Dushan jade is named after Dushan, about 8km northeast of Nanyang City, 河南省, and is also called “Nanyang Jade”. It is a kind of zoisite plagioclase, belonging to multi-color jade, referred to as “du jade”.
Duyu has bright colors, complete patterns, both shades, fine texture, dense and hard, Mohsの硬度 6-6.5, glass luster or grease luster, opaque, 半透明にわずかに透明, and a few high-quality products are close to transparent.
それで, how long is the mining history of Dushan jade?
Dushan jade has a long history of being mined and used. According to the textual research of the cultural relic “Nanyang Jade Shovel” unearthed from Huangshan Mountain in Nanyang County, it should belong to the Neolithic Age, について 6,000 数年前. According to the records of my country’s first chronological history “Han Shu”, Shagangdian Village at the foot of Dushan Mountain was called “Yujie Temple” in the Han Dynasty. It was the place where jadeware was produced and sold at that time, and it has a history of more than 2,000 年.
Duyu has an important historical position in our country. As early as five or six thousand years ago, ancient people had begun to use duyu. Among the jade artifacts unearthed in the “Yinxu”, there are many duyu products.
Duyu is one of my country’s “Four Famous Jade”, and its output exceeds Hetian jade and turquoise, and ranks second among the “Four Famous Jade”.
The emerald green variety of high-end single jade is somewhat similar to the emerald green Burmese jade, so it is called “Nanyang jade”. しかし, the jade quality (構造, transparency and luster) and emerald green color of Duyu Jade is hard to compare with high-quality Burmese jade. 例えば, a high-end single jade bracelet can be worth more than RMB 10,000, while a high-end jade bracelet can be worth more than 5 百万元. Stone jewelry: high-quality turquoise is mainly used to make egg-shaped ring faces, breast pendants, イヤリング, 等; ordinary turquoise is used to make various styles of necklaces and other accessories, which are mainly sold in the domestic market.
