Burnished Pendant on Black Jet Beads Necklace

Burnished silver-coloured pendant on black jet beads necklace In the centre of the pendant is a stone, probably a natural Agate, the kind of stone that is found on many Canadian beaches, particularly in Nova Scotia and Newfoundland and Labrador, and lovingly polished by a jeweller On the pendant itself, there should be 7 tiny stones at the top of and surrounding the large grey centre-stone, but 2 of these tiny stones are missing. I have priced it accordingly Last photo shows the inside of the oval pendant Comes from smoke-free and pet-free home
