Number 1. Meet Code, our enduring classic. Inspired by the original font from the Plaza Hotel room numbers found by Lisa Salzer in 2005, these handmade rings are cast in rich 14 karat yellow gold. All about symbolism, our Lulu Frost CODE number rings are special because they uniquely symbolize you. Expressing everything from your birthday or life path number to your anniversary, from your lucky number to how many children you have, these rings say so much in a subtle way. We love how the numerals layer and play off one another, allowing you to add more numbers over time or tell the whole story in one great stack.
