Aquamarine is mined in many countries across the world – Brazil, Zambia, Nigeria, Madagascar, Pakistan and Mozambique.


Aquamarine registers between a 7 – 8 on Mohs scale. (Unit of measurement used to test the hardness of gemstones.) Whereas, a diamond measures 10 on the scale, so aquamarine is a relatively hard gemstone and will withstand daily wear.



Aquamarine gemstones are often heat-treated for colour enhancement, but many are untreated. Heating at low temperatures will reduce unwanted green and yellowish tones. Darker shades of aquamarine are almost always heated, as well as lower quality stones in order to enhance the colour to be a favourable blue.
