Carole Lombard's Star Sapphire Brooch | Maker's Bench
The following post will show you How It’s Made
Shown above is a detailed image of the glass "gem" and the bronze casting. You can clearly see the Pave setting.
It is best to finish the castings before soldering them together. This insures that all the parts have the best polish.
The next step was to solder the baguette gems mounting to the main brooch. Once the pieces were soldered and finished we prepped them for plating. You cannot plate metal if the stones are set. Once the brooch was plated we then could start setting the gems.
Our assembled casting was Rhodium plated to simulate platinum. We agreed that most likely the original brooch was made in platinum. Adding the Swarovski gemstones to the new brooch went quickly. The next step was to channel set the crystal baguettes.
We had tried several methods from engraving the star on the backplate in the brooch to painting the star effect behind the glass gem. We ended up painting a star on a thin piece of film that was inserted behind the glass "gem" and the backplate.

Along with Larry McQueen, the owner of The Collection of Motion Picture Costume Design we delivered this "star sapphire and diamond" brooch to the Academy of Motion Picture Arts and Sciences in Los Angeles.
