My partner and I purchased two rings and both have turned our fingers green as well as now I put the ring on my necklace as it has such special sentimental value as it has our initials and our anniversary, but it has now turned brown even though it was on my necklace with other pendants that are sterling silver. Very upset as we spent over $150 for both these rings that we now can’t wear as it will make our fingers green and I can’t wear it on my necklace as it looks very dirty. DON’T WASTE YOUR MONEY!!
