This swimming-pool blue Tourmaline of 20.85 carats shows a distinct turquoise-blue color which is very typical and worldwide recognized as being a Paraiba tourmaline. Usually tourmalines are cut where they show their most intense color, which is parallel to the c-axis. To cut a large table a big stone is necessary and to take as much stone as possible from a good rough a triangle shape is worthwhile due to the trigonal crystal system of tourmaline. The weight of 87.52 cts. is very rare for this color because most copper and manganese colored purple or bluish tourmalines are found in rare areas in Brazil, Mozambique and Nigeria. Rarely from Africa, Mozambique, come big purple tourmalines and if the chemistry fits they are heated to yield the swimming-pool blue Paraiba tourmalines. The combination of transparency, size and intensity of color makes this Paraiba Tourmaline an interesting investment. A color like this with these inclusions and chemistry cannot be synthesized nor obtained via irradiation. Therefore not only the certificate by DSEF and SSEF stands for naturalness and rarity of the stone but also visible inclusions (so called „trichites“) are a natural remnant visible under the microscope. Any other stone imitating this like naturalness apatites will never gain the myth of a “Paraiba Tourmaline”.
