6 Proven Ways To Identify Fake Diamond Jewellery

Diamonds are one of the most valuable and sought-after gemstones in the world. However, with their high price tag, there has been a rise in the production of fake diamond jewellery. Identifying fake diamond jewellery can be difficult, especially if you’re not an expert in the field. In this blog, we’ll be discussing how to identify fake diamond jewellery and the common methods used to create fake diamonds. By the end of this article, you’ll have a better understanding of how to identify real diamonds and avoid being scammed by fake diamond jewellery.

1. Look for imperfections

Real diamonds are formed naturally and often have small imperfections or inclusions. If a diamond appears perfect and flawless, it may be fake. A fake diamond may also have air bubbles or scratches, which are not typically found in real diamonds.

2. Conduct a water test

Diamond Water Test

This is a simple test that involves placing the diamond in a glass of water. If the diamond sinks to the bottom, it’s likely a real diamond, but if it floats or is suspended in the water, it’s likely fake. This is because real diamonds have a high density, so they will sink in water, while fake diamonds are often made of lighter materials and will float.

3. Check for heat conductivity

Diamond Heat Conductivity Test

Diamonds are known for their high thermal conductivity, which means they disperse heat quickly. To test for this, hold the diamond under a flame for a few seconds, and then immediately touch it with your fingertip. If it’s a real diamond, it will disperse the heat quickly, and it will feel cold to the touch. If it’s fake, it will not disperse the heat as quickly and may feel warm or hot to the touch.

4. Look at the mounting

Diamond Mounting Test

If the diamond is mounted in a piece of jewellery, take a close look at the mounting. Real diamonds are often set in high-quality metals like gold or platinum, while fake diamonds may be set in cheaper metals like brass or copper. The mounting should also be smooth and well-crafted, with no signs of rough edges or gaps.

5. Use a diamond tester

Gold is a dense metal, so it should feel heavy for its size. If your jewellery feels light or flimsy, it may be fake. This test involves weighing the piece of jewellery and then calculating its density based on its dimensions. A trained professional can perform this test, but it may not be practical for the average person to do it on their own.

6. Get a professional opinion

If you’re still unsure about whether a diamond is real or fake, you can take it to a professional jeweller for an appraisal. A professional can examine the diamond using specialised equipment and can tell you definitively whether it’s a real diamond or not.

Wrapping Up

In conclusion, while fake diamonds can be difficult to spot, using the above methods can help you determine whether a diamond is real or fake. It’s important to remember that some fake diamonds can still pass these tests, so it’s always best to have a professional jeweller examine the diamond if you have any doubts about its authenticity.
