* Ceylon sapphires (mined only in Sri Lanka) are known for their unique colour, ranging from very pale blue to vibrant almost electric blue. The colours noted within Ceylon sapphires occur naturally and do not tend to be heat treated, the most sought after known as the cornflower blue.

Images do not always reflect the true colour and brilliance of gemstones and diamonds. The video however provides a truer representation of the actual colour and showcases each stone.
