This fine silver, pierced brooch has 5 pearshaped turquoise stones surrounding a 7-8 carat Moonstone. The outer circle has been hammered for a sparkling effect. The front photo doesn't show the subtle blue reflection that you will enjoy in person. It is finished with silver balls of solid sterling silver.
The brooch is marked sterling which happened before I realized I had picked up a fine silver disk. Being made of fine silver means that it is softer metal and that it will not tarnish, it will always be bright.
This brooch is 1 3/4 inches (45mm) in diameter. Here is one photo taken on a grid of 1 inch squares.
