Jewelry with a Scottish theme became very popular when Queen Victoria and Prince Albert acquired the Balmoral Castle in Scotland (1852).
The Victorian pins were set with agates, amethysts and citrines and often portrayed the thistle which is Scotland's national emblem.
You will also find the Scottish theme in Victorian Revival pieces from the 1930's ,1950's etc.
The above brooches and pins are Victorian Revival pieces from the company Miracle which started in 1946.
