A style of solitaire ring setting in the gemstone is suspended above the main body of the ring with a set of prongs. This setting style was first introduced by Charles L. Tiffany in 1886. Up until this time, gemstones were set into a rung flush with the body, usualy surounded on all sides by the metal of the band except for the very top surface of the stone; The Tiffany Setting allows light to enter the gemstone from the bottom and radiate upwards giving the gem, especially diamonds, a inner 'sparkle'.
