If you can think it up, chances are I can make it for you. First we start with the design. I work in Bronze, Silver and Gold.
Platinum is available in custom work with an extended lead time.
I would suggest you find a ruler and measure a piece that you enjoy wearing and judge for size. Three inches doesn't sound very large until it is cast in gold and hung around the neck for a few hours. I can create a one of a kind or make a mold for limited runs. This can come in handy when planning for a fund raiser or group emblem. All molds are kept here at the shop and copies are made on demand.
