Our Story
ALÚ is a jewellery brand inspired by lightness, strength, and transformation. Its name comes from the Irish word alúmanam, paying tribute to Ireland, where the brand was developed.
ALÚ brings together Brazilian creativity and an Irish perspective through jewellery that celebrates individuality and thoughtful design. Our collections combine pieces created in collaboration with a Brazilian designer, curated by me, with original designs I develop myself — all reflecting ALÚ's evolving vision and distinctive aesthetic.
Designed with intention. Worn with confidence. Made to express you.
Meet The Founders
Mariana Simizu – Co-Founder & Creative Director
Mariana Simizu is the Co-Founder and Creative Director of ALÚ Jewellery, bringing together her background in business leadership, personal branding, and a passion for intentional design. With a career centred on people, growth, and purposeful outcomes, she brings both a strategic and creative perspective to building the ALÚ brand.
Passionate about empowering women to embrace their confidence, visibility, and individuality, Mariana believes personal style is a powerful form of self-expression. This philosophy shapes her approach to ALÚ, from developing her own jewellery designs and curating pieces created in collaboration with a Brazilian designer to shaping the brand's collections and creative direction.
For Mariana, jewellery is more than an accessory. It is part of how a woman expresses who she is, how she feels, and how she shows up in the world. Through ALÚ, she brings this belief to life, creating contemporary, thoughtfully designed pieces that celebrate individuality, confidence, and the stories that connect us.

Our Materials
At ALU, material choice is intentional.
We work primarily with recycled aluminium and stainless steel, modern metals selected for their strength, lightness, and durability.
Recycled aluminium is lightweight, corrosion-resistant, and infinitely recyclable. It allows us to create bold forms without unnecessary weight.
Stainless steel adds structural integrity and long-term wear, resisting tarnish and everyday use. In selected collections, we combine metal with leather, textiles, and stones, introducing contrast, texture, and movement.
We don’t use disposable base metals. We design pieces made to last beyond seasons and trends.
Modern materials, conscious design.
Our Collaboration with Ana Solci
ALÚ collaborates with Brazilian jewellery designer Ana Solci, founder of Alumina, bringing together her design expertise and Mariana's creative vision for the brand.
With nearly 20 years of experience in the fashion industry, Ana creates contemporary, artistic jewellery using recycled aluminium. Together, we select and curate pieces that align with ALÚ's aesthetic, celebrating sculptural forms, thoughtful design, and the beauty of the material.
This collaboration brings Brazilian creativity and craftsmanship into ALÚ's collections, while allowing the brand to evolve through Mariana's own designs and creative direction.
