Alchemy, an ancient practice of transforming metals, except for us, it's a 'green alchemy' where the simplicity of a fine green agate baguette stone on 1.3mm band is a reminder that transformation can be found in the most simple of practices. With agate, traditionally known for its ability to convert negative energy into something constructive, this minimalist ring acknowledges virtue in 'simplicity' and the transformational beauty of the 'discreet.'
