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.

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.
This necklace made a great gift for a recent grad and budding neuroscientist! Item arrived quickly and was as pictured; good size, quality, and detail.
Looks great. I bought it for a gift... but might keep it!
i love this necklace. it's beautiful and nicely weighted. so happy with it!
Love both pieces. My students really think I am a science geek now.
I absolutely loved the key chain. The craftsmanship was wonderful and shipping was fast.
The pendant has a nice weight to it, and it's the perfect size. Orion was the first constellation I was able to identify, and it remains my favorite. Very pleased to be able to have it near me even when it's no longer in the night sky.
Love it. Decent weight,good quality chain, appreciate the cristae, worn it every day since I got it.
I bought this for my girlfriend’s birthday coming up. When it arrived, I was pleased by its weight; it does not feel like lightweight, cheap construction so I’m not worried about it deforming if it gets dropped.
We gave one of our purchases, the atom necklace, to my daughters favorite teacher. She wore it the next day and her fellow science teachers all commented on how much they liked it. My daughter chose the blue nebula necklace for herself and loves it! We will definitely be back for more!
From a fantastic design, great craftsmanship, and quality materials this necklace is unbelievable. The best part is the center cover that pivots to reveal the interior of the virus. It is one of those necklaces that people just have to comment and ask about.
The T4 phage earrings are very comfortable, not heavy at all. I don't notice them until their heads brush against my neck... or catch on a scarf or sweater. (The collar whiskers are blunt but snaggy, easily dealt with if you're mindful of it.) (Dear Reader, I was not initially mindful.) I'm very pleased with them, and may have to get the necklace as well. A very fun find.
Maile was very responsive to emails and accommodated requests accurately and promptly.
My daughter absolutely loved the Brain Keychain that I purchased from you. She is a premed student and was so amazed as to the detail of the brain on the keychain. Will definitely buy from you again!
Bought this necklace for my math and science loving daughter. Not only was it the perfect gift but it arrived only 3 days after ordered and in a box too! Which I thought was nice but my daughter immediately noticed the science and math designs and loved the box too.
This is a very well-made necklace that can accessorize many different outfits. It is a subtle reference with elegant properties
I was looking for a unique gift for my friend who says she is a citizen of the Galaxy, The “ galaxy” necklace was perfect and she wears it all the time.
It was a Valentine's Day gift and a success! And the added emphasis on STEM for girls is fantastic
Thanks for replacing the broken atomic necklace for my daughter. Super service.
