Yes, most of the US engagement rings are diamonds. Usually, it is hard to find a decent engagement ring of quality with another stone. Plus, not everyone will recognize it as an engagement ring either. I went to 25 jewelry stores shopping for an engagement ring about 2 years ago. I only saw one other stone and that was a sapphire. But it was used as an accompanying stone with a diamond. I think after all these years it is a bit of Princess Diana's influence yet. Many celebs are doing colored stones, but it hasn't trickeled down yet. Maybe in the future.
I wanted my engagement ring to be really unique. I also wanted 3 stones. But in the end I bought a ring that looked antique with hand engraving and scroll work around the band and a diamond in the center with smaller diamonds down the side. It is platinum and yellow gold. I really like it b/c it was very unique. Many people were suprised it was my engagement ring. But that is why I love it. I don't think that you can really find a decent engagement ring that isn't a diamond here. Maybe in really large cities or on the coast but not everyday. However, maybe it will change. And I suppose you can always get one custom made.
Does anyone have a close up of Mabel's and Laurentian's of the Netherlands engagement rings? We've seen them from a distance in official potraits but nothing close up to see the details. Anyone have one??
