In nature, the Nautilus shell is a naturally occurring example of the "Divine Proportion". In cross section, the chambers of the Nautilus shell vary in size at a mathematical ratio of 1.618 to 1, progressing upward or downward into infinity.

Over the centuries, this magical proportion has been humanly recognized as a universally pleasing composition, and is found often coincidentally, or planned, in art, music, nature, and physics - It is believed to disclose a golden harmony behind our wordly existence and physical laws. This jewelry piece is an exact proportional diagram and comes with one of our new ROLO style chains, a chain of vintage design with a handcrafted feel.
