gold

金 is a pictograph depicting the smelting process of an axe head. In ancient times, 金 could refer to any hard, lustrous, malleable substance with electrical and thermal conductivity. Nowadays, 金 specifically denotes the particularly rare substance among these, i.e., gold. Notably, the two dots in 金 represent liquid, symbolizing the process of metal being melted at high temperatures and then cooled into a solid form.
