Ravena: The Ravena motif is inspired from archeological evidence remaining from Celtic tribes that lived in Central Europe, 2400 years ago. It shows the spiral, which has always symbolized growth, gathering into a circle. To us, this design represents creative action. We see similar lines in the root of a plant, eddies of a river, or any circle of communities amassing energy to make something new. Our Ravena design jewelry is handcrafted from 100 percent recycled metals, ethically sourced stones and gems wherever possible and comes with a lifetime guarantee against defects in materials and workmanship. These heirloom quality pieces are both socially responsible and eco-friendly. Our artisanal Celtic jewelry pieces are available in gold, gold over silver and sterling silver.
