Jewels of Nature

A New High Jewelry Experience

"I was inspired by animals and the colors you find in nature and these opals. The animals were my perfect muse. Each piece, a one of a kind, shows the iridescence in these beautiful opals but takes on the characteristics of each animal."

- Monica Rich Kosann

Colorful Gems An exclusive collection of designs, created with the finest quality gemstones.

“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.”

 

- Monica Rich Kosann

The Vintage Diamond Vintage Diamonds in modern heirlooms

“I love to imagine all the different places and historical moments these diamonds might have been. These pieces all use vintage diamonds to give you a piece of the past, but with a new design.”
