The Treasure Gallery is a series of exhibition spaces in the northeast part of the Forbidden City in an area of the Museum known as the Palace of Tranquil Longevity Sector (Ningshou gong qu). It consists of six gallery rooms displaying pieces from the imperial collection and extant accoutrements for palace life. All of these exquisite items are made of precious materials, such as jade, jadeite, gold, silver, pearls, and other precious and semi-precious stones. The superb craftsmanship and inestimable value of each piece is aptly summarized in the title of the gallery. WANGDA SHOWCASES customized museum grade display cases for the new Galleries.
