The Australian Crystal Opal & Diamond Flower
“What better way to celebrate the beauty of florals than with Australian Crystal Opals and Diamonds? When I saw the shape of these vibrant and iridescent gemstones, the petals of a flower immediately came to mind, creating a uniquely special design.”
- 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.”
