Almost every color of tourmaline can be found in Brazil, especially in [[Minas Gerais]] and [[Bahia]]. The new type of tourmaline, which soon became known as paraiba tourmaline, came in blue and green. Brazilian paraiba tourmaline usually contains abundant inclusions. Much of the paraiba tourmaline from Brazil does not actually come from [[Paraíba]], but the neighboring state of [[Rio Grande do Norte]]. Material from Rio Grande do Norte is often somewhat less intense in color, but many fine gems are found there. It was determined that the element copper was important in the coloration of the stone.<ref name="Rossman et al. 1991">Rossman et al. 1991.</ref>
