If you need a variation that’s not available let us know and we will add it!
The 2 for 1s are always the small version of π.

This pi necklace comes in a little black velvet bag with one chain. We will add a silver or 14/20 yellow gold-filled cable chain in the chosen length, please specify if you want an extra chain or a silver chain for a gold ring (rose gold comes with a silver chain) and vice versa BEFORE your order.

Note: The plated variants are made of brass electroplated with 0.25 microns. It is an economical alternative to solid gold for occasional wear. For everyday wear, we recommend sterling silver or solid gold variants. Brass can react with your skin leaving a non-harmful greenish tinge with wear over time. To prevent this, you may consider coating the pi necklace with clear nail polish.

Dimensions:
Pi Big: 2.8 cm x 2.5 cm x 0.4 cm
Pi Small: 1.9 cm x 1.5 cm x 0.4 cm

Any math and science nerd will love these math and science necklaces! These science pendants also look great on 20 mm hoop earrings (let us know if you need inspiration).

About π

The number π (/paɪ/; spelled out as “pi”) is a mathematical constant, approximately equal to 3.14159. It is defined in Euclidean geometry as the ratio of a circle’s circumference to its diameter, and also has various equivalent definitions. It appears in many formulas in all areas of mathematics and physics. The earliest known use of the Greek letter π to represent the ratio of a circle’s circumference to its diameter was by the Welsh mathematician William Jones in 1706. It is also referred to as Archimedes’s constant. (From Wikipedia)
