How can you tell if something is a real diamond

Visual Inspection Methods

Visual inspection is your first line of defense against fake diamonds. A real diamond has specific visual characteristics that are difficult to replicate perfectly.

When examining a potential diamond, look for its brilliance and fire. Real diamonds reflect light in a unique way, creating that famous sparkle that seems to contain all the colors of the rainbow. This occurs because of a diamond’s high refractive index and excellent light dispersion properties. When shopping for engagement rings in Fresno, CA, pay attention to how light dances through the stone.

Another visual indicator is clarity. While not all real diamonds are flawless (in fact, most have some inclusions), these imperfections typically appear as tiny crystals, clouds, or feathers inside the stone rather than scratches on the surface. Surface scratches often indicate a less durable simulant.

The cut of the diamond also matters. Professionally cut diamonds have precise, symmetrical facets that contribute to their brilliance. Irregular or asymmetrical faceting might suggest you’re looking at a fake. Our collection of rings in Fresno, CA features diamonds with exceptional cuts.

Lastly, check the setting. Genuine diamonds are typically set in high-quality metals like platinum, gold, or silver. If the setting appears cheap or is showing signs of discoloration, it might indicate that the stone is also of lower quality.

The Water Test

The water test is a simple but effective method to test diamond authenticity based on density. Diamonds have a high density, which affects how they behave when placed in water.

To perform this test, fill a glass with water and gently drop the stone into it. Due to their high density, real diamonds will sink to the bottom immediately. Most diamond simulants, including cubic zirconia, will also sink, but some fakes like quartz or glass might float or sink more slowly.

While this test won’t definitively separate diamonds from all simulants, it can help eliminate certain obvious fakes. For more certainty, visit us at our jewelry store in Fresno, CA, where we can provide professional testing.

Remember that this test should only be performed with loose stones or securely set jewelry to prevent loss. If you’re testing a piece from your collection of bracelets in Fresno, CA or other jewelry, ensure the stone is firmly set before attempting this test.

The water test is just one preliminary screening method and should be used alongside other testing methods for a more accurate determination of diamond authenticity.

The Fog Test

The fog test utilizes a diamond’s ability to disperse heat quickly to distinguish it from imitations. This simple test can be performed anywhere and requires no special equipment.

To conduct the fog test, hold the stone between your fingers and breathe on it like you would fog up a mirror. A real diamond will disperse the heat from your breath almost immediately, causing the fog to vanish instantly. Imitations like cubic zirconia and glass retain heat longer, so the fog will remain for several seconds.

Diamonds are excellent thermal conductors, which is why they don’t stay fogged for long. This characteristic is also why diamonds feel cool to the touch, unlike many simulants which quickly warm to body temperature. When choosing diamond earrings in Fresno, CA, this property ensures your diamonds always feel cool against your skin.

While the fog test is convenient, remember that moissanite (a popular diamond alternative) also disperses heat quickly and may pass this test despite not being a diamond. For a comprehensive assessment, combine this test with others or consult professionals at Gobind Jewelers for our jewelry in Fresno, CA expertise.

Regular cleaning of your diamond jewelry is important as oils and dirt can affect the results of this and other tests. Maintain your precious stones with proper care to preserve their beauty and value.

The Newspaper Test

The newspaper test exploits the high refractive index of diamonds to help identify genuine stones from imitations. This test is particularly useful for loose diamonds but can also be applied to certain mounted stones.

To perform this test, place the stone flat side down on a piece of newspaper with text. Look through the pointed end of the diamond at the print. If you can read the letters through the diamond, even if they appear blurry, you likely have a fake. Real diamonds bend light so significantly that you shouldn’t be able to see through them clearly enough to read text.

This effect occurs because diamonds have a high refractive index of 2.42, which causes light to bend dramatically as it passes through the stone. This is the same property that gives diamonds in our wedding rings in Fresno, CA their exceptional brilliance and fire.

Some diamond simulants like cubic zirconia and moissanite also have high refractive indices, but they don’t bend light in exactly the same way as diamonds. The newspaper test isn’t foolproof but can provide valuable clues about a stone’s authenticity.

If you’re uncertain about the results or want confirmation about a piece from your collection of earrings in Fresno, CA, it’s always best to seek professional verification from certified jewelers like our team at Gobind Jewelers.

The Heat Test

The heat test leverages a diamond’s exceptional thermal conductivity and stability to distinguish it from imitations. However, this test should be approached with caution as it can potentially damage fake stones and jewelry settings.

For a safer version of this test, fill a glass with cold water. Using pliers, heat the stone for about 40 seconds, then immediately drop it into the cold water. A real diamond will not react due to its stability and thermal conductivity, while many fakes might crack or shatter due to thermal shock.

Diamonds can withstand extreme temperatures because of their molecular structure – they’re essentially carbon atoms arranged in a crystal lattice. This is why wedding rings for women in Fresno, CA that feature diamonds remain pristine through years of daily wear.

