I've been thinking that if I were to be engaged, I would want flat rings, none of that pointy shit.
I don't want big, gaudy diamonds or gold
I don't want some huge rock on my finger weighing me down with responsibility and expectations.
I want simplicity in my ring, a flat, plain ring with maybe a celtic knot engraved and a single stone of some kind. Just not a diamond. I would want an emerald and a silver band.
For my wedding ring I would want there to be some slip to it where it would fit into the ring of my spouse to be. That would make it such that our two rings completed each other to compliment our vow to one another.
