Aquamarine Help

Can someone please help me with this discussion? I work for a crystal site and they want to list
Aquamarine as two separate crystals - Blue Aquamarine and Green Aquamarine. I have told them
this is wrong; that there is no "Green Aquamarine" per se, but they say otherwise. Can someone help?
Thanks so much!

Aquamarine is the varietal name usually used for blue beryl. As it is not a formal mineral name, it does not have a rigid definition. In practice, however, it's use is usually taken to mean the beryl is some shade of blue. Green beryl, if known to contain either chromium or vanadium as the coloring agent (chromophore) is called emerald. Green beryl colored by other agents is simply referred to as green beryl. Not the most catchy name for marketing purposes, but I would avoid calling it green aquamarine. That rather reminds me of seeing someone at Tucson a number of years back trying to market morganite as "pink emerald."

Like sea-water (from where the name comes) aquamarine can be blue, bluish-green or greenish-blue;; if it is green, to be called an aquamarine it should have a bluish shade, cannot be plain green (otherwise it would rather be called green beryl); the bluish-green specimens, as gem rough, are much less valuable than the blue ones, so it is always attempted to heat treat them to change the color to blue, what may happen on most cases but not always.

Sonia,
If the site you are working for is run by metaphysical types, I fear you are fighting a loosing battle. The metaphysical types will make up a name at the drop of a hat as well as a whole host of properties that have no basis in reality other than what a few individuals happen to feel about it. We try to follow the nomenclature of the IMA (International Mineralogical Association) which is run by some of the most knowledgeable mineralogists in the world, but their nomenclature is bases on the scientific method where everything must be able to be measured and repeatable, in a scientific sense. Unless the people that run you site buy into that paradigm, you are fighting a loosing battle.