We must emphasize that this test is risky and not recommended for valuable or cherished pieces. Heat can damage settings, adhesives, and treatments on both real and fake stones. Additionally, some modern diamond simulants are also heat-resistant.

Instead of risking damage to your tennis necklace in Fresno, CA or other precious items, we recommend having your diamonds tested professionally using specialized equipment that doesn’t put your jewelry at risk.

The UV Light Test

The ultraviolet light test examines how diamonds react to UV radiation, which can provide clues about their authenticity. Most natural diamonds exhibit some level of fluorescence when exposed to UV light.

To perform this test, you’ll need a UV light (blacklight). In a dark room, shine the UV light on the stone and observe its reaction. Approximately 30% of natural diamonds will fluoresce blue under UV light, though the intensity varies. Some may display other colors like yellow, green, or red, while others show no fluorescence at all.

The presence or absence of fluorescence doesn’t definitively prove or disprove a diamond’s authenticity, but it can provide additional information. Many diamond simulants like cubic zirconia typically show no fluorescence or may fluoresce in different colors than natural diamonds. When selecting gold chains in Fresno, CA with diamond pendants, knowing about fluorescence can add to your appreciation of these natural wonders.

It’s worth noting that diamond fluorescence is complex and varies based on the individual stone. Some high-quality natural diamonds show no fluorescence, while some synthetic diamonds are engineered to display fluorescence similar to natural stones.

The Sparkle Test

The sparkle test examines how a diamond interacts with light, focusing on its brilliance, fire, and scintillation – qualities that make diamonds truly exceptional. While subjective, this test can help trained eyes spot differences between genuine diamonds and imitations.

Under normal lighting, observe how the stone sparkles. Genuine diamonds exhibit a unique combination of white light reflection (brilliance), colored light dispersion (fire), and the twinkling effect as the diamond moves (scintillation). The jewelry in Fresno, CA at our store is carefully selected to showcase these exceptional light properties.

Real diamonds tend to sparkle with gray and white light (brilliance) along with occasional flashes of spectral colors (fire). Most imitations like cubic zirconia display more rainbow-colored sparkles and less white light brilliance. Moissanite, another popular diamond alternative, often shows more colorful flashes and “double refraction” that creates a slight haziness not present in diamonds.

The cut quality significantly affects a diamond’s sparkle. A well-cut diamond from our selection of engagement rings in Fresno, CA will display more brilliance even if it has lower color or clarity than a poorly cut diamond of higher quality.

While this test requires some experience to interpret correctly, comparing stones side by side can help you start recognizing the unique optical properties of genuine diamonds. Visit our showroom to experience the difference firsthand and see why diamonds have captivated humanity for centuries.

Professional Diamond Testing Tools

While DIY tests provide preliminary insights, professional diamond testing tools offer more definitive results. These specialized instruments measure properties unique to diamonds that are difficult to replicate in simulants.

Diamond testers (thermal conductivity probes) are among the most common professional tools. These devices measure how quickly a stone conducts heat. Diamonds conduct heat exceptionally well compared to most simulants. However, moissanite can sometimes pass this test, which is why reputable jewelry stores in Fresno, CA like ours use multiple testing methods.

Electronic diamond testers that measure both thermal and electrical conductivity provide more accurate results. Diamonds conduct heat but not electricity, while moissanite conducts both. This combination test can reliably distinguish between these two materials.

Microscopes and loupes allow professionals to examine a stone’s internal and external features. Under magnification, natural diamonds typically have tiny inclusions that differ in appearance from those in synthetic stones or simulants. When you’re investing in bracelets in Fresno, CA with diamond accents, these inclusions can actually help verify authenticity.

Spectroscopes and other advanced instruments can analyze the optical properties and chemical composition of gemstones, providing definitive identification. These tests are particularly important when evaluating high-value stones for wedding rings in Fresno, CA.

At Gobind Jewelers, we invest in professional testing equipment and training to ensure the authenticity of every diamond we sell. We encourage customers to witness the testing process firsthand for complete peace of mind.

Common Diamond Imitations

Understanding common diamond imitations can help you make informed purchasing decisions and avoid misrepresentations. Each simulant has distinctive properties that differentiate it from genuine diamonds.

Cubic Zirconia (CZ) is perhaps the most widespread diamond substitute. Made from zirconium dioxide, CZ is colorless, hard, and optically flawless. However, it lacks the thermal conductivity of diamonds, appears more “perfect” than most natural diamonds, and its facet edges may appear slightly rounded over time. While CZ makes affordable fashion earrings in Fresno, CA, it doesn’t match a diamond’s durability or light performance.

Moissanite is a silicon carbide material that closely resembles diamond in hardness and brilliance. It has even greater fire (colorful light dispersion) than diamond, which can appear as excessive rainbow flashes. Originally discovered in a meteor crater, today’s moissanite is lab-created and has become a popular ethical alternative for
