Pi Necklace

I bought this necklace for a Christmas present for my daughter. I received it faster than expected, and it is a beautiful piece! I'm sure she's going to love it!


This necklace is great quality and beautifully made. I can't wait to give it to my math nerd daughter on 3/14. It's ok that I call her a math nerd because she gets it from me. 😉 I will order from them again. Oh yes, everyone also mentions the box it comes in - one word - AWESOME!


I’ve bought four different items already, and I am eager to find more people in my life for whom to buy things. These are beautiful, creative, well made, and FAR less expensive than I would have guessed for jewelry of this quality. Love it!

Pi to 35 Decimals Necklace - Silver

A very clever salute to Pi, and the perfect accessory to wear on Pi Day.

Who doesn't need a science necklace?

What a treat it was to find a lovely silver Pi to wear as a necklace. And even better, another piece of the necklace tracks PI to quite a few numbers to the right of the decimal place! I am not a mathematician, but I do love jewelry that tracks my passion for all things scientific.
