When it comes to lab-grown diamonds, a common question that arises is whether they can pass a diamond tester. Diamond testers are devices used to distinguish between mined diamonds and synthetic or imitation diamonds. These testers typically work by testing the electrical conductivity of the material.
In the case of lab-grown diamonds, they are created using the same chemical composition and crystal structure as natural diamonds. This means that they share similar physical properties, including electrical conductivity. As a result, most lab-grown diamonds will indeed pass a standard diamond tester.
However, it's worth noting that not all diamond testers are created equal. Some older or less sophisticated models may struggle to correctly identify lab-grown diamonds. Also, new advancements in lab-grown diamond technology have enabled the creation of diamonds with slightly different properties that may yield varied results on some diamond testers.
To ensure accuracy, it is recommended to use testing methods that are more comprehensive, such as those performed by professional gemological laboratories. These labs use advanced techniques such as spectroscopy and microscopic analysis, providing more definitive results. All diamonds we sell at The Cut Jewellery are fully certified - which means they already arrive having been sent for independent evaulation.
In conclusion, lab-grown diamonds are designed to have similar physical properties to natural diamonds, including electrical conductivity. As a result, most lab-grown diamonds will pass a standard diamond tester. However, for more accurate and comprehensive testing, it is best to rely on professional gemological laboratories.
