Aside From Celtic Knots And Scotsgaelic, Is There A Gem Or Language Like Ogham(irish) To Make A Ring Scottish?

Kind of a strange question as I know Scottish ring = celtic knots or Scots-Gaelic... Just looking at any other options. Our background is Scottish and we're pretty artsy folk; we want to be really unique with our Scottish influence to our rings. I really love the Ogham alphabet, but understand it's primarily Irish based. So anything similar out there? Iconography? Any national gems or other touches that would be easy to add to a custom made ring? Thanks!!
