Susan Hayward’s Star Brooch | Designing and Carving the Wax Models

Before we can start making the waxes we need to have the gems in hand.

Since finding a real emerald cabochon within our budget was not possible. We were delighted to have found a vintage glass cabochon that looked like it was made for our project.

Here is the green cabochon placed on a polished background plate of sterling silver. We did this to determine the best way to present the stone, so it would maintain the rich color. Should we have a plate behind the stone or not?
