According to GIA, 95% of sapphires have been treated in some form. Unheated means this sapphire has not had any treatment, including the common heat treatment, and therefore the colour and cleanliness is completely due to natural formation and survival of the gem over many thousand years.


When we source our sapphires we make sure they are of the finest quality and will be the highlight, in their own right, irrespective of the jewellery design. Each gemstone is cut to enhance its natural beauty, and in such a way that it may be set in the simplest solitaire engagement ring setting to stunning effect.
