Gadgets to take with you

The correct way to use a hand-held magnifying glass is to pick up the gemstone with your left hand, pass the index finger of your right hand through the hole under the magnifying glass, and rest your hands lightly on the cheek. This distance is the focal length of the 10x magnifying glass. The correct use of a hand-held magnifying glass can see the characteristics of the inclusions of a gemstone. В целом, consumers may find it difficult to verify the authenticity due to lack of experience, but this method can be used to better understand your gems.
