About Xtellar

Xtellar is a Spanish jewelry brand, born from a dream — like many of my creations. I dreamt of a name: Estelar. At the time, I thought everything should be in English, so I turned it into Stellar, but with an X that felt more futuristic: Xtellar. Today, naming things in English feels a bit absurd to me, but I still feel deeply connected to my brand’s name.

Xtellar is my way of expressing myself, my creative space. Imagination, for me, is a joyful refuge where everything can change and reinvent itself. I want to share that universe with you through these small sculptures that take the shape of jewelry.

Behind Xtellar, it’s just me, Marta Callen, handling every detail: design, production, and everything in between. For now, it’s a one-person project, but I hope that changes someday.
