Round Sterling Silver Victorian earrings

I always was under the assumption that these earrings were a typical example of "classic" silver jewelry from the Victorian era. And as you stand still yet again for surprises because I wanted to post them here on CW I had a good look at the text that's on both:
Erin go Bragh
This is an Irish pronunciation. It is the English corruption of Éireann go Brách and means "Ireland Forever", or as it is usually translated, Ireland forever. This statement is strongly associated with the Irish Republican movement.
Furthermore I looked the image and there is a harp in it. And here is the history of the harp for Ireland :
The coat of arms of Ireland is blazoned as Azure a harp Or, stringed Argent (a gold harp with silver strings on a blue background). These arms have long been Ireland's heraldic emblem. References to them as being the arms of the king of Ireland can be found as early as the 13th century. These arms were adopted by Henry VIII of England when he ended the period of Lordship of Ireland and declared Ireland to be a kingdom again in 1541. When the crowns of England, Scotland and Ireland were united in 1706, they were integrated into the unified royal coat of arms of kingdoms of England, Scotland and Ireland. The harp was adopted as the emblem of the Irish Free State when it separated from the United Kingdom in 1922. They were registered as the arms of Ireland with the Chief Herald of Ireland on 9 November 1945.[2]
The depiction of the harp has changed over time. In the 17th century, during the period of the Kingdom of Ireland, the pillar of the harp began to be depicted as a bare-breasted woman. When the arms were restored as the arms of the independent Irish state in 1922, a late-medieval Gaelic harp (a cláirseach), the Trinity College Harp, was used as a model. Traditionally, the shade of blue used in the arms is known as St. Patrick's blue.
