I put items I like in my wish list so my husband and son can buy me gifts I prefer for holidays or birthdays. My birthstone is Opals and I love Tanzanite so this ring was something I really liked. For my October 2011 birthday I received this ring. The opal fell out the next day. It was returned for refund.  Giving it the benefit of doubt, my husband and son ordered the same ring again. The same day I received the second ring the opal fell out again. There is another review here for this ring complaining about losing a stone. I'll have to say, "Order at your own risk." It appears the prongs are too short to hold the stone in tight. This is not an expensive item but obviously it shouldn't just fall apart the first time worn.
We will be returning this ring tomorrow. We will not be ordering another ring from the company that made this one.
