Sometimes a simple setting is the best. The stone is natural citrine. It has a very shiny polish with crackles of citrine's delicious yellow.
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 solid sterling silver chain that is adjustable. You can wear it as long (up to 26 inches) or as short as you like.
