The night sky is filled with wonder, beauty, and history. Originating in Babylonian astronomy in the 7th century BC, the zodiac was used mark the progression of months in the calendar for millennia. During the Hellenistic and Roman eras, the Babylonian star catalogs were adopted into Greek astronomy, and the signs began to acquire special meanings. These constellation pendants take a new, astronomically accurate approach to the zodiac... like birthstones of the sky. Each engraved black onyx disc displays the constellation and background stars precisely, to as low a magnitude as could be engraved. The bail is antique silver-pewter, and each 1-inch diameter pendant is hung from an 18-inch snake chain. Whether as a birthday gift or something special for yourself, these necklaces are unique and unforgettable!
Perfect for:
Don't know which constellation to order?
There are a variety of zodiac systems. Generally speaking, the Ptolematic (Tropical) zodiac is the most widely recognized. The Hindu sidreal zodiac takes into account precession of equinoxes. In 1930, the International Astronomical Union weighed in on the issue as well.

This Pi necklace is absolutely perfect for my science-minded granddaughter. She has been memorizing Pi and she's delighted with it.
First, the Orion Constellation necklaces were just what I was hoping for a special event. The pendant looks exactly like on the site, soft silver color with just slight texture. The cords are adjustable. The order came quickly, each necklace came nestled in a gift box, ready to present. Second, the customer care was what we all hope to find and much more. I had a few special requests and she called immediately to make sure I would get what I needed. Very pleased!
Very well made; good quality. I get many compliments on it.
I love my Fibonacci necklace. It’s fun. It’s made well. And I love when someone asks about it. I’ve already placed another order for more jewelry. Thank you!
The necklace was a present for my daughter who has studies maths. She loves it and i was impressed by the selection of the shop.
I ordered the heart necklace for a graduation gift for my daughter. It is beautiful and very good quality. She loves it.
Boutique Academia was very helpful with some shipping issues - my package arrived open with one item missing. When I contacting them about it, they responded promptly and sent me a replacement item. The necklaces I bought are great and will be perfect for the upcoming school year!
Greetings from Calgary Alberta Canada!
Want to thank you guys for hitting my STEM spot ;)
Reasonable price and construction for jewelry with a message! Particularly apropos is the virus and antibody necklace! I wear it as a sign of trust in science in this time of COVID 19! To quote Dr. Fauci-“it’s a case of when - not if” ( for a vaccine)
Take care
Stay safe
Be kind

Bought this as a gift for my daughter and was impressed with the quality. Shipping was quick and the necklace arrived in great condition. Would definitely place another order in the future!
Delighted with my purchases. The adjustability of the Pleiades necklace is a real plus, and the chain on the dopamine necklace appears surprisingly high-quality, considering the low price.
Gave this necklace as a gift to my niece who is studying biology and she loved it! I was so happy to find someone who was selling these unique gifts.
My wife, the scientist, loved the earrings that I purchased. It was the perfect gift. And the service was excellent too.
Gave the pi earrings and carbon atom earrings to my girlfriend. She completely dorked out on both designs. Easy order. On time delivery. Product exactly as promised.
Much nicer than I expected. Purchased for a young lady who just graduated with a Bachelors degree in mathematics. I haven’t heard if she likes it yet, but how could she not?
I ordered the sloth tarigrade necklace for my daughter,,,,,it was shipped & received very quickly. She loved it & so did i!! Would definitely order from Boutique Academia again!
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!!!!!!
Nice looking, Gift for graduate. She thought it was cool
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
I’m very happy with them! They look exactly like a real heart.
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 bought it as a farewell gift for my boss who is an immunologist that works on vaccines, and SHE LOVED IT!
Beautiful detailed brain earrings. Just the things to divert the zombies! No, seriously - they're beautifully crafted and fun!
Bought this for my girlfriend for her college graduation. She loves neuroscience and she loved it!! Thank you so much!
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!
What an original business. Our niece is brilliant in the sciences. Honestly, she will find a cure to some disease! The necklace we chose was perfect for her! “She Who Dares Wins” So true...
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.
I LOVE MY NECKLACE!! It is cute and fun and educates my kids.
