This unique Bearing-Balanced™ Fluorite pendulum is designed by George Goodenow, this pendulum is BEARING BALANCED™. That means the pendulum chain rotates and swivels on a bearing that is inserted into the top cap(chamber cover). This results in a balanced swing that keeps the pendulum point, or bob, always aligned with the chain while swinging . This movement provides an instant and sensitive response. This alignment is excellent when using charts, always pointing in harmony with the arc of the swinging pendulum.
The Stainless Steel Curb Chain is about 5 1/4 inches long with a matching bead at the end. The pendulum bob is about 2 inches long, about 9/16 inches in diameter, and weighs about 15 grams. This would be considered a light weight gemstone pendulum.
The small Stainless Steel Chamber is about 7 mm (9/32″) diameter and 5 mm high. More space is available in the chamber cap.
Remember not all gemstones are the same. Expect some slight variations, especially Fluorite.
