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.

  • Mathematicians or math aficionados
  • Engineers
  • Architects
  • Rational and irrational people alike
  • Anyone cool enough to celebrate Pi Day

Pi to 35 Decimals

I received the 2 Pi necklaces sooner than expected. It was my birthday and a coworker. The box was quite unique and wrapped beautifully. She posted this on face book with many likes. Since I work in cardiology the anatomical heart necklace will be my next purchase.

Not only was the necklace I ordered great quality but the presentation was nice as well. It was both a beautiful necklace and packaged ready to give as a gift. My daughter loves receiving it as a gift and now wears it daily. Thank you.

Great Quality

I purchased this necklace to sew into a bridal bouquet for a couple getting married 3/14/15. The quality of the necklace is great and the cost was very reasonable!
