The culet is simply a facet at the bottom of the diamond. Sometimes the culet is polished as a flat facet, also known as the culet being left open, and at other times, fairly common today, is polishing the culet to a point, also known as closing the culet.
Using a diamond 4c 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 $100. Yet, this certification helps create peace of mind.
Many diamond price are over graded by one color grade and one clarity grade, to make them easier to sell. This may sound minor, but 1 carat diamond can easily lose its value in 1000$ or more due to a false grading! A certificate from a respected laboratory will give you an accurate assessment and will help will avoid this problem.
Color: the moment you think about diamond, first thing which strikes your mind is a sparkling white stone, generally diamonds are found in white or colorless. There are colored diamonds also which are priced little less than the colorless ones. The colored diamonds are often not preferred as white diamonds do. So make sure you get a pure white stone which sparkles well if you’re opting for a colorless one.
A stone with a diamond color grade of D is absolutely colorless. This will sell for about twice the price of an N grade diamond, all other factors being equal. The jeweler and diamond experts who understand diamond color will have a lot to say about the difference in color between these two stones. But the truth is that the average buyer couldn’t pick them apart, even in ideal conditions, let alone once they’re mounted and being worn. Once you understand this fact, you’re in a much better position when you buy a diamond. So there’s no need to worry about the diamond color grade or the grades for any of the other criteria. The one test you need to apply is “Do I like it?” Then you can go as far down in price as you like, as long as you can keep answering “Yes” to that question.
Clarity is the next factor you will want to consider. You will want your diamond to be as perfect as possible. A perfect diamond refers to a diamond that is absent of any flaws. It is very rare to find a diamond with no flaws at all. The key is to get a diamond that has the least amount of flaws as possible. Any flaws that there are should not be seen by the naked eye. Sure signs of a bad diamond are: tiny spots of black or white and Cracks, which have the potential to cause the stone to split. It is important to have the clarity determined by a reliable source.
As with anything else, the simplest thing you can do to protect yourself when shopping for a men’s diamond ring is to shop informed. Knowing what to look for is the first step to avoid being scammed.
