DAOSHANG925 Sterling Silver Serotonin Necklace Caffeine Molecule Pendant Necklace Gifts for Science Student Coffee Coffee Lover

This is a REALLY cute necklace, and I have gotten a ton of compliments.. that being said, the only drawback to this necklace is that the dangling part tends to twist up, which means by the end of the day you feel like it's tight.. it can easily by fixed by taking the necklace off and twisting it back, but it's a little annoying. Other than that, GREAT necklace, does not look cheap.

The recipient loved her "smart" jewelry. It was surprisingly small though and the chain appears to be quite delicate. Definitely a "special occasion" jewelry due to that fragility, but this was intended to be an everyday item. 4 stars due to that misconception on my part, but an image with a size scale reference would have been nice in the product. Still a lovely piece!

I love the necklace so unique. I am always so scared to order jewelry from Amazon because I am scared that it would look cheap or that the reviews certain products are fake, so it’s hard to trust anything online but I really love it and glad I brought it.

I think this is hilarious especially because it’s so intelligent ! It was on a birthday wishlist 😊

Love this little chain. It is a very small delicate chain. Ot sits high up on the neckline and it is good quality. it came package so the chain would not get tangled but it was in a gift box that had it displayed

I love that there is an extender option and I can pull the chain to make the caffeine molecule shorter or longer. Tons of compliments.

A little smaller than expected. Slightly magnetic, so a bit skeptical it is pure silver, and the seller said it was rhodium plated which is most likely not. No certifications or anything either. Still, the necklace is cute and I hope it lasts until graduation.

A bit smaller than excepted but very nice.
