Sumatra Minangkabau earring. Gold, diamond center

4 cm diameter, Thomas Murray collection. 19th century or earlier. PD for age. More info for the Minangkabau culture in west-central Sumatra: en.wikipedia.org/wiki/Minangkabau_culture

 

I'm not sure what the red tint is. But fairly common in that collection. If anyone knows, please post!
