What is Diamond Dust Used for?

C. Palmer
C. Palmer

Diamond dust is essentially the leftover material from cutting diamonds. It is extremely hard and has a wide variety of uses. Items made with this dust are considered to be of high quality and are used in a variety of things in various industries from construction to the beauty industry.

One such use is for the blade of a saw. Diamond blade saws, used in construction, can be circular, blade or frame set. The diamond dust inset in the edges of these saws make them incredibly sharp and able to cut through hard surfaces such as granite, marble and tile. This dust is also used for industrial drills, grinders and files.

Diamond dust is also used both as an industrial polish and a preventative. As a high-quality abrasive, it can be used to polish other surfaces to a nice shine. On the other hand, it is also used in industrial abrasion-resistant coatings.

It is no surprise that the only thing that can cut a diamond is another diamond. As a result, saws used to cut other diamonds, called scaifs, have diamond dust on their cutting surfaces.


Another use is in the beauty market. Nail files that are made with it are considered to be premium files that stay sharp and last for a long time. They are generally made of steel and then coated with diamond dust particles. The dust is also added to some brands of nail polish and nail treatments to resist chipping of the enamel and to strengthen the nail.

Diamond dust has also gone high-tech. Makers of flat screen televisions are incorporating it in the TV's nanotechnology. Researchers have found that these microscopic diamond particles emit electrons at a lower voltage than any other known substance, which makes it possible to change the size and shape of the average television.

Still another use is the more obvious area of jewelry. Necklaces and earrings that feature industrial diamond dust encased behind quartz crystals is just one way the dust can be used.

@ahain - Diamond dust usage in flatscreen tvs is a pretty new technology -- 2000 to 2009, when LCD won out as the big technology of choice, roughly. If your tv was made during those years and it's a flatscreen, it might just have diamond dust inside!


Wow, diamond dust is in flatscreen tvs? I wonder how new a tv has to be to include diamond dust as an ingredient; mine is a flatscreen, I think, but it's not a brand new one or anything.

Since diamond dust particles used in the nanotechnology of flatscreen tvs emits lower voltage electrons than other stuff they used to make tvs with, does this mean that tvs with diamond dust consume less power? That would be really cool for the environment, especially since diamond dust is an all natural substance.


@SkyWhisperer - Diamond dust tools are the best! I do woodworking as a hobby, and I find that blades with diamond dust coatings make superior clean cuts with my scroll saw. Did you know that diamond dust is also used in some sandpaper? It follows the same rules as making a nail file out of diamond dust, I'd imagine, except that instead of steel, the sandpaper is of course a paper backing for the grit.


Diamond dust is very strong material and can cut through a lot of surfaces. For this reason you find it in diamond tools. I have a diamond dust hole saw, for example, that I use to make holes in glass sheets I use for some of my construction projects.

The bits get hot however so you have to pour cool fluid on them, but otherwise they work great. You can also use them on ceramic tiles or other fragile surfaces for which you need a strong bit that will not break the material.


My kids watched the Japanese anime film called the Diamond Dust Rebellion. Its basic plot is about a main character who is given the responsibility of guarding a sacred artifact called the Ouin. Well, it gets stolen and of course the main character gets accused of being the thief when in fact some other guy stole it. False accusations fly, and there is a showdown at the end.

My kids watched it twice and I followed along asking questions from time to time but not really getting everything. We don’t watch a lot of anime but I thought that it was good overall.


Any information on so-called "diamond dust" mirrors, popular in the late 1800s and early 1900s?


I want to know the process for setting / embedding / impregnating diamond dust in jewelry making.-- G.J.Patel


Can you tell me where I can find diamond dust or glitter for sprayed textured ceilings?


Where can one buy diamond dust? How much does it cost?
