Diamonds are ordinary at first glance. We’re not talking about the brilliant shiny gem-quality diamonds that are sold in stores, but the diamonds that are still embedded in igneous rocks known as kimberlites and lamproites. The uncut diamond does not show its prized optical properties. The true beauty of the transparent lustrous diamond is realized through cutting/sawing, bruting and polishing process.
Concrete is ordinary at first glance. It’s plain, gray and dull. Although it dates back to the Roman Empire, such as the infamous Colosseum building that was largely built of concrete, concrete’s true beauty was not realized until several decades ago when concrete polishing was born.
The true beauty of a diamond must first go through the diamond cutting process. This involves sawing the diamond rough into separate pieces. Grinding or bruting them into a round shape. And at last, the final facets are cut and the final polishing is performed.
The true beauty of concrete must first go through the concrete polishing process. You must first remove the existing coatings. Seal the cracks and joints with an epoxy. Grind in several stages using different metal bonded diamond grits. Apply a chemical hardener. And the final steps involve many stages of polishing the concrete floor.
Ironically, as iron sharpens iron, a diamond now sharpens concrete. Since diamonds are the hardest known mineral, it’s the perfect abrasive tool to remove existing coatings. Grinding the concrete polish requires a metal bonded diamond grit. A polished concrete floor also requires a resin bonded diamond to achieve the luminous polished concrete.
The polished concrete process was born just several decades ago. Although the entire process was accidentally discovered, the beauty of the dull gray concrete was at last realized. The polished concrete floors permeate vibrant colors. It shines luminously. It’s smooth to touch. It adds character to the architecture. It’s economical and long lasting. It’s low maintenance. It’s aesthetically pleasing and elegant.
After the diamond cutting process and the concrete polishing process, you’re left with a hidden gem underneath the surface. It gleams with luster and vibrancy. They’re both long lasting, rock hard, and beautiful. Both are truly a diamond in a rough.
