Speed of Light Necklace

5 items left

The speed of light is a fundamental constant of the universe. It represents a core principle of physics, astronomy, and our understanding of reality. Meter by meter and second by second... whatever your goals are, may light to inspire you to push forward and give your best!

This pendant measures 1.5 inches in length and is made from platinum or gold-plated steel. It comes on a sterling silver or gold-plated chain, in your choice of a 16 inch or 18 inch length. Choose 16 inches for a short, layering-style necklace, or 18 inches for a standard-length necklace. [As a note, we asked an ultra-marathoner friend to try it out for us... She reported it to be both sturdy and so comfortable she forgot she was wearing it.]

Perfect for:

  • Astronomers, physicists & science enthusiasts
  • Runners & athletes
  • Ambitious, high-energy achievers of all kinds

Speed of Light necklace

My granddaughter loves her necklace and I was impressed by the "speed" of shipping and quality. Happy to have found a science themed website!

The speed of light

This necklace has the speed of light in a vacuum expressed in meters/second.

The finish of the necklace is very good and my niece who is at university loves it.

...still didn’t receive it

Tracking: its still in LA since Jan. You did your part in sending out the order almost immediately, but covid-chaos is the impediment I imagine. I’ll be happy to review - I’m sure it’s beautiful. Hope all’s well at you end😘

Gorgeous! And I received it ultra-fast

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!!!!!!

Speed of light Necklace is so worth it!

I love this simple bar necklace. I love to wear my geekiness understated at times, and this is such a great way to do that! It's the perfect size, it's clear to make out, and I just freaking love it! I haven't seen anything else like this online, and the gift box was so fantastically cute. Definitely will purchase more from this shop.
