What is Hardness?
Diamonds are the hardest material on Earth. Diamond is the hardest substance known to man. Diamond is 100 times harder than any other material on Earth, including corundum (a crystal found in coal and other sedimentary rock). Diamond is so hard that it can only be scratched by other diamonds.
So how do you test to see if a diamond is actually scratch-resistant? The only way to know for sure is to scratch the diamond with a sharp object. If the diamond scratches easily, it’s not a true diamond.
True diamond can only be scratch by other diamond.
How to Test Diamonds (Scratch Method)
Diamond are grad on a scale of 1 to 10 with the higher number indicate a finer diamond. However, the only hardness test that will identify a diamond is scratch corundum. This test is simple and can be done at home. All you need is a polished corundum stone and your fingernail. The goal is to scratch the stone without causing any damage. If you can do this without breaking the stone, then the diamond is scratch and is consider to be of lesser quality.
Other Tests to Determine the Quality of a Diamond
There are many tests which can be use to determine the quality of a diamond. The only hardness test that will identify a diamond is scratch corundum. Diamond with a hardness of 6 on the Mohs scale are the hardest and are consider to be the highest quality diamond.
What Are the Difference Between Rubie, Sapphire and Emerald
When it come to diamond, the three most popular gemstone are Rubie, sapphire and emerald. But what make these stones so different? Here’s a look at the main difference:
Ruby:
Rubies are the most common type of diamond, and they’re known for their intense red colors. The color is due to the chemical element rubies contain, called corundum.
Sapphire:
Sapphires are usually lighter in color than rubies, and their hue can vary from blue to violet. They’re also one of the most durable types of gems, which is because sapphires don’t contain any colorless or light-colored stones. In fact, sapphires have the highest refractive index of all gemstones (meaning they have the highest ability to transmit light).
Emerald:
Emeralds are some of the most rare types of diamonds, and their colors can be deep green or blue green. They also have the highest refractive index of all gems (meaning they see things clearly), making them one of the most valuable.
Conclusion
I hope that this article has helped to clear up some of the myths about diamonds and answer some questions you may have had. As long as you are aware of the three key factor when it come to diamond hardness, then any test can be use to identify a diamond. In addition, by know how much pressure is need to scratch corundum, you can also determine the hardness of other gemstone. So whether you’re look for an affordable way to assess diamond hardness or just want to know more about what makes a diamond unique, I hope that this article has been helpful.
