Turquoise is an opaque, blue-to-green mineral that is a hydrous phosphate of copper and aluminium. The word turquoise is derived from an Old French word for "Turkish", because the mineral was first brought to Europe from Turkey, from the mines in historical Khorasan Province of Iran.

With this info in mind perhaps the combo would be that of METAL & WATER or METAL & EARTH
