Vintage Goldtone and Blue Opal Floral Leaf Brooch

This exquisite brooch features a delicate leaf design in goldtone, adorned with striking blue opal doublet stones. Perfect for adding a touch of elegance to any outfit. From my research these look like composite doublet Australian opals but I am not sure so offering at a great price. See last photos for comparison of similar brooches. Measurement: 1.5 inches long, 1/2 inch at widest point. From a smokefree pet friendly home. I use recycled shipping packages for the environment.
