The gold from the Pactolus Valley contains platinum-iridium inclusions(65% Pt, 30% Ir, a little Os) analyzed by laser microprobe. These only occur in a few gold sources (Pactolus, Urals, Mandalay) and are used to characterize gold in a 5th century Achaemenian earring, a stamp seal, and some of the gold in the famous Bronze Age funerary hoard as coming from the Pactolus, The Achaemenian earring also contains 168 solder joints, inlay in carnelian, turquoise, and lapis lazuli, and cinnabar backing up the carnelian. Ur gold also has these inclusions. -- AATA
