A very large long (1 and 3/4 inch) oval Lapis Lazuli bead is the plumb of this pendulum. It has a speckling of tiny Pyrite flecks in it. Lapis has long been identified with royalty, honor, wisdom and truth. This grade of Lapis Lazuli is becoming rarer and more expensive. I will keep these in stock until I run out of the beads. The length may vary; as I construct each pendulum I ask it how long it wants to be.
