Aquamarine

Found in green-blue to blue colour variations, aquamarine crystals get the blue tone due to the presence of iron within the crystal. They are comparatively large and well-formed and the depth of sea blue colour is most intense in large specimens while the colour in smaller stones is comparatively lighter. Unlike other coloured gemstones, aquamarine’s value comes primarily from its tone rather than the hue and saturation and stones with darker tone are highly-priced and sought after.

Often found completely flawless, aquamarine has been found in Rathnapura, Rakwana, Morawaka, Hatton, Nawalapitiya, Galle, Matara, Tissamaharama and Lunugamwehera in Sri Lanka.
