Among the jade collectors, except for jade and white jade, which are recognized as nephrite and jadeite, Huanglongyu, as a new jade, has attracted people's attention because of its warm and elegant color and rich color. Huang Longyu, originally known as "yellow wax", has a Mohs hardness of 6.5 to 7 degrees, a density of 2.6 to 2.7/cm, and a refractive index of 1.52 to 1.545. Huanglongyu is produced from the Longjiang River in the Xiaoheishan Nature Reserve, Longling County, Baoshan City, Yunnan Province. In addition, Zhejiang Longyou and Guangdong Taishan also have output. Huanglongyu is quite rich in color, its main color is yellow, and it has both white, white, red, black, gray and green. There are so-called "yellow gold, red as blood, green as green, white as ice, black as ink" Reputation. The main component of Huanglongyu is silica, which contains iron oxide, manganese or iron sulfide and a variety of micro-nutrients. The polycrystalline composite is similar to chalcedony and agate. It is endogenously oxidized and exogenous infiltrated. Naturally generated. Like Huangtianyu, Huanglongyu also has the distinction of mountain and seed materials. The mountain material is divided into “ç¡å‘石â€, “chicken pit stone†and “turf pit stoneâ€; the seed material is divided into “mountain stream†and “seed stoneâ€. Like Huangtianyu, Huanglongyu has a delicate texture and a silky texture. Many of them also have skin. The quality of the identified varieties is similar to that of jade, which is divided into gemstone species, ice species, oil species, skin frozen seeds, micro-crystal seeds, and snowflake species. The rating is “seed, water, color, net†as the standard, “species†refers to texture; “water†refers to transparency; “color†refers to purity and hue saturation; “net†refers to clarity. In 2004, when Huang Longyu was discovered and hyped, it attracted the attention of the domestic collectors, but the industry was mixed. The author believes that although Huanglongyu is a new type of jade, it not only has the warmth of Hetian jade, the color of Tianhuang, but also the hardness of jadeite. Since the official implementation of the “Jewelry and Jade Name†national standard in February 2011, Huang Longyu has been favored by jade collectors for its new jade species. At the same time, with the deepening of the collection of Huanglongyu, the enthusiasts also carried out a shallow to deep exploration, which produced various methods of identification and identification. It is believed that with the interpretation of the collection history, the value of Huang Longyu will gradually emerge. Unique shape Wang Xiaojing is a collector of Huanglong jade in Longling, Shanghai. Since 2008, she has collected and studied Huanglongyu. Among its collections, Huanglong jade with various colors and textures is almost all, unique in shape, exquisitely carved, and contains a profound folk culture. Now I will take 3 pieces of Huanglong jade carvings and introduce them to them. Huanglong jade carving "Panasonic asks the boy" ornaments This theme originated from the Tang Dynasty poet Jia Dao's "The Invisible Persons", the original poem: "Panasonic asked the boy, the teacher took the medicine. Only in this mountain, Yunshen did not know." Over the ages, this theme has been mostly loved by literati, or paintings, or sculptures, highlighting the essence of national culture. This piece is a mountain type, 14 cm high, 12.5 cm wide and 3.8 cm thick. It is a rare species in Huanglong jade seed. Appreciating the scenes in the works, whether it is landscapes or portraits, is just right, giving people an immersive feeling, showing the enthusiasm that the author has devoted to his creation. In addition, this jade is a rare variety in Huanglongyu, the texture is warm and the color is even, so it is very collectible. Huang Longyu "Huangshan Shengjing" decoration Huangshan is a famous tourist destination, and Huangshan's welcoming pine is a household name. This “Huangshan Shengjing†belongs to the water and grass material in the material of Huanglongyushan, and the jade scene is the formation of mineral intrusion in geological movement. This piece is 19 cm high, 30.5 cm wide and 3.6 cm thick. It is pure natural mountain shape, just slightly polished and polished. Meditate on this natural pattern, just like standing at the foot of the mountain and looking up at the mountains and the afterglow, I saw the towering cliffs, the ancient pines and cypresses, and the masterpieces of nature are really intoxicating. This is the precious thing of water and grass, so it is worth a lot. Huanglong jade carving "Hey Zizizi" ornaments The ornaments are mountain-like, 11.5 cm high, 21.5 cm wide, and 4 cm thickest. This theme should be the extension and expansion of the traditional story of "Hehe and Two Immortals" or "Good Money Boys", which implies the meaning of "harmony and harmony, and qi and wealth". The picture of this decoration consists of two parts. The upper part is the boy holding two ingots. The tender face is full of smiles. The lower two boys are holding lotus flowers, which seems to be playing with lotus leaves. The whole piece of the carved scene is quite quiet and quiet, full of a harmonious and peaceful atmosphere, and there is a visual impact of the static movement. Because of the unique texture of Huanglongyu, the decoration is more profound and noble, and its collection value is of course self-evident.
