Anything in your life, is possible.

Xander uses semi-precious stones in his jewellery and home accessories and finishes his pieces with either 925 sterling silver or 14k gold plated components and findings. All the jewellery he produces is also nickel-free. (he is also allergic!)

The brand, after his own name, Xander Kostroma®, launched in the Fall of 2018, is now stocked in 500+ independent boutiques worldwide. His collection is also available online from British retailers Freemans.com, Lookagain.co.uk and NotonTheHighstreet.com.

Xander firmly believes that: Anything in your life, is possible! ...no matter what your background, you just need to focus on what you want, believe you already have it, and you will achieve it. 

Sounds interesting?!

Xander is based in Lisbon (Portugal) and from his home studio all samples are created. Once a design is finalized, the sample is photographed and emailed to Lydia. Lydia is based in Handan City (China) along with her 2 assistants Lily and Pinna. The women, led by Lydia’s expertise, hand-make everything for the brand while their children are asleep in bed. Once production is finished, the goods are shipped to the warehouse in Swansea (Wales) where it’s from this location that all orders are shipped. Amy models from around her home and garden in Northamptonshire (England) while Ria shoots from her studio in Norfolk (England).


Xander was born on the 7th of April 1987 into a single-parent, working-class family in Swansea, Wales. After a strained relationship with his mother, he eventually found himself homeless at age 16. Xander “sofa surfed” for some months before finding a job working nights as a pot washer at a local restaurant. He eventually moved into a small bedsit along the seafront while continuing his studies at secondary school. A year later, aged 17, Xander successfully secured a job working weekends in the coffee shop at M&S which brought some stability into his life. He also moved into his own apartment in the city centre.

Management soon recognised his potential and promoted him to store Visual Merchandiser. It was at M&S, that his interest in jewellery began. Aged 20, Xander left to create his first company selling ex-High Street clothing online which he ran for 2 years.

About Xander Kostroma

His interests continued...

Aged 22, Xander decided to return to work in retail. He successfully applied for a role as a shop manager for Cancer Research UK in Neath. It was in this position that he gained a deeper understanding of management while overseeing a team of 30+ volunteers from different backgrounds and with various needs.

Xander worked for the charity for almost 2 years until 2010 when he moved to Manchester for a role in buying & merchandising at JD Sports Head Office in Bury.

In early 2012, Xander was approached by the recruitment team at VF International, in Switzerland. He passed the interview and emigrated to the Italian-speaking canton "Ticino" to work at the European Headquarters for the luxury denimwear brand 7 For All Mankind. Xander was immersed in the Italian culture, he learnt to speak Italian and spent most of his free time travelling around Northern Italy. Although Xander enjoyed his time at VF, he felt like he could no longer grow, so in late 2013 he handed his notice to work freelance.

In early 2014, Xander returned to the UK for 3 months to work in a showroom located on Great Portland Street, London. (Ironically, it was for a brand that he used to buy while working in buying & merchandising in Manchester). It was during this time, at the brands' showroom, that he was offered a license to produce jewellery on behalf of their label.

At the end of the 3-month contract, Xander returned to Switzerland and began to put together a range of bohemian-inspired jewellery for the brand.

The collection launched 6 months later and was received well. The range was sold at House of Fraser and ASOS online. It was stocked in almost 50 independent boutiques in the UK and EU as well as further afield at Zoot (Czech Republic), Modcloth (USA) and Zando (South Africa).

    Xander Kostroma Fashion Ltd

    In early 2015, Xander founded his company Xander Kostroma Fashion Ltd. He continued to work under license until early 2018 giving his notice to concentrate on his own brand, simply called; Xander Kostroma®. 6 months later, Xander launched a small capsule collection of earrings and recruited an international team based between Switzerland, China & the UK. Over the course of the next few years, the collections expanded into necklaces, bracelets, pashminas, and homeware.

    During the 2020 global pandemic, Xander left Switzerland for Portugal. After some months of exploring the new country, he decided to stay, setting up a home in Lisbon which is where the brand is managed.
