I love the Atomic necklace. New favorite piece of jewelry.
I bought this keychain and I’m so happy with it. The quality is amazing and it’s exactly what I was hoping for!
Quick delivery to France. I received compliments from people who didn't recognize the tree of life and I enjoy wearing a scientific pattern with a graphic look !
So glad I made this purchase- it’s perfect. Quick service and fast arrival in the UK too. Thank you.
Love this site and its super unique science products. I bought the Water Bear necklace as a gift for an employee and she loves it. Can't wait to place my second order!
This necklace has the speed of light in a vacuum expressed in meters/second.
The finish of the necklace is very good and my niece who is at university loves it.
Perfect gift for the occasion. Good reminder that you’ve made it through and can keep facing those challenges. I hope the newly minted Dr likes it.
My daughter in law was absolutely thrilled with her Tardigrade necklace and put it around her neck as soon as she opened her present. She loves everything that Tardigrades represent! Tardigrades are amazing triumphant fellows! Go Tardigrades go! And, daughter in law's too!
P.S. And, her Tardigrade necklace looks lovely on her too!
As a children’s author of STEM picture books these earrings make the perfect addition to my outfits when visiting classrooms. The jewelry created by Boutique Academia is stylish, unique, and best part hypoallergenic.
Bought two Tardigrades for my girlfriend. She loves them very much
Quite nice very trendy my brainy granddaughter will love them
So excited about this jewelry! It's so well made and heavy and beautiful. I am obsessed.
As a molecular biologist, accuracy is important to me and this necklace is accurate and beautiful. Only complaint is it’s a little short but I got an extender and that was solved. Overall great product.
