You mean jewelry appraisal, right? You can take pictures with a professional jade flashlight. My dad used a tourist flashlight, which I remember as J6. The effect is still very good. I Baidu searched the parameters for you.

1.J6 is a special flashlight for jade identification. The light source is CREE LED (yellow light and white light optional) imported from the United States, with strong penetration. It is a powerful tool to identify jade and antiques, and also a good helper for experts, jewelry shopkeepers and antique lovers to identify.

2. The pen container is designed to be portable.

3. The fuselage is made of aviation grade aluminum alloy, and the head and tail are made of 304 stainless steel, which shows noble quality with harmonious color matching and is more wear-resistant and difficult to change color.

4. The button switch at the back is convenient and practical, with handstand function.

5. Using orange peel aluminum alloy reflective cup, the light beam is softer and the light spot is more uniform.

6. Constant current circuit chip/constant brightness, two-step dimming, brightness can be adjusted as needed.

7. Anti-reverse connection protection circuit design, don't worry about reverse connection of the battery to the product.
