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.

Love my necklace & got one as a gift for my neuropsychologist too & she absolutely loved it!! I'm a brain injury survivor so the details & meaning of what the brain is capable of is extremely important to me. I purchased these to celebrate my 2yr rebirth (anniversary) date of my accident.
I was looking to replace some older molecule earrings from a different shop for some newer ones made of better material. I made no mistake by purchasing through Boutique Academia! They look gorgeous and with myself being a chemist and working in a research and development lab, I get compliments on them constantly! I just have a hard time choosing which ones to wear! I will definitely be looking to buy more soon!
I gave this as a gift for my bridesmaids and they all loved it! They're beautiful and part of the proceeds goes to a wonderful non-profit!
I am very happy with my necklace. Postage to Australia and service in general was outstanding.
My new DNA earrings draw attention, especially when I wear my necklace of the same. Being so reflective, they catch the attention of admirers. Love wearing them. And the quality, forget imitations, these are superbly made. They just go with anything too.
I got these for my daughter’s 13th birthday and she loves them! She is considering spending her allowance on more of your beautiful jewelry. Thank you for giving her the chance to express one of her loves...math!
I love my tardigrade necklace. Many of the children I work with have asked about it, learned about tardigrades, looked for them, and in some cases found them, and then educated others about them. Fantastic!
I love my necklace, it’s unique, well made and is very comfortable to wear, it’s sits nicely and gets loads of attention! I love it and would definitely buy from Boutique Academia again!
I love this necklace! I have this and the Orion one. The quality is superb and the shipping was ultra fast!
I gave this to my 14 year old granddaughter. She is an avid reader and she loves this. It looks very nice and she wears it often. She loves it.
I LOVE this necklace! As an anthropology minor it was a nice touch. Very fast delivery.
This beautiful Orion pendant takes me back in memory when my father was teaching me the night sky.
Totally love the sweet (fully functional) abacus pendant. And my wife loves it, too.
Thanks!
Beautiful necklace. Arrived quickly and in expected condition; will make a fantastic gift for my lab assistant!
My favorite thing about this necklace is that I could order it with a longer chain. The chain itself is very study - not cheap at all. I love playing with the spectrum medallion whenever I wear this.
I purchased from Boutique Academia as a gift - and it arrived in a lovely little gift box and in perfect condition.
I love my "happy mood " necklace. I receive so many compliments.
Great gift for those into biology and chemistry. Very pleasing to the eye and fun too as an interesting conversation piece
This is a great necklace and just as described. I will really enjoy it. I will shop here again.
Bracelet is beautiful and my daughter loved it. A great way to remind her how proud we are of her. Fast shipping and quality merchandise. Girl Power!
I wore this tie bar to an interview today and was able to use it as a talking point when we discussed my qualifications. It is made of a great quality material and looks really good.
My ph.D daughter loves her DNA earrings. I found this site late and was so impressed that the earrings arrived quickly and before Christmas! Looking forward to finding more unique items.
Must have for your science geek!
Thank you so much I got this for my sister-in-law who is a librarian and she is madly in love with it! I am grateful that you gave me such a special gift to give her.
I love the quick shipping, the cute box and the quality of the merchandise!!! Love it!
I ordered three necklaces. They were all beautiful and wonderfully unique. My two best friends and myself will wear them proudly.
I appreciate this more than anything, and I'll give it to someone special.

Lovely piece that can be worn with jeans, shorts, summer dress or just anything. I get lots of compliments on it. I had it engraved with the date we had the eclipse on the back. Great keepsake.
I bought the serotonin molecule necklace as a gift for my little sister. It arrived quickly, and already presentable in a lovely box. My sister loves the necklace and wears it every day. Thank you for such an amazing product!
This necklace is just beautiful! I've been wearing it to work and everybody keeps asking me where I got it. It is just as beautiful as seen on the pictures and I love the binoculars detail. I expected it to take weeks for it to arrive in Norway, but I got it really quickly. Anyone who loves travelling or just the world in general should get this!
Such a beautifully crafted piece of jewellery...and so will finished. Bought this for my niece. She loves it!
The earrings arrived in good time and were exactly as ordered. My daughter loved them. Others thought they looked like trees, which is exactly what neurons should look like. Thanks!
I love the necklace. Good quality, beautiful design and very nice packaging. It will be a high school graduation gift for my granddaughter who has been accepted toYale Univerisity on a full scholarship. She is majoring in Pure Math so can imagine how excited I was to find this website. No doubt I will purchase again from Boutique Academia and have already recommended it to friends.
The necklace arrived very quickly and is gorgeous! A gift for my son's Biology teacher. I'm sure the other teachers will be jealous!
Really pretty, perfect length. I've been looking for a necklace that has a saying that resonates with me and this is it. The Mobius design just adds to the meaning. Very happy I purchased!
Bought the bracelet for my daughter - she loved it and it reminds her of who she is and wants to continue to be! Great service and unique products!
