Wear the most beautiful of the mathematical constants. This pendant consists of two engraved and shaped brass disks. The top disk displays the pi symbol, while the bottom disk has pi to 35 decimal places. The larger disk is ~ 1" in diameter. The pendant hangs from an adjustable black cord. Like all constants should, this pendant ages well: in time it will develop a lovely antique patina. See also our Silver Pi to 35 Decimals Necklace.
