rubies
A synthetic material made from carborundum is used to reduce the friction and reduce wear at key points in the movement such as the pallets, the impulse pin and the balance staff. They are also used to counteract end play in the balance staff and gear wheels. Only diamonds have greater hardness than rubies. Traditionally, natural rubies were used but these have now been replaced by synthetic stones.
