Testing Stone
Testing Stone
It is a fact that the demand for diamonds is steadily on the increase and this has led to several unscrupulous persons selling fake diamonds to unsuspecting and less knowledgeable customers to get rich overnight. There is a proliferation of imitation diamonds and there are traders who try to pass them off as real diamonds. While the best option is to have the diamond appraised by a gemologist you trust, it may be a costly process. The best way to avoid becoming a prey to such traders in spurious diamonds is to learn some simple ways on how to tell if diamonds are fakes or not.
Fake diamonds are not durable natural diamonds, on the other hand, are the most durable stone on the planet. First ask for a certificate and verify if it from a reliable and reputed diamond grading authority like the Gemological Institute of America or an independent appraiser who is affiliated with a professional organization like the American Society of Appraisers. If a diamond is real, the jeweler or dealer will be readily willingly issue a certificate.
If the diamond is not already mounted, then you can turn it upside down and place it on a piece of newspaper. If you can read the print clearly through the stone or even see distorted black smudges, then chances are the diamond is fake. If the stone shows any sign of double refraction, it may be Please know that Moissanite (silicon carbide) is a gemstone that almost identical to a diamond that even professionals find it difficult to distinguish. If the stone shows any sign of double refraction, it may be Moissanite. Check stone for scratches. Diamonds do not easily admit of scratches. On the other hand, Moissanite stones are easily prone to scratches. Before buying a diamond, carefully check the stone for scratches and ask the jeweler for a small magnifying glass.
Another easy way is to draw a small dot with a pen on a piece of white paper. Place the unmounted diamond over the center of the dot. Look directly down on it and if your stone is not genuine diamond, you will be able to see a circular reflection in the stone. It is also good to know that an authentic diamond’s reflections usually manifest in various shades of gray. Several diamonds that create rainbow reflections are either a cheap quality diamond or a decidedly fake diamond.
Fake stones are typically set in substandard metals. While a jeweler may claim a stone’s genuineness, they may unknowingly acknowledge an inferior metal. Cheap settings usually mean a cheap diamond stone and high quality diamonds can be set only in high quality pure metals.
When you put the diamond under a UV light, many diamonds will exhibit blue fluorescence and the presence of a medium to strong blue confirms that it is real diamond. If you instead see a very slight green, yellow, or gray fluorescence under ultraviolet light, it is likely to be Moissanite. A very simple test is to put the diamond in some water. If it is real diamond, it will sink. If it is fake diamond,it will float.
If you are a regular buyer of diamonds, it is better to buy a Diamond Testing equipments that are readily available in the market and they quickly indicate if a diamond is true or fake.
