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.

Thanks for shipping this so quickly. I have already received list of compliments on the necklace
Leonardo da Vinci's Flying Machine Necklace
These necklaces are amazing and perfect for my purposes as bridesmaid gifts in my book themed wedding!
The necklace looks just as pictured. I plan on wearing it every year on pi approximation day. It is priced appropriately for the quality.
I gave this to a really close friend of mine because I thought of her as soon as I saw it. She absolutely loved it and it’s gorgeous. No regrets!
I was quite pleased with this necklace and my mathematics daughter who teaches at the college level was thrilled to receive this gift! Thank you for your creative math inspiring necklace.

I have received many compliments on the jewelry I ordered from here. I love it and will order again soon!
It was birthday present for my wife, and she loves it. Elegant, simple, and beautiful.
As the father of a STEM-minded daughter I discovered these folks Christmas before last. Now my wife is wearing a necklace from here as well as my daughter. I love that I can tell my own story to go with the gift(s).
I bought this for my girlfriend, and she wears it every day. Nice quality and very quick shipping.
The tardigrade necklace was a bit larger than I thought (from seeing the
photos), but that was just fine. It is quite beautiful and detailed. It was a
gift for my wife, and she was thrilled with it.
Scientifically accurate and great quality
My daughter loves her bracelet. It is so simple but lovely. Beautiful.
I love this piece. I love the idea behind it, how it expresses infinity. It is lovely. It is so unique and elegant.
My daughter like it! Please more subjects! Your shop is the best!
My sister is a professor so I got her this necklace for her birthday. She was thrilled with it and is enjoying wearing it. I have never been disappointed in a purchase from this company. Wonderful customer service and creative and beautiful pieces. Thank you!
I love this piece! I bought it because I love the gorgeous, intricate design but in real life you can tell it's extremely well made, too. It's the perfect blend of nerdy and sophisticated, which I aspire to embody (at least sometimes). I love everything I've bought from Boutique Academia and this is definitely a new favorite.
Shipping was faster than expected and product was of a high quality.
The brain necklace has great detail and the young lady who received it loved it!
Solar spectrum necklace; I ordered this for my daughter and she absolutely loved it. It arrived very quickly, packaged very safely and securely. I will definitely be making another purchase!
I was impressed with how fast my order was shipped, and it pleased me more when it arrived. It's exactly like the beautiful website shows.
Really happy with the quality and packaging. It just gave a little something extra to the buying experience. They loved the birthday gift. I am sure I will be buying more gifts in the future from you.
...my step-daughter suffers with low self esteem, always a fight to just nudge her along, in almost everything, she graduated high school and this May college, with a degree in a field she will excel at, for the first time she is looking forward instead of her feet, I saw the bracelet, it was for her. Her battle her success, a little token of respect, to let her know, her mother and I noticed.
Another fantastic product from a fantastic company. Always a hit as a gift.
Everyone loved their gifts from your pop up store before Christmas! Very reasonable in price too.
My granddaughter really loved the physics jewelry.
I absolutely love this necklace! It is lightweight yet durable and the stars are clearly imprinted on the necklace! One of my favorite pieces yet!
