Agree on the strand. It's fake. The color is super strange and you can see the layer peeling off.
Did you check what the broche is made of? Is it real gold or not? Even if the two pearls are Akoya (saltwater pearls) the value of the gold would be much higher than the pearls. If the broche is not made from solid gold, the pearls could easily be imitation. If you wash them gently, you can try to gently rub one of the pearls against your teeth. Genuine pearls will slightly gritty and imitation pearls will feel smoother. You can also try with a loupe. Enlarged, real pearls will look smooth and fake pearls less smooth.
