The Gaston rebound tester is used to determine the relative elasticities of various minerals. Under this test fluorite, pyrite, quartz, and garnet are shown to be more elastic than steel. The remarkable rebound of 97 per cent was obtained on garnet, the elasticity of the ball itself being only 92 per cent on this scale.
