Green and yellow tourmalines are the most common of all color variants and are therefore less valuable than blue and red ones. Green tourmalines are mostly produced in Brazil, Tanzania and Namibia, while yellow ones are found in Sri Lanka.

Among all the Brazilian mining sites, Paraiba state produces a tourmaline with a special green-blue tone. It is very expensive and scarce and in extremely large demands. It is therefore named Paraiba Tourmaline.
