Avogadro's constant: "the number of elementary entities per mole of substance". It's a big number...which is to say, there's a lot of stuff in the universe. Wear a piece of it with this hand-stamped tie bar.
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 ordered a tie bar and received it only 2 days later...in plenty enough time for our last day of school gift exchange! The gift was well received!
Avogadros constant tie bar
Other than needing a spring instead of straight across, keep having to adjust. It is great, conversation starter for sure!!!
Avogadro would be proud
Excellent product, ordered from the UK arrived less than a week
Great Tie Clip
Bought this for my husband as a present in the gold/bronze color. It is a gorgeous color and we were both very happy with the quality of the product. He loves it. It arrived quickly and in a beautiful box. I would definitely recommend this company and product.
Excellent gift idea!
Thank you for the wonderful ideas you design. They make great gifts and are so appreciated by my friends.

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.
