Lubird...leave the aquamarine in there. It is so much prettier. Why not make the green amythest into a necklace? I just don't love trillions in rings unless they are small side stones. Plus if you leave the ring as is it will have sentimental value.
...I LOATHE purple too...but my sons birthstone is also amythest and I wanted, for whatever reason, to get a ring or something with both my childrens birthstones....My daughter is a DIAMOND...I planned that one well and have more then enough for her...but he has just the worst stone. (I am a garnet, which is not MUCH better...but red trumps purple anyday!) Anyway, in my searching I came across the rose de france amythest wich is sooo much better and if I can find one in a setting I like I would love to get that.
The green amythest is pretty, but doesn't sparkle too much at all.....I was looking at some at helzburg and even under the jewlers light there was nothing going on. I was hoping I could find one I like as it is a necer color then the purple for sure.
