1) The hardest natural occuring form of the 6th element of the Periodic Table (Carbon). When cut properly it can appear to be very brilliant due its refractive index. 2) A playing field, in the shape of a square, where the corners are bases. Used to play baseball and variations of baseball, like T-Ball, softball, and kickball. 3) A 2D geometric shape with 4 sides of equal length, but with differing perpendicular angles. Actually a rhombus, but commonly called a diamond when a corner instead of a side is at the bottom.
