Description: Absolutely genuine Ruby in Zoisite large 14mm bead bracelet This is true Ruby Zoisite not like the many Green and Red Fushite sold as Zoisite on ebay from the Chinese sellers or the cheaper Indonesian Zoisite The Indonesian Ruby in Zoisite, is mostly Zoisite from the green host rock, not much natural ruby Ruby-zoisite was first discovered in 1954 in the Longido mining district of Tanzania. To this day, it is still the world's only source for ruby-in-zoisite. As you can see from the last 4 photo's True Ruby in Zoisite costs a small fortune Bracelet is Elastercised so will fit all sizes Photographed on my 17cm wrist Beautifully Highly polished Weigh approx 55 grams, approx 270 carat Fabulous condition. Superb ruby crystal, the red-pink gem variety of the mineral species corundum, in green zoisite matrix. The ruby crystal has exceptionally rich colour and runs completely through the matrix. Longido, Arusha, Tanzania Ruby is a gemstone version of the mineral Corundum, a simple aluminum oxide mineral. Corundum is rare on earth as it requires there to be lots of aluminum and a more limited amount of the most common component in the Earths crust; silica. On occasion, such as in metamorphic rocks of Tanzania, high-aluminum sediments have been heated enough to cause corundum to grow. This piece of Corundum is showing you important details of its structure there are beautiful bands of colour Aluminum doesnt typically give minerals colour as the electrons in that structure dont absorb light in the visible range. For rubies to get their colour, they have to have another component present with electrons that can absorb visible light. In the case of ruby, it is chromium; chromium has the same charge as aluminum and a similar atomic radius, so some of it can substitute into the ruby structure in place of the aluminum. The outer d-electrons in transition metals like chromium can commonly jump from one d-orbital to another using the energy available in visible light, causing them to absorb visible light and making them the pigments for crystals like this. The layering in this ruby is likely reflecting how much chromium was available at every stage in ru
