The Shandong Changle sapphire mining area is located in the Changle sag of the Taibei uplift in the northwest of Shandong Province, and the 鄌郚-Gegou fault in the east is adjacent to the Tanlu fault zone. The Neogene Tertiary volcanic rocks are widely distributed in the mining area. Among them, the Miocene Niushan Formation is mainly altered basalt, almond-shaped basalt, olive basalt, and a small amount of glass-based basalt rock, which forms a flat lava platform on the topography; The mountain group is distributed at the top of the volcanic body and is the main part of the volcanic cone. The lithology is black and later olive basalt, and the columnar joints are developed with a small amount of glass-based basalt and high-aluminum basalt. The sapphire primary ore is stored in the center of the volcanic eruption. Its host rock is Bolivia sapphire rock, SIO2 is unsaturated, less than 45%, and it is a sodium series, which belongs to ultrabasic rocks. The host rock contains deep source trapping bodies and trapping crystals. Alkaline olive basalt contains sapphire, but it contains very little. The Quaternary of various genetic types in the area contains sapphire, but the gravel layer at the bottom of the impact layer and the accumulated debris on the bedrock surface are mainly for the base layer. The sapphire is formed in the upper mantle of about 100KM below the earth's crust. It is from the depth of the sapphire crystal environment. The basaltic magma contains sapphire. The Linfen fault zone along the deep mantle rises rapidly and forms an olive basalt-type sapphire primary deposit. The original mine is in the area of ​​Fangshan. Due to long-term weathering and erosion, the slope forms a slope skirt. The basalt is only prominent within tens of meters from the top of the mountain. The middle and lower parts of the slope are mostly covered by debris, slopes and Quaternary. The sapphire mine is divided into two types: primary ore and ore. The primary ore is located in the basalt near the mountain at 30M, while the sand is distributed in the macro and impact areas near Fangshan. The area is mainly distributed in Changle County. The map, Qiaogong, Nanhao, Cuijia and Beiyan areas are mainly modern riverbeds, which are also distributed in ancient riverbeds, hills and farmland. The sand mines are layered and buried shallow, with a maximum buried depth of 10M, which is easy to mine. Changle sapphire ore is one of the four major producing areas of sapphire in China. The sapphire is mainly composed of sand mines, and is rich in 2M~4M floating soil layers and ancient riverbeds. The primary minerals are in the Tertiary alkaline basalt, mainly composed of sapphire, and occasionally ruby ​​and golden sapphire. Changle sapphire crystal particles are large, crystallized intact, mostly transparent, high yield rate, colorful colors, mainly blue, followed by yellow-green, other colors such as: rose red, golden, light yellow and tan, etc. The surface of the raw material is mostly covered by a layer of gray-black or black opaque thin shell, and the coating layer is mostly amorphous, which is caused by the sapphire being eroded by the lava and rapidly cooled. Although sapphire belongs to the higher grade gemstones in China, the color of Shandong sapphire is usually very deep, the transparency is low, and it is even black in appearance. The worn ring face is poorly fired or even anti-fire, which greatly affects Its viewing and economic value. Therefore, people have been trying to reduce their color. There are many studies in this area, but because the color is caused by a large amount of iron inside, the color change effect has been unsatisfactory, some colors have become lighter after color change, but the gray tone has increased, and some have greatly reduced the transparency. . Therefore, so far, the sapphire color treatment program has not been so good, so that its process value is greatly reduced.
The Cord Embroidery Fabric is normally made on poly mesh fabric(mono mesh.poly korean mesh).The products is in soft handfeeling and suitable for children dress.evening party dress .garment dress etc.
We always shipp them to American.European and Turkey etc.Most of these designs are designed by ourselves and you will see that it't very popular and pretty which is really popular in the market.
