This edgy double finger ring with a bold etched plate will quickly become a much loved statement piece. Made of 24k gold plated brass with a design inspired by Metro maps from around the world. Size: top: 4cm/1in long , 1cm /0.39in diameter : us - 8 / 18mm / 0.70in / general- medium I began the journey with ancient cultures from all over the world & used them to inspire the ethnic and aesthetic values of this collection. At the same time, I went through an industrial revolution of my own, traveling Metro subways lines across London, Moscow and New York. Inspired by my journey, I engraved these major rail lines on the seven basic metal parts that make up the complex designs in this collection. All of my items come beautifully wrapped in a gift box. Do not use perfume or water on this jewelry.
