ABOUT



Each MRSJ piece of jewelry is more than an accessory – it is a personal talisman, a symbol of identity and self-care.
Founded in 2020 by Martina Rozenberg Smira, MRSJ is a Prague-Barcelona-based artisan jewelry brand that draws its essence from the unique energy of these two vibrant cities. This combination of influences is deeply embedded in each collection, creating special pieces of jewelry that reflect the spirit of both places.
Each piece in the MRSJ collection is crafted with the intention of bringing strength, confidence, and style to its wearer. Inspired by a powerful energy, MRSJ jewelry aims to fill a missing piece within the soul, becoming a personal talisman for those who wear it. Our collections range from delicate, understated designs to bold, chunky statement pieces, catering to a variety of styles and occasions.
Every MRSJ piece is carefully designed by Martina, drawing inspiration from the people and experiences that shape her life. From inception, MRSJ has focused on small, thoughtfully curated collection drops, offering timeless creations that transcend seasonal trends and deadlines.
My passion is jewelry making, and therefore I create some collections entirely by hand. However, for certain pieces, I collaborate with suppliers from Spain who meet my standards of quality and design. These items are labeled as 'Design selection'.


The entire amount from the special collection (excluding VAT and shipping) goes to help the Ondrášek hospice, which cares for sick children and adults.
If you are looking for a piece of jewelry that will reflect your personality, protect you, or simply bring you joy, you have come to the right place.
Check out our collections - and don't forget about the special charity collection, from which the entire amount, excluding VAT and shipping, goes to the Ondrášek hospice.
Thank you for being part of my journey - your support helps not only to create, but also to help where it is needed most.
