The Tombola pendant was designed by Javier Hernandez who won David's jewelry design contest for May-June 2007. Javier descrbied the pendant in the following words: "Eternal motion of the physical and spiritual realms. The inverted axis on each circle represents that life's eternal motion is never random. Nothing happens by accident. Life's events are filled with purpose. There lies the meaning of life."
David chose this model because of it's likeness to the shape of the Torus Tube. The Tombola resembles a kind of a Black hole where all that is old perishes and turns into new. This is the universe's way of achieving cosmic forgetfulness, in order to unleash the potential for endless new possibilities. We are all created by the same process. When a star perishes, it transforms into a Supernova, which eventually turns into new stars and new life forms.
