This is the earliest reference to diamond mining in European history. Table Cut/Old Eight Cut Ancient Hindu A History Of Diamond Cutting Early 1400s The top section(1/3), was sliced off to reveal a flat -Explain the history and development of diamond cutting. The introduction of continuous rotary motion in craft tools in the 15th century enabled cutters to grind facets into diamonds with greater ease which expanded the possibilities. This enabled Europe’s diamond supply to grow considerably. As cutting techniques matured, diamonds began to take on a new perception and demand grew but they were still rare and would continue to be until the discovery of African mines in the late 19th century. Diam… The steel wheel upon which the diamonds are cut and finished should be about the thickness of a finger & the size of an open hand and of the finest steel excellently tempered. Looking at the available literature the same thing keeps popping up: accurately translating ancient texts is very difficult. Ancient History – Middle Ages (800 BC – 1499) It is believed that diamonds were first discovered in India and kept as loose unpolished stones. The marquise diamond cut, also known as the football-shaped cut, the boat-shaped cut, the eye-shaped cut, or the navette, is rarely seen in the engagement ring world compared to other less vintage cuts.

With nearly one million employees in its diamond manufacturing sector, India is today the world's largest manufacturing centre for cut and polished diamonds, contributing 60% of the world's supply in terms of value and 85% … Descended from the step cut, emerald cuts were standardized in the 1940s. It enabled cutters to accurately shape their rough in directions which prevented cleaving from being performed.

The new religion condemned the superstitious attributes which had accompanied the stones. That this technique was probably known earlier in India can be deduced from J.B. Tavernier who wrote in 1665: …when the miners see a stone in which there is a flaw of some size, they immediately cleave it, that is to say split it, at which they are much more accomplished than we are. Perhaps this is why Europeans started to cut diamonds? But the ‘diamond’ comes from the erroneous translation of the Hebrew yahalom and Greek adamas. It is possible that the demand for perfect crystals and lack of such a supply triggered the start of diamond fashioning in Europe. This diamond is one of the very first patented diamond cuts in the world. A marquise cut diamond features 58 facets and an elliptical shape with pointed ends. This weight loss illustrates the progress in shaping diamonds. The first brilliants were anything but symmetrical and had all sorts of outlines, depending on the rough they were fashioned from. These new techniques gave rise to the old European and English round cuts, both of which have a total of 58 facets same as today’s round brilliant cuts. Plenty of customers, a steady supply of rough and mechanized cutting machines changed the ancient craft of diamond cutting into a modern industry. The most significant trait of rose cut diamonds is that they are flat at the bottom and dome shaped at the top. Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic.At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form of carbon, but diamond almost never converts to it. …It (the lead) also pulverizes the diamond… When on grinding and pulverization its (the diamond’s) pieces get smaller the jewelers coat them with something that keeps the flies away. With 58 facets, the round brilliant cut had its origin in the Mazarin technique developed all the way back in the 17th century. Main article: Mughal Cut We can’t speak about diamond cutting without getting into J.B. Tavernier’s travel accounts which have been bundled into his Six Voyages of Jean Baptiste Tavernier in which he provides a great insight into Indian diamond fashioning of the 17th century through his illustrations and text: …the mill was like ours, the large wheel of which was turned by four blacks. The new technology and enormous influx of rough from South Africa caused the glory days of the cutting houses to start. A Flemish Cutter ~1540 Using a cutting rig which he propels by kicking a wheel with his feet. Their dome shape became higher and higher as their popularity grew. The developments in the 16th century lead to a shift from a mere polishing of natural crystals to genuine ‘faceting’. In the step cut the shape of the rough diamond usually dictated the position and placement of the facets, allowing to maximize the carat weight of the final gem. Diamonds were known to and worn by the Romans. Naturalis Historia, Pliny, 1st century AD. The diamond point is simply the eight natural facets of the crystal. Finally, a new craft was added to the repertory of cutting techniques: that of diamond sawing. But asscher cut diamonds have larger step facets, a higher crown, and a smaller table.

Art books International, 1995. Diamond engagement rings gained in popularity during the Art Deco era and the round old European cut diamond was the favorite. The relative ease with which a facet can be introduced depends on its orientation to the crystallographic planes of relative hardness. Old european cuts have a round girdle, meaning they appear round from the top view as opposed to the earlier old mine cut which had a more squared off top view. This cut was the marquise cut, also known as the navette cut. It was during the 15th century that it was discovered that diamonds could be cut by their own dust! Cutters, therefore, have to introduce facets on planes which differ a few degrees from the harder crystallographic planes.
