Diamonds are cut with specialized tools that make use of diamond tipped phosphor bronze or diamond dusted steel blades. Such tools are used to exploit the structural weakness of the diamond by grooving and striking along specific tetrahedral planes.
What is the best cut for a diamond?
The most popular diamond shape, the round cut was invented through jewelers’ attempts to create a cut with the most facets and shine. Today, more than 75% of the world’s diamonds are cut in the brilliant style. Its 58-facet cut is calibrated according to a precise formula to achieve maximum sparkle.
How can steel cut diamonds?
Diamond cutting is done by cleaning or sawing the diamond with a steel blade or a laser like the Sarine Quazer 3. The rough diamond is usually placed in a wax or cement mold to hold it in place and then cleaved along its tetrahedral plane, its weakest point. If no point of weakness exists, instead sawing is used.
Do diamonds cut metal?
Yes, certain diamond blades can cut through metal, but this will depend entirely on the blades application. Most diamond blades are used to cut through concrete, brick, tile, and asphalt. … Usually, each blade is specialized to cut a certain material or hardness of materials.

Which diamond cut is most expensive?
The most expensive diamond cut is the round brilliant
And it’s not just because it’s the most in-demand: The round brilliant has the most facets of any shape, which require more precision work, and cutters have to discard more of the rough diamond, so you essentially pay for a larger stone than you end up with.
Is steel harder than diamond?
Are Diamonds Stronger than Steel? … However, a diamond is not stronger than steel. Steel is also denser than diamonds because each molecule weighs much more than a carbon atom alone. A diamond’s smoothness allows it to easier to resist wear and tear for tools such as diamond tipped drills.
What’s harder than diamond?
Moissanite, a naturally occurring silicon-carbide, is almost as hard as diamond. It is a rare mineral, discovered by the French chemist Henri Moissan in 1893 while examining rock samples from a meteor crater located in Canyon Diablo, Arizona. Hexagonal boron-nitride is 18% harder than diamond.
Are Diamonds bulletproof?
It doesn’t seem unreasonable to wonder whether diamonds are bulletproof, since diamond is the world’s hardest natural material. Diamonds are not however bulletproof in general, as while they are hard, they are not particularly tough and their brittleness will cause them to shatter when struck by a bullet.
Why is diamond so expensive?
A diamond is the hardest material on the earth and the most expensive gemstone as well. Diamonds are not rare but high-quality diamonds that can be used in the jewelry are rare. … In addition, the size and quality of the diamond also plays a major role on the price. These are the reasons why diamonds are so expensive.
Can Diamond only cut diamond?
The hardness of the diamond prevents arbitrary cleaving; instead, the shape of a diamond cut is related to the natural shape of the rough stone. … Using these imperfect stones as cutting grit belies the main theory: only a diamond can truly cut another diamond.
Can you melt a diamond?
In the absence of oxygen, diamonds can be heated to much higher temperatures. … The ultimate melting point of diamond is about 4,027° Celsius (7,280° Fahrenheit).

How GIA assigns a diamond cut grade. GIA evaluates a round brilliant diamond’s cut based on seven components – brightness, fire, scintillation, weight ratio, durability, polish and symmetry – to arrive at a GIA diamond cut grade, which ranges from Excellent to Poor.
Is a diamond worth more cut or uncut?
Bottom Line. The natural quality of a rough diamond (carat, color, and clarity) determines the value of a cut and polished diamond. The cutting process is very exhaustive and requires immense skill, so raw, uncut diamonds will almost always be less expensive than a cut diamond with the same carat, color, and clarity.
