Look for Flaws Under a Magnifying Glass <\/span><\/h2>\nOne way to spot a fake diamond at home is to look at it under a magnifying glass. Get a magnifying glass (of ten times magnification or higher) and compare your suspected fake to a diamond you know is real. In this test, finding flaws (internal and external) is actually a good sign that your diamond is likely to be real. <\/span><\/p>\nReal diamonds are formed over many years in the earth\u2019s crust. This natural formation leads to some flaws on the diamond, flaws that will look like tiny scratches under magnification. Many fakes, on the other hand, have no flaws at all, as they were made in a lab. <\/span><\/p>\nOne thing to note about this, however, is that some real diamonds may have no flaws if they are internally and externally flawless. This type of natural diamond is incredibly rare (and tends to be incredibly expensive) but it is possible that your diamond may be flawless rather than fake. If you\u2019re unsure after doing the magnification test, you can always take your diamond into a jeweler for a second opinion. <\/span><\/p>\nTest the Density of a Fake Diamond<\/h2>\n
Here\u2019s a simple way to spot a fake diamond: place the loose stone in a glass of water and watch how it sinks. Real diamonds are very dense and will sink to the bottom of the glass. Many fakes will not and will either fall slowly or float. This test works best on smaller stones, as larger fakes may have enough weight to sink quickly, even though they may not be as dense as a real diamond. <\/span><\/p>\n
