Aquamarine Gemstone for Sale Value, Price, and Jewellery Information
Aquamarine is one of those stones that invokes either a love or hate relationship amongst its various suitors. The stone’s name originally comes from the Latin “aqua marinus” largely translating to the water of the sea. The gemstone is typically categorized by its shiny blue to blue-green colour and ties in with a general sense of folklore around mariners and the ocean. Aqua was also kept by superstitious sailors for its properties of fearlessness and protection from peril. So THAT sounds like more than a good enough reason to buy and keep one in your collection!

This gemstone typically gets most of its colour from traces of iron and this is what gives it the distinctive blue-green ocean colouring. Most Aqua’s are now heated to remove the green component of the colour and to leave the light blue ocean tones. Heating is normally the treatment of choice and is now so common as to be undetectable. So do not be overly concerned by heat treating. The gemstones are typically not any darker than swiss blue topaz and if they are it’s highly likely to have a treated Aquamarine on your hands. In fact, if the stone is darker than topaz then you have what is known as a Maxixe Aqua and this is a stone that has been irradiated. The colour isn’t typically stable so I would caution buying any of these treated stones.
One of the major characteristics of Aquamarine is the specific type of inclusions that it has. The gemstone is characterised as having long hollow tubes which are normally view able under a microscope and if the stone is cut in the right way can actually form a cats eye. This is highly distinctive and if you see long hollow tubes under magnification then you are more than likely looking at a stone of the Beryl family. Note that cat’s eyes and Star Aqua’s typically command a much higher price than the average stone.
Potential Treatments and Enhancements
As already mentioned, most of these gemstones are now heated to remove the green colouring. This isn’t something you need to be overly concerned about and is a stable treatment. However, any form of irradiation to make the stone darker is a big no no and simply wont last for very long if you were to buy one. So avoid all Maxixe Aqua Marine specimens. The easiest way to spot a Maxixe is the fact that they have no pleochroism (colour change or multiple colours when you rotate the stones axis).
That’s typically the majority of Aqua treatments that you will face but always practice with a loop as you never know when you might strike something new or find a surface coating or diffusion or indeed a simulant when you are looking for an aquamarine gemstone for sale !
