The Giving Keys
The Giving Keys is a pay-it-forward company that intends for their jewelry to be re-gifted. Each key has a word that holds a particular meaning to the wearer. Then when the time is right, they will pass the key to another person that needs the word. Stories of the impact of each key can be found on The Giving Keys website.
