Antique bird brooch with tigers eye quartz and old mine cut diamond diamonds

This brooch is the one that gives me all the feels. I'm not sure if it's because I'm drawn to animal brooches, or if it's the intricacies that are exciting me, but it is truly beautiful with a slew of different materials and probably some hidden meaning that I'm not aware of. This is set in 18 karat yellow gold and silver, the three birds are carrying a tigers eye quartz and are sitting on wires. They almost look like musical notes. The pearls that are on each side are likely cultured and have beautiful luster. The rose cut diamonds are all intact and are in good condition, the pink eyes are likely sapphires, though I can't get a read on them so I'm not 100% sure. It measures 2 inches long by 1 inch high, it weighs 10.27 g
