Pearl Locket I Recently Received An Antique Gift And Was Just Curious To Find Out How Much It Would Be Worth Today?

I recently received an antique gift and was just curious to find out how much it would be worth today? - pearl locket

This is a brooch with a silver hand-drawn bow and the bow is suspended a gold medallion with the face covered with mother of pearl. It is really beautiful and in good shape. If I have two photos in it, a woman and a man in the uniform of the Second World War, and it is very old.
Just curious, if they have a value that was like a gift and I will always treasure was.
