Spira Duonim is a handcrafted fossil ammonite necklace built around the image of a twin spiral — two movements unfolding side by side. The ancient fossil at its center was formed over hundreds of millions of years, carrying a natural sense of continuity.
The necklace combines natural pearl, agate, and amber with an ancient ammonite fossil. Each material brings its own tone and density, creating a balanced composition through contrast and harmony.
