The charm of diamonds lies in their incredible sparkle and beauty. But as lab-grown diamonds become more popular, many wonder if a jeweller can tell the difference between these and mined diamonds. James Sanders, the Managing Director of London Diamonds, explains how this works.
Understanding Lab-Grown Diamonds
Lab-grown diamonds are created in controlled environments that mimic the natural conditions under which diamonds form. They have the same physical and chemical properties as mined diamonds, making them nearly identical. But can a jeweller tell them apart?
Methods to Identify Lab-Grown Diamonds
- Microscopic Examination:
- Inclusions and Patterns: Jewellers use magnifying tools to look for tiny imperfections in diamonds. Lab-grown diamonds may have specific types of inclusions or growth patterns that can hint at their origin.
- Fluorescence Testing:
- UV Light Reaction: Diamonds can react to UV light by glowing. Lab-grown and natural diamonds might show different fluorescence patterns. However, this test is not always definitive on its own.
- Advanced Tools:
- Detector Machines: Some advanced machines are designed to distinguish between lab-grown and natural diamonds. They measure various light responses and other factors to determine a diamond’s origin.
