Hi All, new to this forum so apologies if I’m posting in the wrong place. I was recently doing some ground work for a family member at the Rhiw goch inn which is in wales in a town call Bronaber and I came across this pendant. A friend of mine said it was silver but I’m unsure can anyone shed any light on this item for me as I’m very curious about it as it seem different from the other types of pendants in this style. I’m unsure if I should clean it as a friend said it can lose its value but I have no clue any help would be much appreciated. Thanks
