How Do Lab Grown Diamond Testers Work?

Hello, and welcome to Acredo's blog! You may have heard about lab-grown diamonds, a remarkable innovation that combines ethical sourcing with the timeless allure of these precious gems. But how can you be sure that your diamond is authentic, whether it's traditionally mined or made in a lab? That's where diamond testers come in.

What are Lab-Grown Diamonds?

Lab-grown diamonds are crafted with a unique combination of heat, pressure, and carbon - just like natural diamonds. The difference lies in their origin. Instead of forming deep in the Earth over billions of years, lab-grown diamonds are created within weeks in a specialized laboratory environment. This remarkable process provides an ethically sourced and sustainable option for diamond lovers, without compromising on quality or brilliance. Here at Acredo, we offer a wide range of custom-designed, lab-grown diamond jewelry, allowing you to express your individuality while embracing sustainability.

How Do Diamond Testers Work?

Diamond testers are nifty little devices that determine the authenticity of a diamond. They work by measuring the rate at which heat moves through a stone - a property known as thermal conductivity. Real diamonds have high thermal conductivity, meaning heat passes through them quickly, while most diamond simulants do not. In this way, diamond testers can identify real diamonds from fakes.

Challenges in Testing Lab-Grown Diamonds

Testing lab-grown diamonds is a bit more complex. Since they have the same physical and chemical properties as natural diamonds, a standard diamond tester will identify them as real diamonds. However, to differentiate between a lab-grown and natural diamond, more advanced testing is needed. At Acredo, we use the most advanced technology to ensure the authenticity and quality of our diamonds. You can trust that your handcrafted jewelry from Acredo will feature only the highest quality lab-grown diamonds.

Types of Lab-Grown Diamond Testers

There are two main types of diamond testers used for distinguishing lab-grown diamonds from natural ones: spectroscopic testers and luminescence testers. Spectroscopic testers analyze the light absorbed by a diamond, while luminescence testers measure the light emitted from a diamond when exposed to UV rays. Both these techniques can provide valuable clues about a diamond's origin.

Techniques to Improve the Accuracy of Lab-Grown Diamond Testing

Advanced diamond testers are invaluable tools for Acredo's commitment to ethical sourcing and transparency. Our highly trained experts use these testers alongside other identification methods, like microscopes, to provide you with personalized consultations and ensure that you're getting a true lab-grown diamond.

The Future of Lab-Grown Diamond Testing

As technology continues to advance, so too will the methods of testing lab-grown diamonds. More accurate and accessible testing techniques are being developed, which will allow even greater assurance of a diamond's authenticity. These advances will also further solidify Acredo's commitment to providing exceptional customer experiences and maintaining the high ethical standards outlined by the Responsible Jewellery Council.
