Turquoise is one of the four famous jade in my country, and it is a traditional jade material that is deeply loved by people. According to archaeological data, turquoise was early in the Neolithic Age; it has been exploited by people. Turquoise fish-shaped ornaments were unearthed from the Yangshao Culture site in Dahe Village, Zhengzhou, 허난성 (~에 대한 6,500 에게 4,000 여러 해 전에). The English name of turquoise is “Tur-quoise”, which comes from French and means “터키 옥”. 현재, people in Taiwan still call turquoise “터키 옥” 또는 “turquoise jade.” 사실은, 터키에서는 청록색을 생산하지 않습니다., but because the turquoise produced in ancient Persia had to pass through Turkey to enter Europe. When Princess Wencheng of the Tang Dynasty entered Tibet, she brought a lot of turquoise. Because of its unique color, 조직, and wire mesh pattern, turquoise has been deeply loved by Tibetans ever since.

Turquoise belongs to the triclinic crystal system, with a cryptocrystalline structure, which can have oolitic, kidney-shaped, tuberculous, vein-shaped and dense massive structures. In turquoise, there can be symbiotic minerals such as kaolinite, 석영, 운모, and limonite. The color of turquoise is mainly blue and green, and it can also have variegated colors such as yellow, ocher and off-white, often with white spots and brown black iron wire. The sky blue is caused by the bivalent copper ion, and the green is closely related to the ferric ion. Aluminum ions in turquoise can be partially replaced by iron ions. As the content of iron ions increases, the color of turquoise changes from sky blue to green or earthy yellow.

Turquoise has a shell-like fracture, waxy luster or grease luster. The refractive index is usually 1.61～1.65, the density is 2.40 g/cm3-2.90 g/cm3, 일반적으로 2.76 g/cm3, and the Mohs hardness is 5-6.
