Ancient, mysterious, elusive, and beautiful -- pi symbolizes not only a number, but also the ongoing quest of science and math to approximate the universe just a little better. Wear a stylish and sophisticated piece of the eternal puzzle with this hand-stamped tie bar displaying pi to 10 decimal places.
Available in aluminum or bronze, it is sturdy enough to last a lifetime. (Note that hand-stamped lettering varies a little, so yours will be charmingly unique.)
I appreciate this more than anything, and I'll give it to someone special.
Happy Pi Day!
Purchased for my son as a gift. He absolutely LOVED it! He stated that it was a nice surprise and was crafted very well. We celebrate Pi Day every year. Boutique Academia offers some awesome unique jewelry items!
Quick, efficient, and exactly as shown on the photos.
I bought this as a gift and it wad a huge hit! Thanks so much for quick shipping and great quality! This is the second item I've purchased from Boutique Academia and I will again!

Love my necklace & got one as a gift for my neuropsychologist too & she absolutely loved it!! I'm a brain injury survivor so the details & meaning of what the brain is capable of is extremely important to me. I purchased these to celebrate my 2yr rebirth (anniversary) date of my accident.
I was looking to replace some older molecule earrings from a different shop for some newer ones made of better material. I made no mistake by purchasing through Boutique Academia! They look gorgeous and with myself being a chemist and working in a research and development lab, I get compliments on them constantly! I just have a hard time choosing which ones to wear! I will definitely be looking to buy more soon!
My new DNA earrings draw attention, especially when I wear my necklace of the same. Being so reflective, they catch the attention of admirers. Love wearing them. And the quality, forget imitations, these are superbly made. They just go with anything too.
I got these for my daughter’s 13th birthday and she loves them! She is considering spending her allowance on more of your beautiful jewelry. Thank you for giving her the chance to express one of her loves...math!
I love my tardigrade necklace. Many of the children I work with have asked about it, learned about tardigrades, looked for them, and in some cases found them, and then educated others about them. Fantastic!
I bought the serotonin molecule necklace as a gift for my little sister. It arrived quickly, and already presentable in a lovely box. My sister loves the necklace and wears it every day. Thank you for such an amazing product!
This necklace is just beautiful! I've been wearing it to work and everybody keeps asking me where I got it. It is just as beautiful as seen on the pictures and I love the binoculars detail. I expected it to take weeks for it to arrive in Norway, but I got it really quickly. Anyone who loves travelling or just the world in general should get this!
I love the necklace. Good quality, beautiful design and very nice packaging. It will be a high school graduation gift for my granddaughter who has been accepted toYale Univerisity on a full scholarship. She is majoring in Pure Math so can imagine how excited I was to find this website. No doubt I will purchase again from Boutique Academia and have already recommended it to friends.
