I can’t say I understand the science entirely, but the gems emit some sort of “magic chemical” that is all natural of course which is an analgesic or relieves the pain. So, without harming your baby it is basically absorbing their pain! Voila!

The necklaces usually range b/w $15-20 and they are worth EVERY penny!!

Check out these reviews I found on amazon:

“I was skeptical to start… but I have noticed a huge difference in my son when he has it on. He doesn’t drool as much and isn’t as cranky. It also just so happened this came right after he got hand foot and mouth and was refusing to eat because he had swelling and blisters in his throat. I put the necklace on and 2 hours later he was eating ( i think it took the swelling in his throat down)… coincidence or not I believe in this necklace!” — A Newman

“I was definitely a skeptic when I came to Amber teething necklaces but with my son being 6 1/2 months old and still constantly crying all day & all nightI had to give it a try. I was willing to try anything at this point. It took a few days to start working and then all the sudden he started going to sleep on his own he didn’t have to be patted on the back till he fell asleep… he just fusses a teeny tiny little bit and goes to sleep. sometimes all through the night! This didn’t happen until about four days after wearing this necklace. That’s not a coincidence! I don’t know what kind of magic voodoo this thing holds but I’m all about it. It’s insane. Absolutely recommend this!! Oh and yes, it’s exactly as pictured and no, it has not been a choking hazard. He doesn’t even take knowledge that he has it on I really don’t think he even notices he has a necklace on. Two thumbs up!” — OKrr
