Tanzanite is one of my all-time favourite stones. It's violet-blue radiance illuminates in such a way as to leave you mesmerised and perhaps, intrigued. Although tanzanite is one of the most rarest coloured stones to be found and commercially mined (i.e. in Tanzania), it is also one of the most expensive gemstones. However, that is not to say that all forms of the luscious purple stone cannot be acquired and appreciated. As demonstrated by Elisa Werbler's collection "The Birthstones," it is possible to have that little piece of perfection as a possession. Tiffany & Co., the company that named the relatively soft stone, has also released a line, designed by the talented Elsa Peretti, to give the budget-conscious clients an introduction to tanzanite, named "Color by the Yard". It is now something to be desired, yet attainable.
