50 appeals to those who want statement jewellery that feels lived-in and expressive.
1 | Why UNOde50 Matters

What Makes UNOde50 Different
Wax Sculpting Process
Every design starts as a hand-sculpted wax master. The organic imperfections of the original sculpture transfer into the final metal piece.
15–20 Micron Plating
Industry-leading thickness vs 5–10 microns standard. Provides exceptional durability, substantial weight, and deeper lustre.
The Padlock Emblem
UNOde50’s signature symbol — cast directly into each piece during the lost-wax process, not attached separately.
José Azulay
President & Creative Director who acquired the brand in the late 1990s with the vision of jewellery as wearable sculpture.

3 | Craftsmanship & Materials
The Madrid Workshop Process
- Wax Sculpting: Designers create the master piece from special wax
- Mould Creation: Moulds created from wax master for metal casting
- Casting & Shaping: Proprietary alloy cast and refined by hand
- Plating: 15–20 micron silver or 18K gold plating applied
- Quality Control: Exhaustive checks before leaving the workshop
- Final Assembly: Leather, crystals, and pearls combined by hand
Perfectly Imperfect
No two UNOde50 pieces are exactly the same. The slight variations and tactile quality — the visible hand of the maker — are intentional and celebrated.
4 | Culture & Identity
The Power of Red
“Red is the colour of life, of people who have passion, who do things with love.” — José Azulay. UNOde50 red is instantly recognisable worldwide.
Gallery-Style Stores
Spaces feature cosmopolitan atmosphere with antique furniture and art by the creative team. More gallery than boutique.

9 | Frequently Asked Questions
Where is UNOde50 jewellery made?
All 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.
Can I resize my UNOde50 ring?
No. The multi-layer 15–20 micron plating makes resizing impossible without damaging the finish. Visit OD’s Jewellers for free professional ring sizing before purchase.
What does “UNOde50” mean?
“One of 50” in Spanish. Originally only 50 units of each design were produced. Today, limited edition pieces of 50 units are still released with each collection.
Is UNOde50 hypoallergenic?
Yes. All metals are nickel-free and skin-safe, manufactured under EU REACH regulatory compliance for skin-contact metals.
Why does my silver jewellery tarnish?
Tarnishing is natural oxidation when silver contacts air and moisture. UNOde50’s 15–20 micron plating resists tarnishing longer than standard plating. Regular polishing with a soft cloth restores lustre.
