Avogadro's constant: "the number of elementary entities per mole of substance". It's a big number...which is to say, there's a lot of stuff in the universe. Wear a piece of it with this hand-stamped tie bar.
Available in aluminum or bronze, it is sturdy enough to last a lifetime. (Note that hand-stamped lettering varies a little, so yours will be charmingly unique.)

I lost an identical charm and decided to order a replacement from a different company because of the price. It came in a super cute box. My daughter is studying to be an engineer and the little angle with wings made of formulas was a bonus. I see they have all sorts of STEM inspired jewelry! Only thing I would change is shipping method/speed.
The Orion necklace was a gift and the recipient absolutely loved it. She loved the quality and was very complimentary of its uniqueness and beauty. A big hit. Would definitely buy again.
The necklace is exactly as expected. The chain is a good weight but not too heavy. Very pleased with the product.
My sister loved the gift :) thank you!
I ordered this as a Valentine's Day gift to ship to my wife, who is away from home as a travelling nurse. She was ecstatic!
She absolutely loved the earrings! They have been on her wish list for years and our first Valentines day together was special thanks to these!
A very original idea to make jewellery from virus and antibodies. The pieces are very well made and the whole piece make a very fetching visual attraction.
Gorgeous earrings for lovers of phylogenetics! The perfect accessory for my PhD graduation!
I purchased a pendant necklace recently. I am absolutely charmed with it - the quality is top-notch and it looks beautiful. The necklace was delivered in a very timely fashion (especially given today's problems), in a sweet box that I will re-use at some point. I couldn't be happier with the value of my purchase.
Fine quality, excellent service. Great selection
