Our ‘Work in Progress’ hearts encourages you to embrace the process of being a work in progress. It’s a commitment, not an excuse: Do the best you can until you know better. Then when you know better, do better.” Maya Angelou These fair trade natural stone hearts are hand-carved with a machete by artisans in Kenya. Since these show the natural colors of the stone, some color variations should be expected. One can often see shades of cream, gray, pink, and brown in the hearts.
