Color: AGA: pure acid gold. The pure silver substrate is electroplated with 18k gold and then immersed in acid to form a delicately damaged surface. The concentration of the plating solution, the air temperature and time in the acid bath all play an indispensable role in the final result, and there is a delicate balance. No two items are the same, these nuances/differences should be regarded as characteristics of the product. Material: gold-plated sterling silver Family: New Moon Series: Series 15 Tags: Aircraft
