Altitude BoutiqueSimple Happiness Serotonin Molecule Necklace, Serotonin Neurotransmitter Necklace, Science Jewelry for Science Lovers (Silver, Gold, Rose Gold)

Awesome jewelry, unique and high quality for price. Seller very responsive and personable. Would recommend and plan on purchasing more in the future.

I bought myself a gold one and my daughter a silver one. Very good quality and was delivered on time. I love this necklace. I've wanted one for a long time!

Good craftsmanship and seems durable! Sadly I am allergic to the material and develop irritation when I wear it.

I bought this as a birthday gift for my fellow chemistry-nerd friend as she has the serotonin tattoo and she absolutely loves it. She wears it all the time except while showering.

I love this product! I used it on a very humid area and the gold plating is still intact! To be fair I only used it once. I hope it stays gold! One thing though, 18 in is a little bit small for the wide circumference of my neck, would definitely given it a 5 stars of they offered longer than 18in.

Arrived quickly, and is well-made. I even sleep in it and have had no issues with tangling, twisting or damage. Nerdy people always stop me to ask bc they recognize the molecule chain 😊

I love this it’s lasted so long I wear it every day and night and the seller is so sweet

Was a gift for my younger sister who is aspiring to be a Nurse. She loves it. Its simple and not bulky or heavy. She wears it all the time.
