Unusual 9ct Rose Gold Long Chain 29 inches 13g vintage modernist textured links

Unusual chain - my best description of each link would be'squared oval, flat links, beaten-effect, each link about 5mm long' but please look at the photos or ask if you need further photos. The gold colour has been listed as'rose gold' because it's not yellow or white. But it's a pale rose gold, not like the modern coppery rose gold - more like antique rose gold but this chain is definitely not antique. It only really looks rose when placed next to a yellow gold piece!

9k on the jump ring. 9k on one side of the tag. 9.375, import mark and indistict letters on the other side of the tag. 9.375 on each end ring of the chain.

13g weight, length approx 29 inches.
