Pi to 35 Decimals Necklace - Brass

5 items left

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 your choice of a leather cord with black ceramic beads, a cotton cord, or a gunmetal chain.

Like all constants should, this pendant ages well: in time it will develop a lovely antique patina. 

Perfect for:

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

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.
