During a long hike this couple became thirsty and fed each other blueberries which they found high up in a Scottish mountain and realised that they better get married. The blueberry is depicted with a sapphire, the centre of which looks like a little crown in which I have mounted a diamond. The shank of the ring meanders in a depiction of the path they trod.  Incidentally she received this ring at Heathrow on her way out to compete in the cycling event in the Rio Olympics.
