Volcano ring | Eva Martin Jewelry. Platinum, 18k Yellow gold, Sapphires. Rob and Rachel had a wonderful first date, but they met just as Rachel was about to fly to the UK for months away. However, as Rob writes.... "the Icelandic Volcano errupted, planes were unable to fly and her trip was canceled. We saw each other many times during the time she would have been traveling; in a very real way that volcano made the relationship happen."
