We must, however, identify your stone before any work starts. Please just get in touch for a quote to set your stone into one of our many settings. Some misguided articles suggest heating a diamond, then dropping it into cold water. Theoretically, this could prove that your diamond is real.
To explain, some synthetic gemstones may shatter as a result. However, should your diamond have internal flaws and surface breaks, a real diamond could fracture in a similar way. Extremes of temperature can affect a real diamond. When a diamond glows under UV light, this does not mean you have an artificial or fake diamond. Some diamonds reflect UV light in varying degrees. As a result, some diamonds appear to glow under intense UV light.

Some cost far less than diamonds. But many lack the hardness and dazzle of a diamond. Here are just some gemstones used as diamond substitutes. White Topaz costs far less than other gemstones. Also, White Topaz occurs in various fancy shapes.
Some buyers use White Topaz instead of a diamond. Real diamond shoulders work well alongside Topaz. Perhaps the best fake diamond substitute. Both Sapphires and diamond make tough gemstones, well suited to rings worn every day.
Moissanite was discovered in by the Nobel Prize-winning chemist Henri Moissan. He found the natural form of this gemstone within a meteorite in Arizona. At first, mistaken for diamonds, he later established the crystals were formed from Silicon Carbide.
Owing to the rarity of natural Moissanite, almost all Moissanite is lab-grown. Furthermore, this diamond alternative appears similar to diamond, with visual differences. For example, the brilliance of both types of gemstone differ. Compared to a diamond, Moissanite features double refraction. To the trained eye, Moissanite sparkles with additional brilliance compared to a diamond. Moissanites provide one of the least expensive, durable alternatives to diamond.
Furthermore, their low cost makes them an attractive option for engagement ring buyers. Learn more about our Moissanite engagement rings available at Serendipity Diamonds. Lab-grown diamonds look identical to real diamonds , with the same physical appearance and properties. For this reason, most feature an inscription on the girdle of the stone. Lab-grown diamonds work out less expensive than natural.
We provide lab-grown alternatives to our rings upon request. Please contact us for a quote on our lab-grown options to any of our engagement rings. Mark attended Liverpool University and went on to pursue a career in the diamond industry. After more than a decade working in polished diamonds, Mark moved to the Isle of Wight where he launched Serendipity Diamonds. He works most days from their busy Ryde showroom, photographing jewellery and writing for the Serendipity Diamonds website.
Serendipity Diamonds Ltd. England No. PO33 2PN. Use this simple test to ensure a diamond is real. Carefully drop the loose stone into the glass. If it floats underneath or at the surface of the water, you have a fake on your hands. A real diamond has high density, so the water test shows if your stone matches this level of density.
For the fog test, hold the diamond or ring between two fingers and breath on it with a puff of air. A light fog will form on the diamond because of the moisture and heat in your breath. If the fog dissipates right away, the diamond is real. If it takes several seconds for the fog to disperse, it is likely a fake diamond. For example, a real diamond will be set in materials such as white gold, platinum, yellow gold, pave or side-stone setting and halo setting rings.
As an example, the notes 10K, 14K, and 18K indicate the type of gold used. The markings PT and Plat refer to platinum. If you see a number such as , , , and , those are markings indicate platinum or gold as well.
To test this, grab a drinking glass and fill it with cold water. Use a set of plyers or fireproof gloves to hold the stone. Heat the stone with a lighter for approximately 40 seconds, then drop the stone directly into the cold water. If the stone shatters, it is made of weaker components and is not a real diamond. A true diamond will show no reaction.
This method tests the quality and strength of the stone. Because of the quick expansion and contraction of heat, weak materials like glass or cubic zirconium will crack and break.
Think of a glass or Pyrex dish you use for cooking. If you pull the dish out of a hot oven and try to wash it immediately, the shock in temperature change may shatter the dish. Because diamonds are one of the strongest materials on the planet, it will be resistant to such heat tests. To test a diamond in a different way, place it under a UV light and watch the reaction. Most diamonds will emit a blue colored glow, but not all of them.
Some diamonds do not glow under UV light. When a diamond does this well and sparkles radiantly, it is called brilliance. Stones that are not diamonds, such as Cubic Zirconia, will not refract light as well. They will have less brilliance, if any at all. Ensure the lighting is bright and that no objects or people are casting a shadow on the diamond. If the diamond is real, its facets will refract the light in different directions, rather than in a straight line.
The newspaper test is most effectively used on loose diamonds. If the diamond is in its setting already, consider using the fog test or having it reviewed by a diamond expert. Place a white piece of paper on a flat surface and draw a small dot with a pen. Lay the stone onto the dot with the flat side down.
Through the pointed end of the diamond, look down onto the paper. If you see a circular reflection inside the gemstone, the stone is fake. If you cannot see the dot or a reflection in the stone, then the diamond is real. Because a true diamond has powerful refractive qualities, light will bounce in different directions instead of a straight line. In addition to refractivity, you can test a stone based on its reflectivity.
While refractivity pertains to the directions the light bounces, reflectivity refers to the amount and quality of the light that is reflected off of the stone. Hold the diamond in question under a normal lamp. Watch how light reflects off of the stone. Do you see bright shimmers of white light bouncing off the diamond?
All you need is a plate of glass and your diamond in hand. Set the glass on a platform, then scratch its surface using your diamond. However, it should be noted that this process could also damage the glass.
A quick and easy way on how to tell a real diamond from a fake is by fogging it with your breath. It should clear up after a second or two, proving your diamond is real. Diamonds instantly disperse heat, making it impossible to remain fogged. To perform this test, ensure your diamond is clean and free of oil stains and coverings.
If you have a real diamond with your suspect stone, perform the test on both. Observe how the real one remains clear, while the fake fogs over the as you breathe in it. The phony stone fogs up more and more, building condensation, while the real diamond remains clean and clear. This test stands out as one of the easiest tests, albeit non-conclusive. It is because the density of diamonds is very high. To perform this test, you need a glass of water and a diamond.
Drop your diamond in the glass of water. If it is real, it will sink to the bottom. If it is fake, it will float on the water surface. Keep in mind that not all fake diamonds float in water. Hence, you may have to perform further tests to know if it real or not. Diamonds are unresponsive to heat due to their incredibly strong material build. This method is also known as the heat test. You need a glass of cold water, a set of players or fireproof gloves, and a lighter to perform this test.
Heat the stone for about 40 seconds and immediately drop it directly into the cold water. If the stone breaks, it means that the diamond is fake because real ones would show no reaction.
This method shows the strength and quality of the stone. Weaker materials or gem such as zirconium crack due to continuous quick expansion and contraction caused by the heat. Consider Pyrex dish when cooking for example. If you try to wash it immediately after pulling it out of a hot oven, the dish may shatter due to a shock in temperature change. Diamonds being one of the strongest materials on earth, gives them resistance to such extreme heats. They can disperse heat quickly, so a change of temperature does little to affect them.
For this test to work, you need a newspaper and your diamond to be very clean. Place your diamond face down, with the pavilion facing up, in a section of the newspaper. If you can read the letter through the diamond, then your diamond is probably fake.
