Such pieces were traditionally created by Chinese artisans in the 20th century (sometimes in imitation of earlier periods) from semi-precious gemstones. Materials and Craftsmanship: Flowers and buds: carved from semi-precious stones and minerals (including quartz, agate, jade, or soapstone). Leaves and branches: carved from dark stone (jade or sodalite) on a wire frame.
