Here is a pretty little ring that contains an alluring greenish color cabuchon that was mined at the Royston mine in Nevada. You'll often hear people say "Nevada green" turquoise and it is often found in Nevada, however it can be found in the King's Manassa mine in Colorado or a myriad of other mines in Arizona. This ring is a size 4 1/4, it carries 3 carats of turquoise and measures 14/16 in. long by 1/2 in. wide.
