So my boyfriend and I just got engaged and he thought he was buying a very high end expensive ring. The truth to that is that it was an expensive ring. He paid $5200.00 for a 3 1/2 total karet diamond ring thats made of 14 karet white gold. The ring is beautiful but the next day after I was wearing it, it was already turning my finger green!!! So I was looking on the internet to see if a 14 karet gold could turn anyones finger green and I wanted to go to Landau website, so when I googled them I came across other people complaining about their jewlery. I just thought I would also put in my experience too. DON'T BUY FROM THEM!!
