Thank, Jan, for the aditional information. Certainly, southeast Asia at the time had more gold than most places. It was known in India as Suvannabhumi or Suvarnadvipa, "the land of gold." When the Roman Empire was running critically short of gold in the second half of the first century AD, envoys were reported to have been sent to Oc-Eo at the southeastern tip of Asia to procure more. And gold was one of the main reasons why China in the Han dynasty invaded Vietnam.
But however much gold there may have been, the repairs show, as you say, how valued the jade or jade-like articles were. I have other bangles repaired with bronze and iron, but the gold looks by far the best against the green.
