Whether you are interested in learning how to buy a diamond or how to buy a diamond ring, you will do well if you read this article. When buying a diamond or selling one, there are four key things to keep in mind, namely the diamond Cut, Clarity, Color and Carat. Of course, some people say that there is the 5th C which is the diamond Cost of course. The cost of the diamond is dependent on the 4 C’s.
Using a 鑽石淨度 tester and a jeweler’s loop can also help in detecting fake diamonds by checking the refraction of the light and any scratches on the diamond, respectively. Try to subject diamond to as many tests as possible. If the results are rather vague, secure the diamond’s certification. The most reliable certifications are issued by the European Gemological Laboratory or the Gemological Institute of America. Certified diamonds are more expensive because the certification process generally costs at least $100. Yet, this certification helps create peace of mind.
The cut is a measure of the reflective qualities and the overall brilliance of the diamond. The better the cut, the more brilliant a diamond is going to be. The perfect cut is one that reflects the most amount of light back at you when you stare into it. The key to achieving a good cut in a diamond is the angles that are used in the process. If the cuts on the underside of the diamond are to flat, then light will not be reflected back through the diamond. Instead, the light will simply pass right through it. In order to give off the most brilliance, the cuts must be proportional in order to allow for the right reflection angles. This is something that you will often hear big name jewelers such as Kay Jewelers discussing when they are advertising their diamond price.
Regarding the recommended color range of the Marquise diamond, one has a bit more flexibility with the Marquise. As always, it is difficult to give an objective guide to the preferred color level of a diamond, as it is a very subjective rating. Some people like the colorless or near colorless look more, and others prefer the “warmer” look of a tiny tinge of color in the stone. The generally accepted preferred range though for Marquise is that the best colors are up to the G-H range, with many actually preferring the side of the warmer G and H colors levels more so than the cooler and more “icey” level of more colorless levels.
The grading procedures will still remain the same as the normal diamonds when it comes to heat treated diamonds. If the stone in question has a deep colour to it, then the grade will be according to that colour. However, the original colour will be stated in the documentation and a remark that it has been treated will be noted.
I’ll be explaining everything you need to know about how diamonds are priced, and specifically how the clarity can effect the overall value of a stone.
In my opinion, the culet is not really anything to be afraid of, and as long as it is proportional and symmetrical with the diamond it should not affect the diamond negatively in any way.
