How about two gemstones for the price of one? Ruby In Zoisite is exactly what you would imagine – Rubies encased by Zoisite. With such a unique and pretty combination of colours, this gemstone truly is a gift from nature! There are lots of other gemstone duos that we will feature in our Gem Of The Week series, but we doubt there is another as stunning as this one.


Ruby In Zoisite, also known as Anyolite, is a powerful combination of two minerals! The alternative name of Anyolite is derived from the Masai word for 'green' (anyoli). Other name variations include just “Ruby Zoisite” and "Tanganyika Artstone". Depending on its primary constituents, it can vary in colour, pattern, and hardness. Zoisite provides the vivid green colour while Ruby inclusions give it pink and red highlights. 


India is the biggest producer of this lovely combination gemstone. It is also found in Tanzania, Kenya and Zambia.


Ruby In Zoisite was first discovered near the foot of Mount Kilimanjaro, Tanzania in 1949. Tom Blevins though he had discovered one of the largest Ruby deposits in the world, but soon realised the opaque rubies were contained within a green matrix of Zoisite. In 2010 a 2Kg ‘Ruby’ known as the “Gem of Tanzania”, owned by the now defunct Wrekin Construction Co in Shropshire, was fraudulently valued at £11 million to prop up the company’s balance sheet. It turned out to be a specimen of Ruby In Zoisite that eventually sold for £8000!
