Sugilite, whose scientific name is Na-Li Dajiushi, is mainly composed of Sugilite. 1960s, Japanese geologists discovered a new kind of ore, which only originated from China, South Africa, Japan, Canada and the United States.
Everything is easy. Large-scale sphalerite was discovered in South Africa. It became a commercial variety in the 1970s. The colors of Sugilite are obvious dark blue, red purple and blue purple, and sometimes there are several different shades on ribbons and spots. Sugilite is usually yellow-brown, light pink and black, but these are rarely used in jewelry.
Generally, sugite is translucent to opaque, and gem-grade sugite is bright and translucent, which is similar to high-quality chalcedony, but it is difficult to obtain. Sphalerite has a glass-to-resin luster (waxy luster), and gems are often dotted with black, brown and blue linear manganese-containing inclusions.
Sugilite (English name: Sugilite), also known as the "Millennium Stone", is also the lucky stone for the February birthday of the Gregorian calendar. Sphalerite is a rare gem, known as the "national treasure of South Africa", which is produced in small rock beads of aegirine syenite. Its main component is silicon dioxide, which contains many metal elements such as potassium, sodium, iron and lithium.
1944 was discovered by Japanese oil explorer Mr. Sugiyama Kenichi, so it was named after him. However, it was not until 1979 that South Africa discovered gem-grade sugilite due to the collapse of some manganese mines in wiesel. The quantity found at that time was about 5 tons, of which 360 kilograms could be used as gems.
