Those who are aware of man made diamonds know that they are similar to real diamonds in many ways. For instance, they can be graded in the same manner as mined diamonds. They also can be used for various purposes. And, just like real diamonds, they can be found in a variety of colors.
Processes used to make them
Using chemicals to create man made diamonds is a complex process. However, the end product is similar to the natural diamond in size, look and feel. Some man made diamond are used as drill bits in oil and gas drilling.
There are two primary methods for creating lab diamonds. The first is the high pressure, high temperature method. This method replicates the conditions underground that produce diamonds. However, the process can lead to flaws and is more prone to failure.
The second method is the chemical vapor deposition method. The process uses smaller machines, but is more controlled. The process simulates the formation of diamonds in a gas cloud. The diamonds produced by this method are not colorless, but the crystals do have a square or cube structure.
The process can take weeks or months to produce a finished diamond. There is also the risk of exploding diamonds during the process.
Graded in the same manner as mined diamonds
Whether you are considering purchasing a diamond or other gemstone, you should be aware of the various grading methods. These are meant to help you determine the quality of the stone.
The International Gemological Institute (IGI) is the largest diamond grading laboratory in the world. In 1981, IGI expanded its services to include jewelry appraisals. In this way, IGI certified diamonds became the standard for lab grown diamonds.
The same labs that grade mined diamonds also grade lab grown diamonds. Nevertheless, the quality of these stones varies greatly.
Unlike mined diamonds, lab grown diamonds are a lot less expensive. The initial cost of buying a lab diamond is typically 30% less than a mined diamond. And, unlike mined diamonds, lab diamonds are very durable. This makes them a better investment.
One of the most important aspects of lab-grown diamonds is that they are usually accompanied by grading reports from the leading diamond grading laboratories. These reports will detail the type of process used to create the diamond, the type of material that it is composed of, and the diamond’s color specifications.
Compare them to emeralds
Compared to diamonds, emeralds are more expensive and rare. They are often considered to be a sign of love, wisdom and invigoration. They have a bluish green color, and can have a very high value.
While diamonds are harder, emeralds are relatively soft. They are considered to be the softest gemstone. The price of emeralds varies depending on their cut, carat weight, and clarity. The price of a 4-carat emerald is much higher than a 10-carat diamond. The price of an emerald will also depend on its location. For example, emeralds mined in the Colombian emerald belt are more expensive than those mined in India.
The price of emeralds can be a major factor when you are considering purchasing jewelry. If you are shopping for emeralds, it is a good idea to evaluate your budget and priorities. If your budget does not allow you to buy a quality natural emerald, you should consider buying a lab created emerald instead. Lab created emeralds are very similar to natural emeralds, but they are less expensive. They are also more durable, so you can feel confident that they will last.
Common uses for lab-created diamonds
Several different terms are used for lab-created diamonds, including synthetic, artificial, cultured and man-made diamonds. These lab-made diamonds are used in jewelry, as heat spreaders in semiconductors, and for radiation detectors. Some lab-created diamonds are color-treated.
Lab-created diamonds are manufactured using a process known as Chemical Vapor Deposition or CVD. It is a process that uses carbon and other ingredients to make diamonds. It is a more cost-effective process than HPHT (High-Pressure, High-Temperature) diamond production.
CVD lab-grown diamonds contain traces of hydrogen, which gives them a blue color. Its high thermal conductivity makes it ideal for heat sinks in high power laser diodes.
Simulant diamonds are also produced in labs. These diamonds are chemically similar to mined diamonds. The simulant diamonds are made from alternate materials such as carbon, platinum, and boron.
The process for lab-created diamonds has been refined over the years. The quality of these diamonds has become higher, and the production costs have become less expensive.
