AG:Acid Gold. Brass substrate is electroplated with 18k gold and then dipped into acid to create the subtly destroyed surface. The concentration of the plating solution, air temperature and time in the acid bath all play integral roles in the final result and exist in a delicate balance. No two items are the same and these nuances / variations should be seen as a characteristic of the product.
DIA:Diamond Slice. The stones used in this item are slivers of diamond material that are removed from a larger chunk of diamond as they are attempting to get to the perfect diamond in the center. Each stone fragment and shape are absolutely unique.
