High-quality diamonds are an input used in the production of diamond rings. If the supply of high quality diamonds increases, it implies that the production of diamond rings would increase. As a result of the increased production, the supply curve would shift to the right. This would lead to an excess of supply over demand known as a surplus. This would cause equilibrium price to fall and quantity to rise.
