How can you tell the difference between a diamond and a zircon?

Cubic zirconia is more likely to be completely colorless which is a tell-tale sign it isn't a diamond. Another notable difference is that a diamond will have natural inclusions throughout the stone which is a sure sign it is real. These inclusions can usually only be seen under a microscope.

How can you tell a diamond from a zircon?

The best way to tell a cubic zirconia from a diamond is to look at the stones under natural light: a diamond gives off more white light (brilliance) while a cubic zirconia gives off a noticeable rainbow of colored light (excessive light dispersion).

Does zircon look like diamond?

Zircon comes closer to resembling diamonds than any other natural gem. Its superior luster and intense fire give it a real sparkle that is comparable to a diamond. However, its popularity is somewhat diminished by the fact that it is often perceived as an inexpensive diamond imitation.

What is the difference between zircon and diamond?

Looking at both stones under natural light, diamonds show a strong white light (the diamond's “fire” or “brilliance”) whereas cubic zirconia gives off much more colored lights (the “rainbow effect”), as cubic zirconia has a lower refractive index and higher dispersion rate than diamonds.

How can you tell real zircon?

The most obvious way to distinguish a zircon presented as a substitute diamond from an actual diamond is by the former's birefringence. Zircon's high birefringence makes this 4.57-ct round brilliant-cut stone appear fuzzy.

Cubic Zirconia VS Diamond | How to Tell if a Diamond is Real

How do you tell if a diamond is real with a flashlight?

Simply hold the loose diamond near a light source, like a lamp, and see the reflection of the light from the diamond. This test will be best if there is another gem that you'll compare along with it, like cubic zirconia. You'll see how different their effects are to light.

How can you tell if a diamond is real at home?

This one's easy: Get a glass and fill it with water (it doesn't matter what type of water you use). Drop the diamond into the glass of water. Due to the high density of diamond, when dropped into water a real diamond will sink. If the diamond floats to the top or middle of the glass, it's fake.

How do I know if I found a diamond?

The only hardness test that will identify a diamond is scratching corundum. Corundum, which includes all rubys and sapphires, is 9 on the hardiness scale. If your suspected diamond crystal can scratch corundum, then there is a good chance that you found a diamond. But NO OTHER HARDNESS TEST will identify a diamond.

How do you know if it's a diamond?

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.

What is zircon worth?

Prices depend on color saturation, clarity and size. Fine saturated blues in sizes over 10 carats are typically $300 to $400 per carat, while high quality stones in the 5 to 10 carat size sell for $200 to $300 per carat.

Does white zircon sparkle like a diamond?

If you love diamonds, but not the associated cost, white zircons are an excellent alternative. These stones possess a similar dispersion to diamond, and the double refraction gives you even more sparkle.

Does zircon turn green?

Authentic Cubic Zirconia does not turn your skin green; however, a low-quality imitation might be because it has brass and copper inclusions. Some Cubic Zirconia has gold, silver, or rhodium plating on the bands, which means it tarnishes and makes skin green when the plating wears off.

Can the average person tell the difference between cubic zirconia and diamond?

You can easily tell the difference between the two if your measurements are correct and if you are using a standard scale. Another differentiating feature is that diamonds are the hardest substances found in the world. Their hardness is around 10 on the Mohs scale.

How do you test a diamond with water?

Get a glass full of water and simply drop your diamond into the glass. If the diamond is real, it will drop to the bottom of the glass due to the high density of the stone. If it's a fake, it will float on the surface of the water.

Do diamonds reflect light?

We all love how a diamond shines in the sunlight. Test your stone by putting it in direct sunlight and examining the colors it reflects. A real diamond will reflect both rainbow colors as well as white light. If you only get one of the two, then the diamond isn't real.

How should a real diamond sparkle?

The way that diamonds reflect light is unique: the inside of a real diamond should sparkle gray and white while the outside should reflect a rainbow of colors onto other surfaces. A fake diamond, on the other hand, will have rainbow colors that you can see inside the diamond as well.

Is there an app to test diamonds?

Now you can detect the authenticity of Diamonds and Gemstone through an App. Khanna Gems has launched a comprehensive mobile app available on both iOS & Android Platforms.

How can you tell a fake diamond?

Black Light Test

To conduct the test, turn off all the lights and put your stone under the source of black light. If you're holding a genuine diamond, you'll witness an intense blue color on the diamond surface. A fake gemstone will reveal itself through other colors — including green, yellow, or gray tints.

Do diamonds glow under UV light?

You will see a glow in 30% of diamonds under a uv light. When exposed to uv light, there will be a diamond glowing different colors. 99% of the time, the glow is blue, but on rare occasions, diamonds glow white, yellow, green, or even red in color.

How can you tell if a diamond is in the dirt?

Can you break a diamond with a hammer?

To say something is “hard” is not the same as saying it is “strong”. As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the hammer is strong. Whether something is hard or strong depends on its internal structure.

Will a real diamond scratch a mirror?

Glass is rated a 5.5, and diamonds, the hardest mineral, are a 10. So, genuine diamonds will scratch a mirror. On the other hand, so will quartz (7), moissanite (9.25), and cubic zirconia (8).
