Full-Cataloguing
Weighing in at 31.19 carats, unheated Burmese sapphires of this size and quality are exceedingly rare. Modern Burmese mines yield very few sapphires and very few of gem-quality over ten carats make their way to the present day market. Burma accounts for only 10% of the world’s total rubies and sapphires, and less than 1% stones of these are gem quality. The present sapphire combines an excellent combination of significant size, crisp colour saturation, high clarity and is a pleasing step-cut shape. It bears the rich brilliance and colour of a sapphire that is unmistakably Burmese.
