Black Sterling is achieved by the oxidation of sterling silver. This blackened state will fade depending on skin type and sometimes quite quickly, the faded look can be considered an enhancement but we will be happy to help teach you how to re-oxidize your pieces if you prefer the pure black finish. Additionally, please note that Black Sterling tends to look darker in photograph then in person.
Super Ultra Acid Gold.
Brass substrate is electroplated with 18k gold and then submerged into a heavy acid bath. Once the initial deterioration occurs the surface is then burned to finalize the texturing. The resulting landscape is a natural occurrence. The concentration of the plating solution, air temperature and time in the acid bath all play integral roles in the final result. No two items are the same and these nuances / variations should be seen as a characteristic of the product.
