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 live in Austria in central Europe. The necklace was delivered unexpectedly fast and I didn’t have any problems with payment or ordering details.
The quality of the necklace is just perfect and everyone, I show it to, is deeply impressed.
A dear friend of mine is going back to school, and I chose the brain necklace as a gift. She loved it! I really enjoy all of the fun, scientific jewelry for myself and my friends. Keep up the great work!
I have purchased several necklaces from Botique Academia. All of them are top quality, and have a great "feel" on my neck. The Acorn Necklace is the heaviest and largest of the assortment I have purchased. The chain is just the right weight to hold it, and the acorn pendant is unique and fun to wear.
I saw this necklace online and fell in love with it! It was out of stock and I had to wait 9 months, but it was worth the wait! It is even more beautiful in person than in the photos. (When it was out of stock, I asked to be emailed when it was available again. Boutique Academia was faithful and emailed! I ordered right away!) Very happy!
Whenever I'm looking for unusual, inspiring jewelry for gifts for my friends, I always come to Boutique Academia. I love their designs, the craftmanship is top notch and most importantly, there is inspiration in every piece which makes for a meaningful gift.
I recently ordered the Fibonacci necklace for my wife. She absolutely LOVES it! Boutique Academia made the whole process very easy & I will definitely order from them again. Service was very prompt and courteous, shipment arrived in a very timely manner and the quality is top-notch!
As a scientist and a nerd, I bought two earring sets, one of the Fibonacci Sequence and the other Particle Physics. I love them both. They are made well, and people keep stopping and commenting on them. So unique! I wonder which piece I'll get next. (-:
Really love this company and will definitely order from them again. Great customer service, fast order processing and delivery. VERY happy with both meaningful necklaces, Orion and Aries, that I bought.
A five star rating well deserved... Boutique Academia provides a great and efficient service and the Tardigrade necklace I bought, without any problem, is as beautiful as I thought... Love the concept !
fun and good quality stuff! At very reasonable prices!
i am a biologist who works as a chemist with a sister who is an engineer. I love finding jewelry and key fobs that represent what i do. i have been sharing the business cards that came in the box with each item with fellow STEM women. They are also rather geeked about this. YAY! it it about time someone did this!
