Judging from the overall jade quality, there is a clear gap between the quality of the yellow pits in the old pit and the new pit. The yellow mouth material usually produced from old mines is mostly high-quality jade material. Its texture is thick and delicate, and the luster is lustrous. It is similar to Hetian Topaz; however, the quality of the new mine yellow mouth material is relatively poor, and most jade materials have a partial texture and toughness. Poor, and often contain defects such as impurities, pulp, white flowers, etc., so the overall quality of the yellow mouth material is far less than Hetian Topaz.
