We are pleased to offer for sale this impressive piece of ethically-sourced, rough aquamarine from Sri Lanka (see pictures further down this page).
This stone was extracted from our own small-scale, artisanal mine in the Kuruwita region of Sri Lanka on the 24th of August, 2014.
Due to the nature of the deposits in Sri Lanka, it is unusual to find such large pieces of rough stone intact. It is guaranteed 100% natural and untreated in any way.
The stone has some large, clean parts that appear to be gem quality and the colour varies from a medium blue to a pale blue on different sides of the crystal. It appears that a few large stones (100ct and above) could be cut from this crystal, as well as one or two large cabochon stones and a number of smaller stones, both faceted and cabochon.

Aquamarine’s name comes from the Latin phrase meaning “water of the sea”, based on its colours which can range from shades of sea-green to blue (sky blue to dark blue).
It is a member of the beryl family which also contains emerald, morganite, golden beryl, heliodor and the very rare red beryl.
With a hardness of 7.5 on the Moh’s scale, aquamarine is robust and resistant to scratching, making it ideal for all kinds of jewellery.
