RAPID COMMUNICATIONS GEMS & GEMOLOGY SPRING 2009 ver the past year, we examined nine blue to bluegreen Cu-bearing tourmalines from Mozambique that contained surface-reaching growth tubes and cracks that were outlined or “sleeved” with obvious pink color zones (e.g., figure 1). These gems came from four different gem dealers over the course of the year. The first gem, from Simon Watt, was a 14.12 ct blue heart-shaped mixed cut measuring 15.82 × 13.68 × 10.82 mm that was purportedly from Mozambique. As shown in figure 2, this tourmaline contained a surface-reaching growth tube sleeved by a pink zone of moderate intensity. Soon thereafter, Bill Vance and David Freeland Jr. sent us the 27.63 ct cushion mixed cut shown in figure 1. This gem, also said to be from Mozambique, measured 17.82 × 17.13 × 12.95 mm. It contained a surface-reaching macroscopic growth tube under its table that was enveloped along its length by an intense zone of pink (almost red) color, which created a clear contrast against the blue bodycolor of its host. The third and largest of the gems came into the GIA Laboratory for identification and origin determination. This tourmaline was a blue-green pear-shaped modified brilliant cut that weighed 33.26 ct and measured 24.34 × 19.88 × 12.89 mm. It contained several thin surface-reaching growth SOLUTION-GENERATED PINK COLOR SURROUNDING GROWTH TUBES AND CRACKS IN BLUE TO BLUE-GREEN COPPER-BEARING TOURMALINES FROM MOZAMBIQUE
