Qingtian stone variety identification method
Qingtian Stone Variety Identification Method:
Among the famous varieties of Qingtian Shizhong, the most renowned are the "Pushing Light" type, followed by Blue Flower Qingtian, Fengmenqing, Zhuyeqing, Mustard Green, Jinyu Frozen, and Golden Yoke. Other unique stones include Dragon Eggs, Three-Color Seals, Frozen Plates, and Red Sandalwood Flowers.
The "Pushing Light" variety features a pale yellow color with a translucent, jade-like quality, known for its smooth texture and clarity. It is mainly found in the mountain pass region of Qingtian, making it highly sought after by collectors.
The "Blue Flower" or "Green Gate" variety has a light blue tone, slightly transparent, and an extremely fine texture. In addition to its characteristic blue color, it often displays delicate, thread-like patterns within the stone. However, many local stone merchants now use Liaoning Kuandian stone as a substitute. While Kuandian stone is also fine and transparent with good luster, it can be distinguished by its slightly yellowish-green hue, more vibrant color, and the presence of light-colored crepe-like structures. It is also harder to carve than genuine Qingtian stone.
Dragon Eggs, commonly referred to as "Rock Eggs," are a rare and unique type of stone found in Zhoucun. They have a hard, dark brown outer shell that encases valuable green and yellow frozen stone inside. These stones are highly prized due to their rarity and beauty. In recent years, some imitations have been created by adding a deep purple rock layer on top of the green and yellow frozen stone to mimic the appearance of a real Dragon Egg. However, these fake stones often show unnatural layers, with visible signs of resin bonding between the different colored sections. Additionally, there are no natural signs of symbiosis between the frozen stone and the darker outer layers, which helps experts identify fakes.
