T-stone Jade Co., Ltd is a professional company specialized in high quality Chinese Jade and Stone Carvings as Dushan jade, Hetian jade. Chinese Jade and Stone Carvings The term 'Jade' and its Chinese name yu, are often used to designate many different stones and glossy materials. While the name Jade in the west is mostly limited to refer to the minerals jadeite and nephrite, the Chinese Jade (Yu) is a wide concept covering almost any finely worked ancient mineral artifact. The materials that occur are ranging from relatively hard minerals such as agate and crystal and all the way to marble and soapstone. Despite the confusion it could be argued that the proper definition of Chinese Jade should reflect the use the word 'Yu' have in the Chinese culture. The two most typical 'Jade' minerals are Nephrite, which is a silicate of calcium and magnesium. That has been worked in China since the Neolithic period when it was brought in from Central Asia. Jadeite on the other hand, is a silicate of sodium and aluminum with a different crystal structure. It is slightly harder than nephrite. Jadeite do not seems to have been much used before the Qing dynasty when it by the end of the 18th century was brought in from Upper Burma. While both nephrite and jadeite are found in a range of different colors, depending the presence of small quantities of iron, chromium or magnesium, the brilliant green stones used in fine Chinese jewelry are jadeite. Most of the small colorful and glossy stone figures we find are traditional dress ornaments and good luck symbols from the 18th century and later. Due to its hardness it was considered good protection to carry a pieces of Jade on your body, If the Jade was worked into the shape of a turtle, with its hard shell, that would offer even better protection. Modern souvenir trinkets abounds, made in all kinds of materials, inclusive of glass, so some care is recommended studying the workmanship which tells what is good or not.
