Which area in Myanmar is known as the center of the jadeite-mining district?

Hpakan is recognized as the center of the jadeite-mining district in Myanmar. This area is particularly significant due to its rich deposits of jadeite, which is highly valued in the gemstone market. The jadeite mined in Hpakan is renowned for its quality and is sought after by jewelers and collectors worldwide. This mining district has a long history of jade production, and the region's geological conditions are conducive to the formation of this precious stone.

In contrast, while Mandalay is a major city and cultural hub in Myanmar and does have connections to the jade trade, it is not the primary mining location. Yangon and Bagan are also notable locations in Myanmar but are primarily involved in different industries, such as commerce and tourism, rather than jade mining. Thus, Hpakan stands out specifically for its jadeite resources.
