In geometry, a rhombus (or rhomb; plural rhombi) is a quadrilateral in which all of the sides are of equal length, i.e., it is an equilateral quadrangle. If any angle of an equilateral quadrangle is a right angle, then all its angles are right angles and it is also a square. ...

A diamond is the hardest known natural substance. It is crystallized carbon. Diamonds are mined in their rough form and then, cut and polished to reveal their brilliance.
Diamonds, a form of crystalline carbon, are prized because they are exceptionally hard and durable, have high refractivity and brilliance, and because really fine diamonds are rare. Today diamonds are valued based on the "4 C's" of color, cut, clarity and carat size. ...

Extremely hard, highly refractive colorless or white crystalline of carbon. Diamonds, like all gemstones, are judged in terms of Carats, or weight (different from Karats, as in gold purity).
