No one knows exactly when, where or who made the first attempt to cut diamonds. It is assumed that the first diamond cutting styles originated from India. However, it was only limited to chipping or grinding. In ancient times diamonds were valued more for their magical and mythological properties. It was thought that by modifying the natural state of a diamond in any way would alter its magical properties and render it useless. At the most the cleaving techniques of diamond were attempted to get flat faces on diamonds. It is believed that the early diamond cutting styles originated in Europe. The European travelers visiting India for its diamond treasures used to transport diamonds from the Golconda Mine to Europe for cutting.
Experimentation with diamond cutting did not yield any significant results till the seventeenth century. The early diamond cutters were unable to polish the rough octahedral diamonds. However, they found out that they could polish or grind diamonds into a point by polishing almost parallel to the diamonds rough faces, at an angle lesser than the diamond rough faces. They also realized that only diamonds cut diamonds. Hence they used a wooden table covered with diamond dust to achieve any kind of polishing. This resulted in the "Rose Cut". It was called the rose cut due to its resemblance to the "Rose Bud". The rose cut came into existence in the early sixteenth century and was widely used till the early nineteenth century.
However, whilst you cannot scratch a diamond with a piece of steel, if you hit a diamond with a large bit of it (called a hammer) the diamond can easily be chipped, split or even shattered!
The cutter makes a paste out of crushed diamonds and puts it on the blade he/she is going to cut the diamond with. Since only diamond can cut diamond, this is a useful and clever trick.
Using the query 'diameter' assumes that the diamond is a round brilliant cut. A 2.50 carat round brilliant cut measures about 9MM at the girdle -- your diamond's diameter will be slightly shorter.
Raw diamonds are probably sorted first as to colour and clarity, those being the highest-value natural characteristics. When cut and polished, the goal is to preserve as much of the stone's clarity as possible while holding up its carat weight. Often the cut of a diamond is determined by these factors. For example, this means that larger fancy coloured or 'white' diamonds can be cut in the emerald style, because of the cut's ability to show off flawless or internally flawless clarity and desirable colour.
There is no direct correlation between a diamond's cut -- i.e., its linear measurements to carat weight. There can only be approximations. For example, a shallow cut will measure larger than a deeper cut stone.
Diamond value depends on the '4 Cs': cut, color, clarity and carat weight.
No. Only another diamond can cut a diamond.
No. Only diamond can cut diamond.
A radiant cut diamond is a diamond cut invented in 1977 by Henry Grossbard that infuses the rectangualar or square shape of an emerald cut diamond with the brilliance of a round diamond.
Diamond Cut was created in 1978.
Given the proper environment, a diamond can cut anything, including another diamond.
No. Diamond is the hardest mineral known. It can only be cut by another diamond.

Quarter-cut diamond may be a pattern description. Diamond stones are not usually described as 'quarter-cut'.
A diamond will cut glass -- an emerald will not.
