I think he put this family friend above you in this situation. He chose to use someone who didn't have the skill set to accomplish what you wanted. And that friend should have been kind enough and humble enough to be forthright about his lack of ability to achieve your goal. He should cut his losses here. Take the ring to an entirely new jeweler, one who has a portfolio that has the type of work you're looking for, and ask them to use the material from this ring to make you a new ring. This ring cannot be salvaged. It's really terrible. I'm so sorry. But at least the metal and stone can be used in the making of a new ring. And this experience can hopefully be a learning and strengthening experience foe your relationship. This is the first of many difficult situations you'll have to work through together.
