A designer by training, a storyteller at heart, and someone who’s always been fascinated by the quiet power of what we choose to wear.

The original Growing Jewelry collection was my attempt to bridge nature and design. I crafted rings that held real moss, asking wearers not just to display them but to care for them.

At first, it was about playfulness and poetry. But as those little green rings made their way into the world, people reached out. And the questions they asked went far beyond moss.

Because jewelry isn’t just sparkle. It’s story, symbol, and self expression and it deserves to be understood as much as admired.

So, if you’ve ever wanted to know why a ruby means passion, or how to keep your silver bright, or what your great-grandmother’s brooch might say about the era she lived in you're in the right place.
