KA:Black Sterling. Black Sterling is acheived by the oxidization of sterling silver. This blackened state will fade or scratch off over time but we will be happy to help teach you how to re-oxidize your pieces if you are interested (it is a very easy process). Additionally, please note that Black Sterling tends to look darker in photograph than in person.
JET:Jet. Fossilized coal (Alternate name: Lignite). The jet form is completely hand carved.
