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.

The articles are just as I expected, the delivery really quick. Nice!
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.
Highly recommendable!
This necklace is so pretty. Worth every penny, have been looking at this product for years and I'm so happy that I got it. I purchased the longer chain length and am so glad that I did.
I bought this necklace for a Christmas present for my daughter. I received it faster than expected, and it is a beautiful piece! I'm sure she's going to love it!
This is one of my favorite necklaces from Boutique Academia. I love the feel of it on my neck. The tiny coffee cup and saucer keep it fun. A bit of whimsy with the science-perfect.
My wife absolutely loved it! She was so surprised and did not know there was such a website to cater to math geeks. Thank you.
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.
Looks very nice and is good quality, I wish the necklace itself was not as long, but overall pretty happy. Would recommend👍🏻
Pendant is fine and what I expected, however very disappointed that the necklace is broken after wearing for a week.
Beautiful set! My "science teacher" daughter will love them!
I purchased the Lapis Lazuli necklace as a gift, and the quality of this piece is outstanding. I am sure the recipient will love it.
Beautiful! It is really stunning, and will be a perfect present! And the beads move so it can work!
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!
We have been waiting for this to come back in stock and it did not disappoint.
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.
and she received many compliments about it from her peers
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.
It is so pretty! People notice and comment on my necklace whenever I wear it.
My girlfriend and I are great fans of the Tardigrade. She was thrilled to get such a great pendant of our tiny hero. Thank you Boutique Academia!!!
I love the Black Hole Necklace! It is so awesome to have a piece of history to wear. It is very distinctive.
I was thrilled to find Boutique Academia which has an amazing collection of unique jewelry reflecting the beauty of our biology and environment. Good and responsive service as well!
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 !
i got several constellations that i know exactly fit each of my friends. fantastic find. i'm very pleased with the results.
I bought this necklace for my daughter who has a PhD in neuroscience. It ties in wonderfully with her research.
Serotonin, Dopamine, & Acetylcholine Necklace
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!
I bought a Serotonin+dopamine+acetylcholine necklace for our colleauge when She stopped workin in our company. It is so lovely and she really appreciated it.
Just love the earth from moon earrings--always one of my favorite pix--I have it on the wall at home--now I can wear proudly on my ears!!!
Necklace was exactly what I was looking for -- very well made, chain was perfect length. Seemed like I received it within 48 hours of ordering... I think that's right. Anyhow, many thanks!
My wife is the head of biology at a biotech company, and she squealed in delight when she opened this. She has already worn it several times in the last two weeks and her colleagues have loved it too.
I bought this for my author friend as a graduation present and she loves it! It's so unique, pretty and well made.
