According to EdwardJayEpstein.com:
"Until the late fifteenth century, diamond cutting had been a primitive business. Diamonds were first cleaved by placing a chisel at the stone's weakest point of molecular cohesion and striking it with a mallet."

Ancient Egyptians may not have 'cut' their diamonds in the same way that diamonds are 'cut' today. The natural occurrence of a diamond can be a pyramid shape, and even two pyramids fused together at the base. In this incarnation, a diamond is quite beautiful and eye-catching.
they cut their stones so exact that they didn't need any cement substances
First, many, many people had to cut into the rock formations, and cut huge perfect stones to pile up for the pyramids. Second, each of thousands of stones had to be moved from the rock quarry all the way to the pyramid location. It took many people to build the wood structures needed to start building the halls and rooms that would be deep inside the pyramid. If getting the stones to the pyramid took many people, then raising the stones and piling them atop each other was major. The stones were so terribly heavy that it took a bunch of manpower to raise them and position them. So it would not take many decades to finish the pyramid, many work parties were formed to haul, raise, and lay the stones. To get the pyramid finished before the Pharoah died and would be buried in the pyramid, many, many thousands of people had to work together.
From Wikipedia: "The history of diamond cuts can be traced to the late Middle Ages, before which time diamonds were enjoyed in their natural octahedral state-anhedral (poorly formed) diamonds simply were not used in jewelry. The first 'improvements' on nature's design involved a simple polishing of the octahedral crystal faces to create even and unblemished facets, or to fashion the desired octahedral shape out of an otherwise unappealing piece of rough."

Greek temples were primarily held together using a system of interlocking stones and large blocks of marble, which were precisely cut to fit tightly without the use of mortar. The construction relied on the principles of post-and-lintel architecture, where vertical columns supported horizontal beams. Additionally, metal clamps and dowels were sometimes used to secure the joints between stones. This technique allowed for both stability and aesthetic harmony in the structures.
Quarter-cut diamond may be a pattern description. Diamond stones are not usually described as 'quarter-cut'.
In medieval times, people cut their toenails using small knives or scissors.
Not necessarily.A diamond is valued according to its cut -- round in this case, carat weight, colour and clarity.Larger stones, of course, will be more valuable than smaller stones.Larger more clear stones are usually cut in an emerald cut.Fancy coloured stones are cut to highlight not only the colour but whatever other valuable attribute exists in the stone.

From a forum contributor who apparently appraises diamonds:"Single cut diamonds are round stones with a 17-facet design. Full cut stones are round stones with a standard 58 facet design. These terms are used to describe the small stones used in groups or as decorative elements on a piece. They are collectively known as melee."
Diamonds are cut in geographies where people possess the skill to plan and cut raw diamond stones, and where the tools are available in highly secure facilities. Such geographies can be found in India, Europe, the Diamond District in New York City, and elsewhere in the world.
