Tanzanite is a rich in colour, elegant gemstone prized for its exquisite ultramarine blue-violet colour. This rare gemstone mined at the foot of Mount Kilimanjaro is a popular alternative to the blue sapphire. The combination of blue and violet with the vibrant sparkle allows Tanzanite to claim its place as a mystical gemstone of modern times. If set in a ring this gemstone requires special care as it is not as durable as other gemstones.
