There is an image going around on Reddit and Facebook with the following caption: A gold necklace discovered in Hepu Han Dynasty cemetery. 206 BCE-220 CE, now housed at the Hepu Han Dynasty Cultural Museum in China.
I have not yet found an actual cite that confirms this. A dig may have taken place in 2022. The style of the dodecahedral beads and the early end of the alleged 206 BCE to 220 CE date range would be consistent with the gold beads discussed upthread which were found at archaeological sites in Thailand and Vietnam.
The museum describes the beads as “olive and flower balls”.
