When you’re shopping for diamonds, it can be difficult to know if they’re real or not. Unless you have an expert on hand to inspect the stone, there are a few things that you can check at home before making a purchase. Here are some tricks for determining whether your new bling is real or fake:

Water test
Place a drop of water on the diamond. If it disappears, it’s glass. If it stays there and doesn’t change color or evaporate, you’re good to go! If your diamond turns yellow or brown when exposed to water, that’s a sure sign that it’s not real.
Fog test
One of the easiest ways to test whether a diamond is real is by performing a fog test. To perform this test, place a drop of water on your diamond and gently blow on it. If your diamond is real and has been treated with consideration, it should disappear into thin air within seconds. If there are any signs that your diamond is fake or not properly cut, then there will be no change in appearance after you perform this test.
When performing a fog test, make sure that you use distilled water or saliva as these substances do not contain any impurities that could affect your results in any way. Also keep in mind that it might take some time for the actual process of dissolving diamonds with heat particles rather than super-cooled ones (which require pressure).
Refractivity test
The refractivity test is one of the simplest ways to determine whether or not your diamond is real. If you have a jeweler’s loupe, holding the stone up against any source of light will give you a pretty good idea of its authenticity. A real diamond will appear as if it’s shining with its own light, creating a rainbow effect in the stone known as “fire.” Fakes tend to look more like blurs and flecks than rainbows when viewed under similar conditions.
Scratch test
If you’re a little worried that your diamond might not be all that it appears, you’ll want to check the clarity and color of the stone. To do this, use a diamond testing kit or even just a loupe and some common sense.
For starters, pick up one of these handy tools for de termining whether your rock is real: A loupe will allow you to see the diamond up close with magnification; a microscope can help you identify any flaws in its construction; and if all else fails, there’s always good old-fashioned human sight.
Hold the stone under direct light with its table facing upward (this is where “table” comes from). Then hold it against a white piece of paper so that light shines through it at an angle onto your viewing surface. If there are markings on either side of the stone—for example, if there are two rows separated by tiny indentations—check those out as well by looking through both sides while holding them against paper again.* Check out what looks like tiny specks inside each facet: If they appear evenly distributed throughout rather than clustered in one area or another, then they could be natural crystals formed during growth processes which would indicate authenticity!
A jeweler can tell you if a diamond is real, but there are also at-home tests you can perform to find out for yourself.
The water test involves filling a glass with water and dropping your stone into the glass. If it sinks, it’s not real; if it floats, it is. The fog test involves using a laser pointer to “fog up” the stone (turning its surface opaque), then trying to shine light through the foggy area of your diamond with an ultraviolet light source such as a UV flashlight or penlight. If you can see light coming through, then this means that your diamond has been cut with clarity in mind and therefore isn’t natural (in other words: fake).
The refractivity test uses magnification so that you can examine your stone more closely using either magnifying glasses or microscopes—the latter being preferable since they allow for greater magnification capabilities than those offered by standard eyeglasses alone—and determine whether there are imperfections within its structure that would indicate something was wrong about how said thing was made. This method allows both non-experts like myself as well as experts like my favorite professor at UCLA’s School of Theater Film & Television who taught me how important authenticity matters when making movies based on true stories by asking questions like: “Is this really an authentic representation?” which forced us all
