Highly lustrous, royal-blue to midnight-blue aggregates of azurite blades form a very showy, elongated, azurite "rose" from recent Chinese finds. This fine piece is a complete-all-around floater and is essentially pristine. Scattered bits of malachite (second photo) are a nice accent. Ex. Tarnowski Collection.

context_page_description: Daye is a county-level city in eastern Hubei province, China. It is under the administration of the Huangshi prefecture-level city.
  As it is usually the case with county-level cities, Daye includes both an urban core and a fair amount of rural land in all directions, with smaller townships such as Dajipu. According to the Fifth Population Census of China, the entire county-level city of Daye had 813,600 residents, with a population density of 558 people per square kilometer. The city is made up of 18 township-level divisions.
  The Daye Lake south of Daye's urban core is surrounded by parks and fishing ponds, and is a popular place for recreation.
  For a traveler who goes on G316 from Wuhan toward the south-east, Daye appears as a border between the more urban and more rural parts of the province. Daye sits on the south-eastern border of the heavily industrialized Wuhan/Ezhou/Huangshi metropolitan area; south of it, the much more rural Yangxin County begins.
context_section_description: Daye is an industrial city, a center of mining and metallurgy, both ferrous and non-ferrous; its name means 'developing a prosperous smelting industry' (大兴炉冶).
  Copper mining and smelting was conducted at Daye's Tonglüshan Mine (铜绿山, 30°04′52″N 114°56′07″E) as early as the Spring and Autumn period (6th century B.C.E.), if not earlier. Tonglüshan Mine is located just southwest of the modern city, and now has a museum.
  Although such copper-containing minerals as malachite and azurite are found here, the local ores are richer in iron than in copper, and the modern Daye is better known for its iron ore mining and processing.
  Among the major employers is Huangshi Daye Non-ferrous Metals Co., Ltd.
