Pi Pendant - Math Jewelry

Regular price131.00 €
Tax included. Shipping calculated at checkout.


This pendant is inspired by 'pi,' the mathematical constant equivalent to the ratio of a circle's circumference to its diameter. Used in the ancient world by Egyptian, Babylonian, Greek and Chinese mathematicians, pi is an irrational number that cannot be expressed as a common fraction. The constant wasn't represented by the Greek letter pi until the 18th century.

The pi pendant is a delicate 1.3 cm (0.5 inches) below the loop.

The pendant is 3D printed in solid sterling silver or 14K gold plated brass, finished with a 45 cm/18 inch long sterling silver or gold plated silver chain, and is ready for gift giving with a gift box, polishing cloth, and care instructions.
