The green color is usually caused by iron and so is the observable bluish tint in this green stone. It is always something special when a tourmaline is blue, big and clear. It would be extremely high priced because sadly… there are none on the market. A good and inexpensive alternative is a green to blue tourmaline like this one as it suits several tastes and can be combined with different sets of stones (green, blue and mixed colors). This specifically is rare. This stone is clearer than emeralds of this size but contains inclusions which allow this tourmaline to be checked for naturalness. Green is not an unusual color for tourmalines, but the combination of size and the color green can only be found in rare big, clear rough tourmalines with the right amount of green in them. Cutting a tourmaline always means to maintain its best body color. If the rough tourmaline is too dark, then the tourmaline can easily be cut out of the rough piece. The rough piece is an elongated trigonal prism and allows a big-size tourmaline. If the color is not so intense then the cutter uses the stone´s pleochroism and cuts the table facet at the point of the rough stone which means that the stone has to be big in the beginning to maintain a large diameter. Green tourmalines tend to be either too light green or too dark green. Especially bigger tourmalines, of which only very few are found each year in an intense color, are suitable to show their inherent best color as the stone´s table will be bigger. Tourmalines grow elongated, so their diameter is growing slowly. This is the reason why big-sized tourmalines of a color which is neither too dark nor too light are very rare.

Green tourmalines tend to be either too light green or too dark green. But not this one! Especially bigger tourmalines, of which only very few are found each year in an intense color, are suitable to show their inherent best color as the stone´s table will be bigger. Tourmalines grow elongated, so their diameter is growing slowly. This is the reason why big-sized tourmalines of a color which is neither too dark nor too light are very rare. The green color is usually caused by iron, but unusually green tourmalines can exhibit a green caused by vanadium and chromium. This specifically is rare and this stone´s dark-green color is partially caused by vanadium as well. This stone is clearer than emeralds of this size but contains inclusions which allow this tourmaline to be checked for naturalness. Green is not an unusual color for tourmalines, but the combination of size and the color green can only be found in rare big, clear rough tourmalines with the right amount of green in them.

Cutting a tourmaline always means to maintain its best body color. This happened in this big-sized tourmaline because despite its size the color is still warm and intriguing. If the rough tourmaline is too dark, then the tourmaline can easily be cut out of the rough piece. The rough piece is an elongated trigonal prism and allows a big-size tourmaline. If the color is not so intense then the cutter uses the stone´s pleochroism and cuts the table facet at the point of the rough stone which means that the stone has to be big in the beginning to maintain a large diameter.
