Simply wear them: when you wish and as long as you wish; in full freedom. A single jewel or more jewels at the same time. (An idea to wear more jewels together: put all the jewels on a single string and tie few knots at regular intervals to keep the jewels apart.) "At times the Healing Jewels show some sign. It is their nature to work in this way: they can disappear or break... it is like a message from which we can understand they are helping, that one healing has taken place..." But it will not always happen: most of the times the jewel will stay with us forever!
