Pucting information: This CMA, CAL, CNAS/CNAL Place the jadeite under the fluorescent light to observe its color changes. , White. C is dyed, so its color is distributed along the cracks, the distribution is uneven, and you can see the naked eye carefully. In the emerald is soaked by strong acid and alkali, the structure is loose, and the surface of the surface is performed on the surface before filling, making it a mana reflection and a weakened gloss. After adding people or plastics such as an organic charging, emerald often has resin luster, wax -like luster, or glass luster with resin luster and wax -like luster. Because the emerald structure is destroyed, the original optical properties have also changed, so "the color distribution of the jade expansion of the emerald is not layered. Although the green color of the jadeite handled by this method is still primary, after passing, it has passed through The acid solution is soaked, the base becomes white, the green distribution is relatively floating, and the orientation of the original color is also destroyed. It looks very unnatural.

Feeling a heavy feeling of pressing your hands, this may be the real jadeite. Fake emerald feels a kind of ethereal feeling when it is pressed down. This is a good way to identify medium emeralds. 2, identify through hardness: The real jadeite hardness is high. You can scrape the surface of the emerald with sharp nails or hard objects like a knife. If it is true emerald, the surface of the emerald will feel very slippery and will not leave any scratches. Fake emerald will scratch the surface with hard objects, leaving obvious scratches on the surface. 3, to identify by knocking out: You can use a rope to tie the jadeite, then pick up the rope with your hand, hang the jadeite in the air, and then gently knock the jadeite with a hard wood stick.
