How To Know If A Diamond Is Real by Nobody: 9:50pm On Sep 02, 2014 |
How to Tell if a Diamond is Real Finding out whether or not your diamond is real is a tantalizing proposition — do you want to know without a doubt? Most curious citizens turn to a professional jeweler in order to suss it out. But you don't have to be Sherlock to tell the real from the duds. A little bit of light, some water or warm breath, and a jeweler's loupe is all you need. See Step 1 for additional details and information about the wonderful world of diamonds. Method One of Five: Testing Mounted Diamonds at Home 1 Use the fog test. Put the stone in front of your mouth and fog it like you would a mirror. If it stays fogged for a couple seconds, it’s probably a fake — a real diamond disperses the heat from your breath instantaneously and won't fog up easily. Even if you wait in between fogging it up and looking at it, it will still clear much faster than a fake. It can help to use a stone you know is real next to the suspect stone and fog both. You can watch how the real one stays clear while the fake one fogs over; if you breathe on fake diamonds repeatedly, you will see condensation start to build up. With each puff, the fake stone will fog up more and more, while the real one will still be clean and clear. 2 Check the setting and mount. A real diamond is not likely to be set in a cheap metal. [1] Stamps inside the setting indicating real gold or platinum (10K, 14K, 18K, 585, 750, 900, 950, PT, Plat) are a good sign, while a "C.Z." stamp will give away that the center stone is not a real diamond. [2] C.Z. stands for Cubic Zirconia, which is a kind of synthetic diamond. 3 Use a jeweler's loupe to inspect the diamond. You can usually borrow one from the jewelry store. Mined diamonds usually have small naturally occurring imperfections, which are called "inclusions," that can be seen with a loupe. Look for small flecks of minerals, or very slight color changes. These are both signs that you're dealing with a real, albeit imperfect, diamond. Cubic zirconium and lab-grown diamonds (which should pass all of the other tests) usually don't have imperfections. That's because they are grown in sterile environments instead of produced by chance in the Earth's laboratory. A gem that is too perfect is more often than not a fake. Is it possible, however, that a real diamond will be flawless. Don't use imperfections as the determining factor in whether your diamond is real or not. Rule out fakes using other tests first Method Two of Five: Testing Unmounted Diamonds at Home 1 Look at the stone's refractivity. Diamonds sharply bend, or refract, the light that passes through them, resulting in their strikingly brilliant appearance. Stones like glass and quartz sparkle less because they have a lower refractive index. A stone's brilliance is difficult to alter in any way, even with an expert cut, because it's an inherent property of the stone. By taking a close look at the stone's refractivity, you should be able to tell whether it's the real thing or a fake. Here are a few ways to do it: The newspaper method: Turn the stone upside down and place it on a piece of newspaper. If you can read print through the stone, or even see distorted black smudges, then it probably isn't a diamond. A diamond would bend the light so sharply that you wouldn't be able to see the print. (There are a few exceptions: if its cut is disproportionate, the print can still be visible through a real diamond.) The dot test: Draw a small dot with a pen on a piece of white paper and place the stone over the center of the dot. Look directly down on it. If your stone is not a diamond, you will see a circular reflection in the stone. You won't be able to see the dot through a real diamond. 2 Observe the reflections. A real diamond's reflections usually show up in various shades of gray. Look straight down through the top of the diamond. If you see rainbow reflections, you're either dealing with a low-quality diamond or a fake Instead, check for "sparkles." A real diamond will sparkle significantly more than an equivalently- size piece of glass or quartz. You may want to take along a piece of glass or quartz as reference. Don't confuse sparkle with reflection. Sparkle has to do with the brilliance or intensity of the light that's refracted by the cut of the gem. Reflection has to do with the color of the light that's refracted. So look for intense light, not colored light. There is a stone that has even more luster than a diamond: moissanite. This gemstone is so similar to diamond that even jewelers have a hard time telling them apart. To tell the difference without special equipment, hold the stone close to your eye. Shine a penlight through the stone. If you see rainbow colors, that's a sign of double refraction. This is a property of moissanite, but not of diamond. 3 Drop the stone in a glass of water and see if it sinks to the bottom. Due to its high density, a real diamond will sink. A fake one will float at the top of the surface or in the middle of the glass. 4 Heat up the stone and see if it shatters. Heat up a suspect stone with a lighter for 30 seconds, then drop it straight into a glass of cold water. The rapid expansion and contraction will overwhelm the tensile strength of weaker materials like glass or quartz, causing the stone to shatter from the inside. Real diamond is strong enough that nothing will happen. . source. http://www.naijaxplorer.com/forum2_theme_111605920.xhtml?tema=2 |
