    Start with a Diamond
    Start with Setting

    4506348467_e87ee73c82Diamonds are supposed to be a girl’s best friend. But you can rest assured about its authenticity only after you have conducted a few tests to that effect.  Most cubic zirconias of good quality are amazingly similar in shape, size and color, and sometimes even a good jeweler finds it difficult to tell the difference. This of course does not mean that you should take someone else’s word for it. Conduct the most common tests and find out for yourself.

    The Scratch Test for testing diamonds is the oldest and most traditional. However, this test though being used often is not as accurate or reliable as once imagined. Everybody knows that a true diamond will scratch glass while an imitation cannot and therefore takes it to be a good sign of its authenticity. However, as modern technology has proved of late, there is high quality cubic zirconia that can also scratch glass. Hence this method falls short. The reason why many hesitate to use the Scratch Test is that in case the diamond is real, subjecting it to the test may cause damage and lower its value.

    The Transparency Test requires you to place the stone being tested on a newspaper. If you are able to read the print clearly, it proves that the stone is a fake as cubic zirconias are transparent. Diamonds on the other hand do not allow you to read the print clearly as they are not transparent. The test however has its own limitations. The diamond should be loose and not set in a piece of jewelry, and in case the real diamond has a cut that is too shallow it will allow you to read the print more clearly. Once again, the results are therefore not really reliable or accurate.

    For the Fog Test you have to hold the stone in your hand and breathe over it to fog it. If the stone gets instantly clear and the heat is dispersed instantaneously, it means that the stone is a genuine diamond (diamonds do not hold heat),  but if the stone remains foggy it proves that the stone is a cubic zirconia. It is essential to ascertain that the stone is first cleaned thoroughly of all dirt and oil before conducting this test.
    If you have a carat or gram scale, you can conduct the Weight Test. To ascertain whether the diamond is real or not, purchase a similar cubic zirconia that has the same size, color, dimensions and shape. Place the stones side by side on the scale. The cubic zirconia is almost 50% heavier than the real diamond.
    One of the easiest and simplest tests to conduct is the Dot Test. Diamonds reflect light through its top surface or the “table” whereas cubic zirconias being transparent reflect light in a very different manner. Draw a small dot on a white piece of paper and place the stone on the dot, face down. If it is genuine, you will only see a much distorted version of the dot as the diamond is not clear. The cubic zirconia will show a clear dot.

    When placed under UV light or black light, diamonds show a blue fluorescence. 99% of imitation stones and cubic zirconia do not show fluorescent blue. However, if the diamond shows about 20% of blue fluorescence it means that it is not very valuable.

    Look through a magnifying lens and conduct the Loop Test to find out the truth of your diamond. Characteristics like girdle appearance and facet joints will tell the story. A faceted and frosty girdle means that the stone is a real diamond whereas a waxy and slick girdle shows that it is a fake. In the same way rolled facet joints show that it is a fake while very sharp joints tell you that it is genuine. Other flaws like carbon, pinpoints, cracks etc will tell you that it is a genuine diamond because it is not possible to place these flaws in a fake gemstone.

    Finally, to find out if your jewelry is really cubic zirconium jewelry, it pays to focus on the type of “stamp” inside the jewelry setting. If the stamp indicates that the stone is set in platinum or real gold it will have the words 10K, 18K, 585, 900, Plat etc written which tells you that the chances of the stone being real are good. Also look for the letters CZ which tells you that the stone in the center is cubic zirconia and not a diamond.
