Jewels of Nature

A New High Jewelry Experience

"I was inspired by animals and all the diverse colors you find in both nature and these opals. The animals were perfect as my muse. Each piece, a one of a kind, shows off the iridescent colors in these beautiful opals but also takes on the characteristics of the animal."

- Monica Rich Kosann

“The art of creating is always a desire to give life to something that is an object. When you start to put gemstones into a design, they take on a life of their own.”
