Is this an aquamarine diamond?
I have this ring that I have had for about 2 years and I have been told that its only worth about $200 by a friend who works in a jewelry store but has never seen the ring. It looks almost identical to this ring in this photo on this website but I am not sure it is the same kind. Let me know if you ever heard of this kind of stone. Thanks

So far as I know, there is no such thing as an aquamarine diamond. I think there’s a misunderstanding – there is a gemstone called “aquamarine” and then of course there are diamonds. The ring pictured has an aquamarine center stone with accent diamonds. You oughta get that ring appraised, cause all you or I can do is guess at its value! 
Good luck.
