I have had three replacements and each tarnished unfortunately. They discoloured, tarnished, became porous and turned my finger green. I was really disappointed as the ring is lovely & I wanted to give an opportunity for AL to rectify the manufacturing issue / change the material etc however it seems it hasn’t been addressed. I believe that is why the reviews are positive as the ring is initially beautiful when you receive the email to review but tarnishes very easily. I have had other jewellery from here which is lovely and I have had minimal issues with - nothing a replacement would not solve and which they have been brilliant at doing.
