Romany Gypsy's hold stone's in special shapes as sacred objects & believe that they are especially lucky.
A stone shaped like a horse for example ensure's luck in horse trading & gambling. A stone heart means luck in love & so forth.
What I love about every stone that you pick up is that they are as unique and individual as people are.
Every time I'm out on the beach now I just can't resist finding stone's with special meanings.
