I am onto my second set of rings. When I was on the way to hospital for birth of child no 1, I took my engagement ring off and put it away safely, and wore only my wedding ring. You guessed it, engagement ring never to be seen again, though it was certainly not one of the rocks that are around today. If you looked carefully you would see the diamonds!
Anyway, fast forward 11 years to 1990 and Mr L_t_L surprised me with a new set of three rings when I finished all the chemo and radio treatments. He had chosen them and paid them off ready to give me when it was all over. When he gave me the box I thought it was a pair of earrings! I dropped a diamond from the eternity ring a while back so it is waiting for me to get around to having it repaired.
