Crystalized carbon. Diamond is a cubic mineral, like gold, spinel, fluorite, etc. Its ideal crystal shape is eight-sided -- two pyramids attached to each other. Its refractive index is 2.42, as opposed to cubic zirconia which is 2.15; sapphire and ruby which are 1.77; emerald, aquamarine, heliodore and morganite which are 1.57, and so on.
Diamond is rated as a 10 on the Mohs hardness scale, but only because it is the only natural gem harder than corundum (sapphire and ruby) which are a 9 on the scale. In reality, diamond is more like a 41 -- its not just a little harder than corundum, but mucher harder.
Diamonds are mined in South Africa, Australia, Siberia, Canada, Brazil and a few other lesser places. Most gem-quality diamonds mined are a light yellow or light brown color, but the stones occur naturally in every color of the rainbow, including colorless (which is the most popular for jewelry), milky translucent white and opaque black.

n. Relatively common mineral, consisting of carbon, which is similar in appearance to zircon or cut glass. Used by the South African based De Beers company as a form of emotional blackmail through clever, original, and socially planted marketing techniques. It is asserted by the De Beers company that a man who is unwilling to waste a huge amount of money for a worthless piece of carbon must not really love his future wife very much.

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.

A guy who can't get a girl because all of them decide to claim him as a best friend. Every chick claims he's attractive, but every chick says there is someone out there for him. Probably not though.
