Another query for the knowledgable - I’ve just acquired this cuff (again, I buy cos I like the colour and font tend to think of age etc) but there seems to be a bit of silver along the edge (and pyrite in the middle?). I’m assuming this is not naturally occurring but haven’t seen it before?
Thank you for helping - I’m learning all the time just by reading all the posts on here and finding it invaluable xx
Like Christibo indicated it can be tricky. It could also be filler to fix a crack. The center just looks like host rock? don’t see anything that looks metal. I have seen heat change a stone color, especially when someone is buffing a piece. It is interesting that you see those dark spots by this silver/pyrite/filler, from the heat of fixing and then buffing to get it smooth. The stone is a very nice blue.
Thanks - it definitely looks like filler when you look at the top side of the stone so that makes sense just not seen a silver coloured filler. The middle is host stone - under a loupe it has a coppery glint but I’m guessing that’s just from the stone.
