“Narrow” size is shown in first photo. “Wide” size is in third photo - it aligns with your collar bone. Chose your length (normally around 18” works & I leave room to make longer or shorter!). Also, include in order which stone you would like. I place the stones in the spot where the shoelace connects to the chain. I love moonstone as it is great for healing (inner strength & soothing for emotions, shown in pic) - but will do any stone of course!
