Excavation of the south mound of Hwangnam Daechong (Great Tomb of Hwangnam) unearthed 18 gold rings, all of which were from the burial chest or the upper part of the wooden chamber. The top of these rings were made into rhombus shapes, and decorated with petal-shaped gold granules with small glass beads inserted in between. These rings, along with the gold bells unearthed with them, are known to be from the earliest era of Silla among all Silla gold-craft products.
