This stone looks like a little northwoods scene. It's real; painted by nature. The stone is actually called Picasso Marble, so I guess it goes to reason that it would look like a little picture.
I set the stone using sterling and fine silver and accented it with jeweler's brass, also called red brass. It has a warm gold-like color without the price of gold and gains a lovely patina over time.
I have the pendant suspended on a 16" German made natural rubber cord with sterling end clasp.
