What color is it?: Well, in its better colors its a lot darker than the one I have shown above. Unfortunately, most people see the very light blue color of aquamarine. But in its finest color aquamarine will be a rather dark blue, rivaling a nice medium blue sapphire. But they are rare and expensive.
What is the story behind this gemstone?: For many years a favorite of many consumers. It lost some of its appeal when the much cheaper treated blue topaz come onto the market. But a nice, medium dark blue aquamarine is a very, very fine gift for any occasion.
Can I wear it everyday?: Yes. Although this is a sister stone to an emerald (both beryls) aquamarine does not have the brittleness that is sometimes associated with emerald.
Is it expensive?: Aquamarines in the very light blue color as seen in the photo above will be priced comparable to a green tourmaline. But the darker blue colors will cost much more in the range of a fine chrysoberyl.
Is it a birthstone?: March
What do I need to know before going shopping?: You need to stay with a professional independent jeweler who knows his or her colored gemstones. Far too many blue topaz have been sold as aquamarines by jewelers who did not know how to properly identify a nice aquamarine. So stay with a well established jeweler who deals in a lot of colored gemstones.
