Happy Glass Hearts are made with a press that has sentimental value to me. I bought it from Roberto Dona when I visited his workshop on the Island of Murano. Roberto is a third generation glass tool maker and does his grandfather proud. I enjoy holding the heart in my hand, like a worry stone. The meduim length is adjustable between 18 and 22 inches. The long chain is adjustable between 24 and 28 inches.
