All You Need To Know On Raw Diamonds
Learning all you need to know on raw diamonds will help you to recognize them when you find them in their natural forms or when you are purchasing them from others. Diamonds look very different when they have been cleaned and polished compared to when they have just been found and you might not be able to properly determine whether you are holding a raw diamond if you don’t understand what they look like and the tests that should be administered to them.
Locating Diamonds in Nature
Learning all you need to know on raw diamonds will help you to determine where they are found and the locations of these minerals might just surprise you. There are two main ways a diamond can be located and they are:
- Pipe Diamonds
- Placer Diamonds
Pipe diamonds are found in the earth, in volcanic pipes where coal is heated and put under such pressure that diamonds form. This is always the starting point of a diamond but they can also be moved due to erosion and this means that they can also be found in rivers that lead from these volcanic pathways. When the diamonds are located in rivers and streams, they are called Placer diamonds.
The Thermal Conductivity of Diamonds
On your quest to learning all you need to know on raw diamonds, you will come across the topic the thermal conductivity many times. This is because diamonds are extremely effective heat conductors and this is one of the best ways to determine whether you are holding a diamond in your hand or not. When testing this type of conductivity, miners will usually heat the stone and test how quickly it disperses this heat onto other objects. The more effective it is at doing this, the better a conductor of heat it is.
The Raw Diamond Scratch Test
The diamond scratch test should be included in all you need to know on raw diamonds because it is one of the most effective ways of determining whether a precious stone is a diamond or not. In days gone by, people used to assume that diamonds were so hard that they could be beaten with a hammer and not break; those that did failed the test. The problem with this is the fact that diamonds, while being one of the hardest materials on earth, also happens to be very brittle and so they tend to break under such strain.
Instead of hitting the stone, you should attempt to scratch it to determine whether it is a diamond or not. This type of test is done using a mineral of known hardness and scratching it against the material you are looking to test. Diamonds have a hardness of 10 and this means, if you are scratching it with a mineral of a hardness level lower than that, it should not show damage or it is not a diamond.
