The Sprial Signet is part of the 1.618 collection. 

The Golden Ratio (1.618) forms a spiral because when you divide a golden rectangle into squares, the corners of those squares trace a curve. This creates a logarithmic spiral that grows outward while keeping the same proportions. This type of spiral often appears in nature because it's an efficient growth pattern that maintains the same shape as it scales.
