intricately carved in openwork with a dragon entwined within a dense network of leaves and peony blossoms, supported on an oval base pierced with four small apertures

There are minute expected bruises and nicks to the edges and fragile openwork extremities. Sections have also possibly been lightly polished to conceal an earlier nick, especially to the edges of the base. The finial is otherwise in overall good condition.
