All ARK chewelry can be used by both kids and adults, boys and girls.  Some people, however, asked us for a more traditionally-girly shape.  Well as they say, diamonds are a girl’s best friend – and so ARK’s Diamond Necklace was born! This chewable bling is a great solution for anyone who needs to chew.  Use it as a safe alternative to chewing on shirt sleeves, collars, pencils, fingers, nails, etc. to help calm, focus, and self-regulate.
