I was unhappy with my purchase at first. A stirling silver ring presented to my fiancé to symbolize my eternal faith in our love and unity. An hour after wearing the ring (which fit perfectly due to the ring sizing chart that this company provides????) it started turning his finger greenish/black. I'm not all knowing, but have NEVER seen stirling silver do this to anyone. I thought I had been taken advantage of. However, after emailing myirishjeweler.com and doing some research online, I found out that due to certain PH levels in the body silver can discolor the skin. He's never worn silver rings before so this was new to us. Fortunately, the discoloration didn't last long and my honey is wearing his ring proudly and he loves it!!!!
