Ancient emperors wore many kinds of jewelry, the most common of which were jade, precious stones and gold and silver vessels. In the court of the Qing Dynasty, the emperor and officials wore beads around their necks as early as the early dynasty, and there was a set of strict wearing standards (especially for the emperor). The emperor's beads are made of lapis lazuli beads, amber or beeswax beads, coral beads and turquoise beads. In addition, the Palace Museum has a collection of about 30,000 ancient jade articles, mainly from the remains of the Qing Palace. Most of these jade articles are jade articles, and the rest are made of precious stones such as crystal, agate, lapis lazuli, hibiscus, malachite and coral, with complete varieties and exquisite workmanship.
