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.

I want to wear it to a Job interview. I saw it on The Big Bang Theory television show.
I wish every company you make purchases from on the internet offered the same experience. But then Boutique Academia would still find a way to outdo itself.
My necklace is darling. I wear it all the time. I haven’t worn it in the shower as I know better but it is easy to forget it’s on my neck, since it is so comfortable.
The only thing I wish is that they offered a Rose Gold option. 99% of the jewelry I wear is rose gold (rings, earrings, bracelets) so I’d get a rose gold necklace of the same kind in a heartbeat.
However, that’s my personal preference and clearly it hasn’t prevented me to adapt for sake of wearing something special.
If you’re on the fence about your purchase, go ahead fearlessly, their system will notify you of every step along the way! Even when your item is already in the mailbox. Bravo!!!!!!
I love the golden ratio, and couldn't resist these earrings (even though I really shouldn't have been spending the money right now). Sadly haven't had the chance to wear them much (dangly earrings + ear mask don't play nice), but I've tried them on. Nice and light, super cute, and even came with a cleaning cloth. <3
When I saw the image of a waterbear ambling across a cord in a sloth-like hanging posture, I knew I had to get it. So much more fun that seeing one with a ring screwed into its back! ;) When it arrived I had to take pics and post on social media, and my biologically-inclined friends filled the comments with appreciative prose. I really appreciate the accuracy of the proportions and even the limb attitudes. Very very well done. A+
I not only enjoyed the uniqueness of the products, they had very good quality. I had problems with the delivery service but Boutique Academia took care of it and helped me. I personally liked the quality and aesthetics of the molecule shaped earings more than the necklaces.
Hello. I ordered 2 necklaces; a Tardigrade necklace and a molecular necklace. They came very quickly. I really, really like them! The Tardigrade necklace is quite the conversation piece. It is so unique. The molecular necklace, I got for my niece. She loves it. She shows it to everyone. Thanks so much and keep up the good work!
I purchased speed of light necklace and Fibonacci earring for my daughter, who is a university student majoring in physics, she loved it. The jewelry is good quality and very well made, and the items were nicely packed and showed up in my mailbox quickly. I am so glad I found this source for unique gifts for my STEM friends! I am a physicist myself, and I hope the selection of physics-related items will grow, so I have gifts for all my physics friends.
A friend sent me the tardigrade necklace as a gift, and I was pleasantly surprised and pleased with the quality and solid heaviness of the tardigrade pendant. I love it so much I decided to pay it forward, so ordered another one to send to another tardigrade-loving friend, and she loves hers!
An adorable little badass you can carry with you to find your own resilience when you need it most. Smaller and easier to wear than the vertical one, with satisfying little toes to play with as you gaze into the abyss.
They were a birthday present for my niece who is an architecture student. She knew what they were immediately and she loves them. It was really nice to find a place devoted to jewelry that represents the sciences and professions. Things that have special meaning to those who try to find order in the world.
I have purchased the black hole necklace and earrings, Fibonacci necklace and earrings, and two tardigrade necklaces (my 6 year-old son loves tardigrades, we each have one). They are all beautiful, well designed, and better quality than the price might suggest. The earrings are light weight and comfortable and the necklaces are thoughtfully designed. I will definitely be purchasing more jewelry from them.
I absolutely love my Ad Astra Per Aspera Necklace from Boutique Academia. I've worn it nearly ever day since receiving it. The leather cord can be easily adjusted without removing the necklace and both the cord and the Ad Astra Per Aspera pendant are great quality and will hold up for a long time.
As a women working in a STEM field, I love that a company like Boutique Academia exists, for my sake and also for young girls and women in these fields. Thank you for making these beautiful pieces! I already have my eye on several other items.
