The irrational number Pi, approximately 3.14, is a mathematical constant representing the ratio of a circle's circumference to its diameter. Its use of the Greek letter Pi has been established internationally since the mid-18th century, with its symbolism derived from the Greek word for "region" (Περιφέρεια - Periferia in Greek, Π - Pi). When Greek characters are not available, Pi is represented by the Latin alphabet as "Pi" and is also known as Archimedes constant.

This Pi necklace/bracelet is an elegant piece of science jewelry, representing a real number that is widely used in mathematics, physics, and engineering to define the ratio of a circle's circumference to its diameter in Euclidean geometry.
