From the Heart

The Australian Black Opal & Diamond Heart

“Surrounded in yellow gold, with white gold vines and protective diamond thorns wrapping around the heart, this piece implies how challenging it is to guard our hearts at times, especially if we live loving!”

- 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
