Paraiba Tourmaline: Brazillian vs. African

Posted on October 23rd, 2013 in Paraiba Tourmaline, semi-precious gem stones by admin || No Comment

As we discussed in a previous post, The Paraiba label has transcended reference to region of origin for certain Tourmaline stones. Paraiba Tourmaline generally displays a number of defining attributes, but is mostly characterized by its unique blue and green coloring. The copper in the region has been found to be the catalyst to this special colorization through comparing Tourmaline samples from neighboring regions with significantly less copper within their source mine. More recently, with the interest in semi precious gem stones exponentially increasing around the world, prospectors have continued to find new examples of copper infused Tourmaline.

About a decade later, another large discovery of Tourmaline stones was found in a popular copper mining region of Nigeria. The African strain of Paraiba Tourmaline is usually less saturated and paler in nature than its Brazilian counterparts. Another discovery of copper infused Tourmaline stones located in Mozambique more closely resembles the color scheme and brightness found in the Brazilian stones, however, to this date, Paraiba Tourmaline (that actually originated in that region) is found to be the most uniform in brightness and color. So, the question remains, what is a better investment as a gemstone. Taking a look at color uniformity and average market prices, Brazilian Paraiba seems to hold value most effectively compared to African Paraiba.

The Gemological Institute of America has been, and continues to be, one of the largest forces in the unification of all aspects of gem research, education, classification, and collection. Founded in the early 1930s by Robert Shipley, the GIA’s goals were simple: to develop systems and methods to correctly classify and professionalize the industry. Since its inception, the GIA has become the premier resource for gem collectors, retailers, and scientist alike.

Among its most important milestones was the creation of the 4Cs and the international diamond grading system, which initiated a worldwide classification of diamonds. This idea then evolved into the GIA certification process. This process aims to certify as many gems as possible, from Green Tourmaline to Tsavorite Stones, through various characteristics such as clarity, carat, cut, and color, among other criteria. After decades of grading and certifying a vast array of gems, and even creating new technologies to help along the way, a GIA certification is now something that is sought after, and even required, by collectors of all types. It is now standard practice to check the status of a gem through the GIA to make sure every aspect of the gem is legitimate, from cut to area of origin. Color is now seen as the most important factor for a Gemstone and whether or not a particular gem can become certified–the gems pictured above are two of our finest examples of certified gems. Below is an example of what a genuine GIA Certification looks like!

The Paraiba Region of Brazil

Nested within the coastal region of northeastern Brazil is the lush state of Paraiba. First inhabited by Portuguese settlers in the 16th century, Paraiba has long been known for its amazing conditions for growing and producing sugar. History remained fairly static as the region continued to produce large amounts of sugarcane into the 1900s.

However, in the late 1980s, a prospector discovered a vein of semi precious gem stones, later known as Paraiba Tourmaline, and found them to be some of the highest quality of this crystal. In fact, the type of tourmaline that was first found in this region was such a fine vein of crystal that all other neon, copper-infused Tourmaline stones are labeled as Paraiba Tourmaline; regardless of the region of origin.
