Alexandrite is a precious gemstone due to its unique color-changing properties and rarity, but there are many imitations and counterfeits on the market. To ensure that the Alexandrite you buy is genuine, here are some ways to tell if an Alexandrite is real.
1. Observe the color change
Real Alexandrite can show significant color changes under different lighting conditions. It usually appears bluish-green in natural light and changes to reddish-purple under yellow light. If you see a stone with a subtle color change, it may be a fake.
2. Check for inclusions
Natural Alexandrite may have tiny inclusions (inclusions) inside it, which can be other minerals or bubbles. Use a 10x magnifying glass to carefully observe the inside of the gemstone. If you find obvious natural inclusions, it is more likely to be authentic. On the other hand, if the inside of the gemstone is clean, it may be a fake that has been artificially treated.
3. Luster and cut
Real Alexandrite has a high lustre and excellent cut, and can reflect a beautiful light under the light. Observe whether the gemstone is finely cut and has smooth edges. If the workmanship is rough, it may be a cheap imitation.
4. Weight and hardness test
Alexandrite has a hardness of 8.5 (Mohs hardness), which is very hard. You can use a small stainless steel knife to gently scratch the stone. If it leaves a scratch, it means that the gemstone may not be Alexandrite. In addition, real Alexandrite has a higher density and feels heavier than other gemstones.
5. Professional appraisal
You can ask a professional jewelry appraiser to evaluate it. With professional equipment and technology, they can provide more accurate appraisal results to help you determine whether the Alexandrite is real.
