What is a good engagement stone other than a diamond or a birthstone?

Garnets are traditional engagements stones in England and Europe; the traditioin dates back centuries and has to do with the deep, red color of the stone, though I can’t remember specifically what it represents. My brother gave his wife an engagement ring with a garnet that they had found while gem-hunting in the mountains. She gets comlements on it constantly.

I would like to suggest a green stone, that is harder and tougher than emerald and that is green corundum, which is properly called green sapphire. If you could get your hands on a green star sapphire you would have a wonderful and unusual gem!

Or, what about the wonderful world of tourmalines. I have a rare green Maine tourmaline that looks so much like emerald that it is often mistaken for it. Please notice the emerald cut one on the site below:

Demantoid garnet is another rare but wonderfully colored green garnet that has such a beautiful look to it. It isn’t as hard or tough as the others but is so lovely.
