This is lovely. I'm interested how it can signify two lives coming together to make something beautiful and complete.
The story is told that in ancient times a Turkish Nobleman was so in love with his wife that he wanted to be sure she was faithful to him while he was away. He asked his jeweler to make a puzzle ring for his wife that would fall apart when removed, and he would not tell her the solution.
This is a ring I made, but there is not mentioned anywhere. Its available here: https://www.etsy.com/listing/43129984/10pt-diamond-puzzle-ring-in-14kt-gold?ga_search_query=diamond
