I'm, with Danielle! The Santa Maria 'looks' fake as opposed to natural..
I think that the reason it looks fake is that it is not what you are accustomed to seeing. I think many people even in the trade have never seen one in person. They are extremely rare, and expensive.
But I can tell you from personal experience cutting some, they are magnificent. Visit the Idar tent in Tucson if you ever want to see some. They usually have some on display.
Don't give up on getting to cut a big piece of the lighter tones. They are commonly available and not high priced.
If this is the case, then, how come there are a lot of deep blue aquamarine stones in china...?I too prefer the lighter colored aquamarine stones, because the deep/dark blue ones in china look so fake. I wonder now, what kinds of things do those chinese people do to the aquamarine stones to make them look so blue.
Money attracts high quality stones. There are a lot of people on China who can buy top color Aqua. Your question is more about economics than it is about aqua color.
The fact is that dark aqua is more rare and valuable than light color. Your personal taste not withstanding.

I know the darker blue ones are more valuable...its just that there are a lot of them, and they are not that expensive, so I suspect that they might have done something to the aqua stones to make them turn dark blue....
You can irradiate beryl to get darker blues but they fade. You can heat greens to get a purer deeper blue but it doesn't make them much deeper. Aside from that you're left with simulants. In theory you could get a synthetic but I don't think there's any commercial synthetic aquamarine.

So it is not possible to turn light blue aquamarine stones into "devilish blue" colored aquamarine stones?

tastyGem,
Can you post a link to one of the dark inexpensive Aquamarines please?
There are a lot dark blue aquamarines like these in China. Chinese sellers even make up a name for them; they call them "devilish blue" aquamarines...
Is this parcel of cabs your inventory? I am curious as to the cloud like inclusions in the smaller lower stone. Looks like some formations of stalagmites or similar.

Not really. Dark blue maxixe-type can be generated via irradiation, but the color is different from aquamarine, strong pleochroic and not light stable. If you're concerned it may be maxixe you can check with a dichroscope or even just a computer monitor. Maxixe has its strongest color down the c axis with almost colorless A axes, while aquamarine is actually weaker in color down the C.
