Since diamonds are rare and expensive, scams and fraud are prevalent. The news routinely shows with victims of these heartbreaking crimes. Some men unknowingly buy fake diamond jewelry for their loved ones. Meanwhile, misled women wear plastic rings thinking that these have value.
You should be careful if you want to buy diamonds. One marker of authenticity is the symbols on the jewelry. Make sure that their labels are correct, following the conventions of diamond manufacturers and vendors. These are the hallmarks for diamond rings:
As you can see, crafters can assign different markings to describe the jewelry’s quality and prestige. But carefully assessing these symbols can save you from fraud and fake diamonds. Check their consistency and accuracy. Most importantly, buy diamonds from well-known vendors and respected sellers.
Identification diamond symbols stamped on jewelry can show the jewelry’s background and integrity. But there is a much more effective way of knowing the diamonds’ authenticity: checking the diamonds themselves.
Diamonds can now get created in laboratories. To achieve this, scientists expose carbon to harsh temperatures and pressure similar to the Earth’s mantle. But the result, synthetic diamonds, have a far lesser value than natural ones. At face value, mined and lab-made diamonds look alike.
Hiring a professional can help verify them. Experts know that synthetic diamonds have uniform structures and other elements aside from carbon.
Moissanite closely resembles diamonds, but it has a far lesser value. This stone is more sparkly, colourful, and refractive. Try letting light pass through it. If the stone becomes a prism of colours, that is not a diamond but moissanite.
Before purchasing diamonds, make sure that they do not belong to rocks like these. Doing so can help you sell diamonds at the price they deserve.
A fog exam is a proven way to test if diamonds are fake or not. Try breathing into the stone, like in a mirror. Then, watch the fog. If the moisture stays for many seconds, the diamond might be fake. Repeating this will make the surface even moister.
Authentic diamonds can spread out heat, so they do not condensate easily. It will stay clear from moisture even if you breathe into it again and again.
If you go to a jewelry shop, you will notice how vendors use loupes or magnifying scopes into the stones. Zooming in, you will see that authentic diamonds have tiny bits of minerals and quaint specks of colours. These imperfections are present because diamonds assemble in intense environments underground.
However, this does not happen to synthetic diamonds such as cubic zirconium. Yes, these lab-made stones can pass other tests, but their perfection incriminates them. Synthetic diamonds came from controlled and sterile productions, unlike natural ones.
Microscopes can also help determine the diamond’s authenticity. While looking at the lens, move the diamond slowly. If there is something orange on its surface, that is likely cubic zirconia or synthetic diamond. Hence, it does not have the same price and quality that natural diamonds possess.
Another crucial property that authentic diamonds have is their greyish reflection. Gaze from the diamond’s top part. If it shows a rainbow of colours, the stone might be fake. Moreover, real ones have the same brilliance as glass. If it is too shiny and vibrant, the stone might be moissanite.
Diamonds are the most durable and resilient materials on Earth. This stone can quickly withstand heat, given its intense origins. To test its authenticity, an expert might expose the diamond to heat for 30 seconds. Legitimate diamonds will only absorb the heat. But fake ones will break, melt, or abnormally warm up.
However, moissanite has the same heat dispersing property that diamonds have. An electrical test can differentiate the two.
Diamonds can stay hidden from x-rays because of their molecular properties. So if the stone reflects an image on an x-ray, it is a fake. Perhaps, that false diamond is only a piece of glass or crystal.
You can consult a testing laboratory or an imaging centre to conduct this diamond test.
Understanding identification diamond symbols can guide you in assessing jewelry. But determine if the stamps are consistent with the material and the official seals. To be sure, test the diamond itself to prove its authenticity.
