Look at jade gambling stones and wool. The yellow flashlight is mainly used to "see cracks and cotton". Remember not to turn on the light to see the color. The color of emeralds darkens in yellow light. Low heart.

Jade products should see white light, especially Cui Mo, which is the only color. When you look at dark green, the yellow light will be very bright.

Flashlights see more jade and the quality is uneven. Tens of dollars to thousands. The actual difference is not very big, mainly the color difference. Just pass the quality test.

I use a Jinfudi emerald flashlight, which is of good quality, but expensive. LED lights are close to sunlight. Much better than a hundred.

High-end jadeite rivals have high demand for electromechanical products because the price difference is ten times, which is cheap and easy to choose.
