Limestone block with perforations and molds on all four sides, used for polishing and finishing earspools. The holes vary in size, allowing for the polishing of circular jade earspools and possibly obsidian. This process involved introducing sand and chert powder into the perforations, after which the earspools were rotated against the abrasive material to achieve a smooth finish.
