The tanzanite’s rarity is what makes it so appealing: it occurs naturally only in the East African country of Tanzania. It is a beautiful stone known for its deep blue colour. However, the variety of hues it can take (ranging from ultramarine purple-blue to light violet-blue) makes this gem especially unique.
Faceted stones are often used to make fine jewellery, and the crystal clarity of these gems is especially striking when set in platinum engagement rings. This effect is particularly evident with larger gemstones over 10 carats.
Tanzanite, the December birthstone, is a breathtakingly beautiful gem. In different lights it sparkles from purple to violet-blue and makes an excellent birthday gift for those who enjoy jewellery — it's also perfect for brightening up darker months.
